10 About this guide

1 FRUs

AssuredSAN Pro 5000 Series paged storage systems consist of a base configuration and possible add-on components. A base configuration includes a controller enclosure attached to either one 24-drive expansion enclosure or two 12-drive expansion enclosures for a minimum of 48 disk slots (see the “Product models” and “Supported configurations” topics in the Setup Guide for more information about base model configurations and add-on components). This document addresses available FRUs at the enclosure level.

Available FRUs

You can determine which FRUs pertain to your storage enclosure using the Command-line Interface (CLI).

Access the controller via a Telnet client; log into the controller over the network (default user name manage and password

!manage

). If the default user or password—or both—have been changed for security reasons, enter the secure login credentials instead of the defaults shown above.

Enter a show frus

query.

Execution of the show frus

CLI command displays controller metadata, followed by the FRU information pertaining to chassis (with midplane), I/O modules (IOMs), and power supplies.

NOTE: See AssuredSAN Pro 5000 Series CLI Reference Guide for more information.

You can also determine which FRUs pertain to your storage enclosure by visual inspection of the component, noting serial number and part number . This method applies to disk drives. FRUs and FRU make-up are subject to change independent of documentation versions. Information about FRUs and other components can also be viewed via the Storage Management Console (SMC).

Automatic pooling for disks in supported configurations

SMC provides an automatic pooling feature for provisioning disks in properly configured enclosures.

During first-time configuration of a new system, auto-pool enables you to quickly provision the storage in all connected enclosures so that you can start creating volumes and mapping them to hosts. Over the life of the system, auto-pool enables you to add disks or enclosures to provide additional storage for existing storage pools. Auto-pool also enