Configuring and Powering On the

Sun Storage J4500 Array

This chapter contains the following procedures and information:

Section 2.1 “Configuration and Cabling” on page 2-1

Section 2.1.1 “Terms and Definitions” on page 2-1

Section 2.1.2 “Configuration Rules” on page 2-2

2.1

2.1.1

Configuration and Cabling

The J4500 array can be connected to a supported HBA (Host Bus Adapter) installed in a server. The rules for connecting J4500 array are described here.

Terms and Definitions

There are several terms used in this document that you will need to become familiar with to better understand J4500 array configuration options.

Sun Storage J4500 Array Configuration Terms and Definitions

Daisy-chaining

(or cascading)

Definition

Host bus adapter (also called an initiator) is disk controlling circuity embedded on a motherboard, or an optional expansion card used to control a set of disks. Some HBAs support hardware RAID (Redundant

Array of Independent Disks), which is configured by the HBA software and provides redundancy in the event of a disk failure.

A device containing logical units and target ports that receives requests from, and responds to, an initiator. An example of a target device is a hard disk. Other terms used to describe a SAS target are “device” and “end device.” In multipath configurations, each hard disk is seen by the HBA as two targets.

A SAS fabric is conceptually similar to a network segment. A SAS fabric is made up of an initiator, targets, and a set of linked expanders that work like network switches linking end point devices (intitiators and targets) together as a discreet storage system. The J4500 array uses a dual fabric scheme with a primary SAS fabric “A” and a secondary, redundant SAS fabric “B”. A fabric can be expanded by daisy-chaining additional J4500 arrays. There are two 4-lane (or x4) connector ports (Port 0 and Port 1) per fabric. Each connector port links to all 48 disks.

This is a single path connection from a host to a one of the enclosure’s SAS fabrics (A or B). No path redundancy is available.

This is a dual path connection from a host to both of the array’s SAS fabrics (A and B). Provides two paths to the array’s disks and uses the redundant SAS fabric capability of the array for failover.

A method for linking several J4500 arrays together to increase the amount of available disks to the host. When cascading multiple arrays using a multipath configuration, Sun recommends cascading the host links in opposite directions from the edge of the SAS fabrics to prevent a single array failure from preventing access to other arrays in the cascade.

Zoning is a configuration method that takes the available connected storage and allows each host to have its own storage resources. Zoning is done on a per hard disk level and hard disks owned by one host cannot be accessed by other hosts. Sun Common Array Manager (CAM) version

6.4.1 software is required to perform host initiator-to-disk access configuration (zoning).

Configuration Rules

Before attaching cables to the J4500 array, read through the following configuration rules:

2-2

Sun Storage J4500 Array Service Manual • March 2013

2.1.2.1

General Rules

The array enclosure drive bays must be fully populated. All 48 SATA hard disk drives must be present and the same size. Do not mix drive capacities in the array enclosure; however you could, for example, have one J4500 populated with 750

GB SATA drives and a daisy-chained J4500 array with 1 TB SATA drives. The

J4500 array does not support SAS drives.

The mini-SAS connector ports are configured as follows: Port 0 uses subtractive or direct routing (indicated by the circle icon above the connector, see

FIGURE 2-1

) and connects to upstream devices (either an HBA, or an upstream J4500 array). Port 1 is universal (indicated by the diamond and circle icons), using table and direct routing, and connects to either an upstream HBA or a downstream J4500 array.

Use only supported mini-SAS x4 cables (SFF-8088). There are two cables included with the array. Refer to

Section 3.1 “Options and Replaceable Components” on page 3-1

for additional cable options. Maximum cable lengths between devices is 6 meters. Using non-Sun certified cables or longer cables is not supported.

Do not cross connect an array enclosure’s SAS fabrics. The SAS A ports of an

array enclosure must not be cross connected to its SAS B ports

.

Caution –

Cross connecting the SAS fabrics of a J4500 array (connecting its SAS A ports to its SAS B ports) can cause the HBA to be unable to properly identify or access drives in the array which could lead to data loss.

2.1.2.2

Connecting Host Bus Adapters (HBAs)

HBAs can be connected as follows:

Use only supported HBAs with the array. At initial release, supported HBAs for use with your array product are:

Sun StorageTek SAS RAID Eight-Port, External HBA (SG-XPCIESAS-R-EXT-Z,

Adaptec™-based RAID controller). Single path configurations only.

Sun StorageTek PCI Express SAS 8-Channel External HBA (SG-XPCIE8SAS-E-Z,

LSI™-based disk controller). Single or multipath configurations supported.

Sun StorageTek ExpressModule SAS 8-Channel External HBA

(SG-PCIE8SAS-EB-Z, LSI-based disk controller). Single or multipath

configurations supported.

An updated list of supported HBAs is maintained in the Sun Storage J4500 Array

Product Notes (820-3162) available on the Sun documentation web site http://docs.sun.com

.

A single path configuration consists of a single SAS cable connecting a single HBA to one of the array’s SAS fabrics, either A or B.

Chapter 2 Configuring and Powering On the Sun Storage J4500 Array

2-3

A multipath configuration consists of connections to both of the J4500 array’s SAS fabrics, A and B, using one or more HBAs in order to create a dual path. More on configuring your array for multipathing can be found in the Sun Storage J4500

Array System Overview (820-3163).

Configuring zoning of the array storage is currently only available using the Sun

Common Array Manager (CAM) through an LSI-based HBA connected to the array. For more information on zoning, see the Sun Storage J4500 Array System

Overview (820-3163).

Note –

The J4500 array is not supported in a clustering configuration.

2.1.2.3

2.1.2.4

Connecting Multiple Sun Storage J4500 Arrays

Sun Storage J4500 arrays can be daisy-chained, or cascaded, together as follows:

The maximum number of arrays that can be daisy-chained together is limited by the number of SAS targets (also called “devices” or “end devices”) supported by the attached HBA. Check the HBA’s documentation to see how many SAS targets are supported. Also see

Section 2.1.2.4 “SAS Target Limits” on page 2-4

.

In single path configuration, arrays may be cascaded from Port 1 (out) of the upstream array to Port 0 (in) of the downstream array. Array cascade port connections must be of compatible types (for example, no array cascading from

Port 1-to-1, Port 0-to-0, or Port 0-to1

).

In a multipath configuration (creating a dual path by utilizing both SAS fabrics),

Sun recommends cascading the host links in opposite directions from the edge of the SAS fabric. For example, the first host connection goes to the top of the SAS A fabric and cascades down, while the second host connection goes to the bottom of the SAS B fabric and cascades up. Array cascade port connections must be of compatible types (for example, no array cascading from Port 1-to-1 or Port 0-to-0).

For more on configuring for multipathing, see the Sun Storage J4500 Array System

Overview (820-3163).

Do not mix a J4500 array with any other type of JBOD array in a daisy-chain.

Check the Sun Storage J4500 Array System Overview (820-3163) for updated configuration information.

SAS Target Limits

To ensure a given configuration of J4500 array’s does not exceed the HBAs’ target

limit

, the following rules apply:

For single path configurations, each hard disk visible to an HBA consumes one target.

2-4

Sun Storage J4500 Array Service Manual • March 2013

2.1.2.5

2.1.3

For multipath configurations, each hard disk visible to an HBA consumes two targets.

Each expander visible to an HBA consumes three targets. There are two expanders per SAS fabric in the array.

When zoning is being used on array storage, there must be a host that runs the zoning manager. This host must be able to communicate with all targets in the system. This means that the number of targets seen by the zoning host’s HBA(s) must not exceed the target limit for that HBA.

Refer to your HBA documentation to find out how many targets it can support.

Targets might also be called “devices” or “end devices.”

Configuration with Blade Servers

For Sun Blade Server Modules, the same configuration rules listed above for Sun

Storage J4500 arrays apply with the following blade-specific rules:

An array may be connected to a Sun Blade Server Module in single path or

multipath

configuration using a supported SAS PCIe ExpressModule HBA that includes SAS x4-wide connectors. An updated list of supported HBAs are maintained in the Sun Storage J4500 Array Product Notes (820-3162) available on the

Sun documentation web site.

The array may not be connected to a SAS NEM in the chassis (a Network

Expansion Module that includes external SAS connectors). A server blade may also have its own set of drives and expanders, or be connected to a storage blade and already be using the SAS NEM. This can limit the number of available SAS targets supported by the blade server’s internal HBA. Therefore, the J4500 array should only be connected to a supported SAS PCIe ExpressModule HBA that is used exclusively to connect external SAS devices.

Cabling the SAS Connectors

The following figure shows the SAS connector ports for cabling J4500 array to your server’s HBA. Before cabling a J4500 array to your server’s HBA, refer to the

Section 2.1 “Configuration and Cabling” on page 2-1 .

Powering On and Off the Array

The Sun Storage J4500 array has two levels of power: standby power and main power. The initial setup of the array should be done before plugging in AC power.

The procedures for powering on to main power mode and going from main power mode to standby power mode are included in this section.

Chapter 2 Configuring and Powering On the Sun Storage J4500 Array

2-11

Caution –

Do not operate the enclosure without all fans, component heatsinks, air baffles, and covers installed. Severe damage to enclosure components can occur if the enclosure is operated without adequate cooling mechanisms.

▼ To Power On the Array

The proper power-up sequence for a system connected to the Sun Storage J4500 array is to first power on the array, wait one minute, then power on the host server. This wait time allows all 48 array hard disk drives to power up to the point where the server can see them and helps reduce the number of start-up device link messages saved to the server’s log file

To apply main power to the array, do the following:

1. Connect two grounded AC power cords to the two AC power supply connectors at the back of the array enclosure.

2. Then connect the other ends of the two AC power cords to grounded AC

(110-220 VAC) power outlets.

Connecting the AC power cords to the array automatically applies main power to the array. In main power mode, the array Power/OK LED next to the Power button lights and remains lit.

Note –

See the service label on the hard disk drive access cover for an explanation of the LEDs on the hard disk drives, fans, power supply, and system controller. Or, refer to

Chapter 4 .

▼ To Place the Array Into Standby Power Mode

The front panel power button is used to switch the array from main power to standby power (or from standby power back to main power). Standby power mode leaves the power supplies partially on, but powers down the enclosure hard disks,

SAS expanders and SAS links.

1. To switch the array enclosure from main power mode to standby mode, use a stylus to press and hold in the power button on the front panel (see

FIGURE 1-2

)

for 5 or more seconds (during which the locate LED will flash).

As the enclosure enters standby power mode, the Power/OK LED on the front and back panel blinks, indicating that standby power mode is working.

2-12

Sun Storage J4500 Array Service Manual • March 2013

2.2.1

2. Release the power button on the front panel.

With AC power connected, the array takes about 10 seconds to go fully into standby power mode.

Caution –

To power off the array completely, you must disconnect the AC power cords from the back panel of the array enclosure. It takes a full 20 seconds with the

AC power cords unplugged for internal power to be completely drained from the enclosure.

3. To reapply main power to the array from standby power mode, use a stylus to press and release the recessed Power button on the array front panel. See

FIGURE 1-2

.

When main power is applied to the array, the Power/OK LED next to the Power button lights and remains lit.

▼ To Power Off the Array

To power off the array completely, you must disconnect the AC power cords from the power supplies at the back of the array enclosure. The power switch is only used for putting the array into standby power mode, or applying main power from standby power mode. Do the following to power off the array:

To completely power off the array, disconnect the two AC power cords from the power supplies at the back of the enclosure.

It takes a full 20 seconds with the AC power cords unplugged for the internal power to be completely drained form the enclosure.

AC Power Failure Auto-Recovery

If AC power is temporarily lost to the array, for example if the municipal power grid experiences an outage, the array automatically restarts to main power mode when power is restored. No user intervention is required.

The same behavior occurs if you disconnect the AC power cords from the back of a powered-on array and then reconnect them.

Powering Off the Array and Removing It

From the Rack

Use the procedures in this section when you are referred to them from the removal and replacement procedures.

▼ To Power Off the Array

Before attempting to work inside the array enclosure, power it down as follows:

1. Shut down the J4500 array from main power as described in

Chapter 2

.

Caution –

When you use the Power button to enter standby power mode, power is still directed to the power supply fans, indicated when the Power/OK LED is flashing. To completely power off the array enclosure, you must disconnect the AC power cords from the back panel of the array.

2. Disconnect both power cords from the array’s power supplies.

3. Disconnect any other cables that must be disconnected in order to remove and replace a specific component.

It is a good idea to label your cables as you disconnect them to ensure correct reconnection.

Caution –

Before handling components, attach an electrostatic discharge (ESD) wrist strap to a grounding point on the chassis. The system’s printed circuit boards and hard disk drives contain components that are extremely sensitive to static electricity.

▼ To Remove the Array Enclosure From the Rack

This procedure assumes you have turned off the system and removed any cables or cords that would restrict the movement of the system.

Caution –

To avoid serious personal injury and/or equipment damage while handling or moving this product, always use all four chassis handles to support the product weight. These systems can weigh up to 170 pounds (77 kg) when fully loaded with components. If only three people are available, remove power supplies, hard disks, and system controller to reduce the weight to about 50 pounds before removing the system. Leave the fan trays installed. Attempting this procedure without a mechanical lift or with fewer than four people could result in personal injury or equipment damage.

1. If you do not have a mechanical lift, remove the following components from the rear of the rack to reduce the weight to a safe level for manual lifting:

To remove power supplies, see

“To Replace a Power Supply” on page 3-26 .

Chapter 3 Maintaining the Sun Storage J4500 Array

3-17

▼ To Replace a Hard Disk Drive

This section describes how to remove and replace a hard disk drive. The J4500 array comes fully populated with 48 SATA drives installed. When replacing drives, note the following:

Replacement drives must be SATA, of the same capacity, and the same manufacturer as the drive being replaced. If is configured for multipathing, only supported drives may be used (for more on drives supported for multipath, see

Section 4.4.5.4 “Multipath Problems With Unsupported Drives” on page 4-14

).

Drives are a hot-pluggable CRU and can be replaced by anyone. Hot-pluggable means that the hard drive must be first brought offline by using a management software or operating system command; however, the array does not need to be powered off.

A single hard disk failure does not cause data loss if the hard disk is part of a

RAID 1 (or higher) volume. The hard disk can be hot-plugged (but not hot-swapped). When a new hard disk is inserted, the contents are automatically rebuilt from the rest of the array with no need to reconfigure the RAID parameters. If the bad hard disk was configured as a hot spare, the new hard disk is automatically configured as a new hot spare.

Do not configure RAID volumes with drives of different capacities. This can cause unexpected operation or other problems. All drives in the array enclosure must be

SATA and of the same capacity.

Each hard disk has a physical drive number, a map of the array hard disks is shown on the service label.

When using Linux hosts, if you add or remove array disks the host might hang or panic due to known Linux kernel issues. If you encounter this problem, a reboot of the host should resolve it.

Caution –

To avoid overheating the array enclosure, do not leave a hard disk drive out for longer than 60 seconds at a time when the array power is on. Remove and replace only one hard disk drive at a time. Replace the hard disk drive access cover as soon as the service tasks are completed.

1. Remove the hard disk drive access cover as described in

“To Remove the Hard

Disk Drive Access Cover” on page 3-9

.

2. Identify the defective hard disk by looking at the hard disk LEDs.

If the amber (middle) LED is on, the drive is faulty and should be replaced.

3-18

Sun Storage J4500 Array Service Manual • March 2013

3. A failed drive should have already been taken offline by the system. If you want to remove a drive that has not failed (the amber LED is not lit), use the operating system or array management software to take the hard disk offline before you remove it. Not doing so could cause data loss or unexpected error messages.

Caution –

Taking a disk offline that is part of a non-redundant logical drive causes the entire logical drive to fail and result in data loss.

If you are using an operating system command line, note that disks in the enclosure are typically identified in sequential order. Although the enclosure contains only 48 disks, your operating system may see a list of 51 devices; if this is the case, the first 4 addresses (0-3) represent the enclosure's four SAS expanders, the other 48 addresses (4-51) represent the 48 hard disks.

Once the drive has been taken off line, the blue ready-to-remove LED should turn on. This means the drive is ready to be removed and service action is allowed.

4. Remove the hard disk.

Lift the metal latch and remove the hard disk from the drive bay as shown in

FIGURE 3-12

, or on the service label.

▼ To Replace a Power Supply

This section describes how to remove and replace a power supply.

The power supplies are fully redundant from 110 to 220 VAC; if one power supply fails, the other power supply will continue to operate.

Note –

This component is a hot-swappable CRU and can be replaced by anyone.

Hot-swappable means that you do not need to power off the array during replacement. However, you must unplug the power supply to be replaced or the entire system could shut down during removal.

The physical numbering of the two power supplies in the array enclosure is shown on the service label.

1. Identify which power supply you will replace. Each power supply has one fault

LED that you can view from the rear of the array enclosure. If the LED is amber, the power supply is faulty and should be replaced.

2. Disconnect the AC power cord from the power supply that you are replacing.

The power supplies are hot-swappable, so you do not have to shut down the array or disconnect AC power from the other working power supply.

3-26

Sun Storage J4500 Array Service Manual • March 2013

Note –

▼ To Replace the System Controller Module

The system controller (SC) consists of a sub-enclosure module and board that are removed as a unit from the back of the array enclosure. The system controller board contains the SAS expanders used to access the enclosure’s 48 hard disk drives. The module is replaced as a unit—there are no replaceable parts inside.

Note the following before you begin:

3-28

Sun Storage J4500 Array Service Manual • March 2013

If the array was configured for zoning (array storage divided among multiple initiators), ensure that the zoning configurations created with the Sun Comman

Array Manager (version 6.4.1 at a minimum) have been exported to a file. Zoning configurations (including initiator-to-disk access and SAS domain passwords) are saved on the array’s SAS expanders in the SC. You will need to import these configurations (per initiator and SAS domain) after you replace the SC. Refer to the chapters on zoning and multipathing in the Sun Storage J4500 Array System

Overview (820-3163) for proper initiator-to-disk access configuration.

Be sure that you have first taken the array offline to prevent any host computer processes attempting to accessing it while the system controller is removed.

Be aware of SATA affiliations. When SATA drives are used, an affiliation

(dedication) to the initiator (HBA port) is automatically created. This complies with the SATA protocol and is point-to-point in nature. If multiple initiators are attached to a single SAS fabric (either SAS A or B), the drive-to-initiator affiliation will be arbitrarily chosen which can create potential issues (such as disks or initiators not being seen). Refer to the chapters on zoning and multipathing in the

Sun Storage J4500 Array System Overview (820-3163) for proper initiator-to-disk access configuration. Also refer to the Sun StorageTek Common Array Manager

Release Notes for the version of CAM being used.

Caution –

To prevent electrostatic discharge (ESD) damage to the components on the system controller, connect a ground strap between yourself and the chassis ground before proceeding. See

FIGURE 3-7

.

1. Disconnect the power cables from the array.

Caution –

Although both power supplies should turn off when you remove the system controller, voltage could be present on the chassis connectors if either power supply did not shut down as expected. Thus, you must disconnect the power cords from the power supplies and wait 20 seconds to avoid any risk from inadvertent contact with those connectors.

2. Disconnect the SAS cable(s) connected to the system controller (SC) module.

You must label where your cables are connected as you disconnect them to ensure correct reconnection to a supported configuration.

3. Use a Phillips screwdriver to loosen the SC module handle lock screw. See

FIGURE 3-19

.

4. Rotate the handle downward and pull the SC module from the chassis with one hand while supporting the system controller weight with the other hand.

5. Slide out the SC module from the chassis.

Note that the SC module is connected inside the enclosure to the power distribution board, you may need to exert some pressure to disengage it.

6. To install the new SC module, first remove the plastic connector covers on the replacement SC module.

Caution –

The module will not plug into the power distribution board with the connector covers on.

7. Align the SC module with the empty bay in the chassis.

8. Push the SC module into the bay until it stops (about three-quarters of the way in when it encounters the power distribution board connectors).

3-30

Sun Storage J4500 Array Service Manual • March 2013

9. Use your thumbs to apply pressure to the upper right and left corners of the module and firmly push the SC module into place.

As the module engages the power distribution board, the module handle will lift into place.

10. Once the module is fully seated on the power distribution board, finish rotating the SC module handle up and into place (see

FIGURE 3-20

). Then tighten its securing screw.

FIGURE 3-20

Replacing the SC Module

11. Reattach any cables you previously unplugged from the SC module. Ensure that the cables are fully and properly seated.

12. Place the plastic connector covers you removed from the new SC module on to the connectors of the defective SC module for return to the factory.

Chapter 3 Maintaining the Sun Storage J4500 Array

3-31

13. If the array was configured for zoning or multipathing, you will need to re-establish the appropriate initiator-to-disk access configuration using the Sun

Common Array Manager (version 6.4.1 at a minumum).

Detailed instructions for configuring zoning and multipathing for the array can be found in the Sun Storage J4500 Array System Overview (820-3163) and the Sun

StorageTek Common Array Manager Release Notes for the version of CAM being used.

Upgrading Enclosure Firmware

The Storage J4500 array enclosure contains upgradable firmware. You may want to upgrade the enclosure firmware to:

Install the latest bug fixes and performance enhancements

Add new features and capabilities as they become available

The Sun Common Array Management (CAM) software provides firmware upgrade capabilities for the J4500 array connected to any supported HBA. For more information on using the CAM software, see the Sun Storage J4500 Array System

Overview (820-3163).

Ensure Both SAS Fabrics are Upgraded to the

Same Firmware Revision Level

The J4500 array contains two SAS fabrics (A and B). Each fabric has its own set of

SAS expanders. The firmware upgrade process is only performed on the fabric with the active SAS link to the HBA. When upgrading enclosure firmware, Sun recommends that you upgrade firmware on both SAS fabrics to ensure they are at the same revision level.

This will require you to take the following steps:

Chapter 3 Maintaining the Sun Storage J4500 Array

3-33

1. Using CAM, perform the upgrade on the enclosure’s primary SAS fabric.

2. Then, at a convenient time, move the SAS cable to the enclosure’s secondary SAS fabric.

When performing this action, allow time between the removal of the link from the primary fabric and the reconnection to the secondary fabric for your HBA to recover from the lost and then re-established SAS link. Depending on the HBA, this can take up to 2 minutes each time the link state is changed.

3. Using CAM, perform the upgrade on the enclosure’s secondary SAS fabric.

Diagnostic and Management Tools

For the most part, you will need to use a combination of HBA and array management tools, log files, and enclosure LEDs to help isolate problems. However, available system level software, such as SunVTS™, may contain additional tools for problem identification/resolution.

SunVTS

SunVTS is the Sun Validation Test Suite, which provides a comprehensive diagnostic tool that tests and validates Sun hardware by verifying the connectivity and functionality of most hardware controllers and devices on Sun platforms. SunVTS software can be tailored with modifiable test instances and processor affinity features.

SunVTS 6.2 or later software might be preinstalled on some Sun servers or included as bootable Diagnostics CD. Booting the system with the CD in the server’s internal

DVD drive starts SunVTS software. Diagnostic tests run and write output to log files that the service technician can use to isolate problems.

Common Array Manager (CAM)

The Sun StorageTek Common Array Manager (CAM) software includes the Service

Advisor application, which provides guided wizards with system feedback for hardware replacement of Customer Replaceable Units (CRUs). In addition, Service

Advisor provides troubleshooting procedures for alarms.

Note –

All Field Replaceable Units (FRUs) are also CRUs in the J4500 array.

Before you can access Service Advisor procedures, you must have already installed the Common Array Manager software, as described in the Sun StorageTek Common

Array Manager User Guide for your version of CAM.

Enclosure management (including viewing the event log and upgrading enclosure firmware) and remote command line interface (CLI) functions are performed by the

Sun StorageTek Common Array Manager software.

Understanding the CAM Event Log

This section provides a listing of possible J4500 array events, descriptions, and where applicable, Service action recommendations.

Refer to the Sun StorageTek Common Array Manager User Guide for your version of

CAM for information on viewing system events and configuring automatic notifications.

The severity of an event in CAM is includes one of the following designations:

Down: Identifies a device or component as not functioning and in need of immediate service.

Critical: Identifies a device or component in which a significant error condition is detected that requires immediate service.

Major: Identifies a device or component in which a major error condition is detected and service may be required.

Minor: Identifies a device or component in which a minor error condition is detected or an event of significance is detected.

Note –

When Auto Service Request (ASR) is enabled, it monitors the array system health and performance and automatically notifies the Sun Technical Support Center when critical events occur. Critical alarms generate an Auto Service Request case.

The notifications enable SunService to respond faster and more accurately to critical on-site issues.

“Array Environment Problems” on page 15

“Power Problems” on page 16

Initial Start-up

If you are unable to see the array drives after powering on the array, check the following:

Ensure all cables are properly connected (power and SAS).

Chapter 4 Troubleshooting

4-9

4.4.2

4.4.2.1

Be sure you are using SAS cables supported for use with the array. Using longer, or non-certified cables is not supported. For a list of supported cables, see

Section 3.1 “Options and Replaceable Components” on page 3-1 .

You should carefully follow the configuration rules listed in

Section 2.1

“Configuration and Cabling” on page 2-1 . Not following these rules could result

in an unsupported configuration.

Check the array indicator LEDs to make sure all components are operating normally and the link LEDs are green.

The proper startup sequence for the enclosure is to power-on the enclosure first, wait one minute, then power-up the server.

Check the Event and Performance Logs

The operating system event log is a good first place to start in identifying problems or potential issues with the enclosure or its disks. If you experience disk problems, such as disk errors or invalid read/writes, the system event log can help identify the problem disk.

Note –

By default, errors for the enclosure (temperature, voltage, device status), may not be logged in the system event log, but only in the array management software event log. If you want errors to be forwarded to the system event log, refer to the

HBA documentation to see if it supports this feature.

You may have problems with the array listed in multiple log files (system and HBA).

If this is the case, concentrate on recent errors that best relate to the problem. Try to pinpoint the time when problems began to appear. Search through the log files as soon as possible for when the problems first appeared—log files can quickly fill up with errors and some information may be lost.

Identifying Disks in the Array Enclosure

Disks in the array enclosure are typically identified by the operating system in sequential order in a list of 51 devices; the first 4 addresses (0-3) represent the array's four SAS expanders, the other 48 addresses (4-51) represent the 48 hard disks. Drives are mapped in numerical order as shown on the drive map label on the top of the array enclosure. Device names and address information depends on other mass storage devices attached to the server and where the array’s HBA is located in the

PCI bus boot order.

Common Array Manager, or the Sun StorageTek RAID Manager software) to provide a system administrator at the array-connected server or network-connected management console the following capabilities:

Monitor the enclosure status (on/off line status, component health)

Monitor the enclosure environment (voltage and temperature)

Remotely identify and locate enclosure components

Obtain FRU identification and status (expanders, hard disks, fans, power supplies)

Remove and install FRU components

Remotely reset the enclosure hardware

Remotely upgrade the enclosure’s firmware (expanders and hard disk—must use

CAM)

View the enclosure event log to aid in troubleshooting

Refer to the Sun Storage J4500 Array System Overview (820-3163) for more information on array management software.

Array Link Problems

You may encounter a problem where the server is unable to communicate with the array. Complete the following troubleshooting tasks to reestablish communications with the array.

Check the SAS link LEDs at the rear of the enclosure (see

Section 4.1 “External

Status LEDs” on page 4-1 ) to ensure the ports are properly communicating with

the HBA. Each SAS port has a SAS Link Activity LED. The following LED states will be viewable:

On – 1 to 4 links are ready.

Blink – Read/Write port activity.

Off – Link is lost.

If the link LED is off, check the SAS cables for proper connection. Ensure that the cables are supported for the enclosure (refer to

Section 3.1 “Options and

Replaceable Components” on page 3-1

).

Chapter 4 Troubleshooting

4-11

4.4.4.1

If you can not reestablish communication with the server, you can try resetting the enclosure hardware. The enclosure hardware may be reset with the power on. See

Section 4.5 “Resetting the Enclosure Hardware” on page 4-16 . You may also

remotely reset the enclosure through the Sun Common Array Manager.

There may be a problem with SAS fabric you are using. Try using the redundant fabric. If you have daisy chained J4500 arrays, be sure to move all cable connections to the redundant fabric—only one SAS fabric (SAS A or SAS B) may be used per HBA port connection. Cross fabric connections on an array enclosure

(SAS A to SAS B) are not supported.

There may be a problem with the SAS cable. The cable might be damaged and either prevents communication, or it may allow only degraded communication

(which can manifest itself in poor array performance). The array comes with two cables, try attaching a new SAS cable.

Review the Sun and server operating system vendor knowledge base to see if the problem is a known issue with a solution, also see the Sun support site http://www.sun.com/support

. The J4500 array SAS expanders have firmware that may be upgraded as fixes and new features become available from Sun. For more information on upgrading enclosure firmware, see

Section 3.7 “Upgrading

Enclosure Firmware” on page 3-33 .

Switching SAS Cables or Making New Connections

In a single path environment:

If your J4500 array is connected to the StorageTek SAS

RAID External HBA, and you switch a cable from one port of the HBA to the other port on the HBA, you should wait long enough after the initial cable pull for all the physical hard drives shown in the GUI or through the CLI to be removed from the display. This prevents the problem of the controller attempting to remove drives at the same time it is reading the same drives on another port. If no display is available, you should wait at least 2 minutes between pull and reconnect.

In a multipath environment:

Since the J4500 array uses SATA drives, the potential for SATA affiliation conflicts exists. Conflict can occur when more than one initiator tries to access the drive via the same path (for example, two hosts attached to SAS A on a J4500 array), or if you move an established connection from one domain port to another (for example, from port 0 to port 1). Possible symptoms of SATA affiliation conflicts are: operating system hangs, zoning operations take longer than 10 minutes to complete, and/or disk utilities like “format” will not return device lists in a timely fashion. For more about SATA affiliations, see the Sun Storage J4500 Array System

Overview (820-3163).

Disk Problems

Issues with array disks might be identified by viewing the system event log, being alerted by your array management software, or by viewing the J4500 array’s LEDs. In the event of a disk failure, the disk may be replaced with the array online.

▼ To Replace a Disk

If the disk must be replaced, complete the following tasks:

1. Slide the J4500 array out of the rack far enough to remove the disk top cover panel. See

“To Remove the Hard Disk Drive Access Cover” on page 3-9

.

2. To replace a disk, use the operating system, or enclosure management software command to unmount the disk and prepare it for removal. This is required to isolate the disk and stop all read/write activity.

3. Identify the physical disk to be removed by looking for the blue ready-to-remove LED, or the amber failed LED, on the disk. Then, remove the disk. For step-by-step procedures for removing disks from the enclosure, see

“To Replace a Hard Disk Drive” on page 3-18

.

4. Replace the disk, then use the operating system or enclosure management software commands to remount the disk. If the disk is part of a RAID volume, it will automatically rebuild with the required data after replacement.

4.4.5.1

4.4.5.2

Guidelines for Removal and Replacement of RAID Storage

When removing and replacing RAID disks in the J4500 array, use the following guidelines:

Perform RAID disk removal and replacement procedures with the system powered on. That way, the HBA can update its RAID configuration information.

When removing and replacing disks, allow enough time between each operation for the HBA to update the RAID configuration information. When hot-plugging non-failed drives for test purposes, you should wait a full minute after removal before reinserting the drive.

Persistent Affiliation When Changing HBAs

When connecting your array to an HBA, it is possible that the SAS “affiliation” feature may cause problems if the array was previously connected to another HBA.

An affiliation is used by the SAS protocol to prevent multiple SAS initiators (HBAs)

Chapter 4 Troubleshooting

4-13

4.4.5.3

from interfering with each other when communicating with SATA drives. If you encounter such a problem, affiliations may be removed by power cycling the array enclosure prior to connecting it to a different HBA.

If You Do Not See All of the 48 Disks

If you see only some of the available disks (for example, if you see only 20 or 28 of the total 48 disks), try the following:

Look through the vents at the back of the System Controller module to see if the 4 green expander heartbeat LEDs are blinking. If not, try power cycling the array.

If the problem occurs repeatedly, there might be a problem with the System

Controller module. Check in the Sun Common Array Manager (CAM) to see if the array is at firmware baseline, if not, you should upgrade the array firmware.

If updating the array firmware does not solve the problem, the System Controller module may need to be replaced. For step-by-step procedures for replacing the

System Controller module, , refer to

“To Replace the System Controller Module” on page 3-28

.

If you have moved SAS cables from one port to another, you may have SATA affiliation conflicts. Conflict can occur when more than one initiator tries to access the drive via the same path (for example, two hosts attached to SAS A on a J4500 array), or if you move an established connection from one domain port to another

(for example, from port 0 to port 1). Possible symptoms of SATA affiliation conflicts are: operating system hangs, zoning operations take longer than 10 minutes to complete, and/or disk utilities like “format” will not return device lists in a timely fashion. Refer to the chapters on zoning and multipathing in the Sun

Storage J4500 Array System Overview (820-3163) for proper initiator-to-disk access configuration. Also refer to the Sun StorageTek Common Array Manager Release Notes for the version of CAM being used.

4.4.5.4

4-14

Multipath Problems With Unsupported Drives

Only SATA hard disk drives supported for use with the J4500 array may be used for multipathing. If you install an unsupported drive, you might get the following error in the System Event Log and you will be unable to configure the drive for multipath:

Target:2, lun:0 doesn’t have a valid GUID, multi pathing for this drive is not enabled

This error means that the drive does not have a SAS WWN (World Wide Name). All drives supported for use with the J4500 array have a unique WWN. The WWN does not change even if the drive firmware is upgraded.

At the release of this document, the following Sun hard disk drives are supported for use in the J4500 array (check the label on the drive to verify it is a supported):

Note –

The J4500 array is shipped from the factory with drives of the same capacity.

Mixing drives of different capacities in the array is unsupported. Refer to the Sun

Storage J4500 Array Product Notes (820-3162) for updated information.

4.4.6

Array Environment Problems

The array enclosure needs to operate within a specific temperature range (below 35

˚C or 95 ˚F). If the internal temperature is above that, the fans automatically increase in speed when a thermal threshold is reached. This could be a reaction to higher external ambient temperatures in the local environment. If the fan noise level and tone seem high, check to ensure there is no airflow restriction raising the enclosure’s internal temperature.

If an excessive temperature threshold is reached that could damage components in the enclosure, the J4500 array Over Temperature LED will light. If this happens do the following:

Use your array management software to check for a faulty fan. An enclosure fan is a hot-swappable and may be replaced with the power on. The fans include status

LEDs to identify a faulty fan. For step-by-step procedures for replacing enclosure fans, refer to

“To Replace a Fan Module” on page 3-12 .

Check that there is clear, uninterrupted airflow at the front and rear of the storage system.

Check for enclosure intake restrictions due to dust buildup and clear them.

Check for excessive recirculation of heated air from the rear of the array enclosure to the front.

Reduce the ambient temperature in the room where the array enclosure is racked.

Chapter 4 Troubleshooting

4-15

4.4.7

Power Problems

The J4500 array includes redundant, hot-swappable power supplies. If a power supply fails, you may be alerted by the array management software or the enclosure power supply status LEDs (an alert LED will light amber both at the front and rear of the enclosure when service is required). For step-by-step procedures for replacing an array power supply, see

“To Replace a Power Supply” on page 3-26 .

4.5

Resetting the Enclosure Hardware

In the event the array becomes non-responsive to host commands or you cannot see its disks, you may need to reset the array enclosure hardware. You can reset the array with the power on. The array takes about 1 minute to reset before relinking to the host.

Note –

The enclosure may be reset remotely using the Common Array Manager

(CAM) software.

▼ To Reset the Enclosure Hardware Using the

Reset Button

Resetting the array is done by pressing a recessed button at the rear of the enclosure

(see

FIGURE 4-3

). The array may also be reset remotely using the Sun Common Array

Manager.

Note –

This procedure should only be performed after you’ve checked of other problems at the server and have shut down all server processes that are actively accessing the J4500 array.

1. At the back of the J4500 array, locate the enclosure Reset button (see

FIGURE 4-3

).

2. Using a paper clip or stylus, press and release the recessed button on the back panel.

The reset process takes about 1 minute. After that, the server should see the array disks.

Clearing the Enclosure Zoning Password

When creating storage zones on your J4500 array, use the Common Array Manager

(CAM). CAM allows you to set a zoning password for each of the array’s SAS domains (each domain equates to one of the array’s SAS fabrics: A or B). The zoning passwords are stored in the array expanders and in CAM, and are used to prevent unauthorized changes to storage zones. If the array’s zoning password is ever forgotten, or becomes corrupt, it can be cleared using the enclosure zoning password clear button on the back of the J4500 array.

Note –

Using the enclosure zoning password clear button clears the zoning password for both of the J4500 array’s SAS domains. It does not clear zoning configurations.

After clearing the zoning password on the array enclosure, you will also need to clear the zoning password for each of the array’s SAS domains stored in CAM. This can be done from the CAM management host. Once the password is cleared in both places, you can use CAM to assign a new password to each of the array’s SAS domains.

Chapter 4 Troubleshooting

4-17

Note –

Clearing the password in both places is important to ensure the passwords stored in the array and in CAM match. Some CAM array maintence operations use the enclosure zone password during execution to ensure the action is authorized.

▼ To Clear the Enclosure Zoning Password

Clearing the enclosure zoning password is done by pressing a recessed button at the rear of the array. This operation may be performed with the enclosure running.

1. At the back of the J4500 array, locate the Enclosure Zoning Password Clear button (see

FIGURE 4-4

).

2. Using a paper clip, press and hold the recessed button on the back panel for five seconds and then release.

The enclosure zoning password for both SAS fabrics (A and B) is cleared.

FIGURE 4-4

Enclosure Zoning Password Clear Button

Enclosure Zoning Password Clear button

3. From the CAM management host, select Clear password from the

Administration page and saving the setting for both of the array’s SAS domains.

Once that is done, you can assign new zoning passwords using CAM.
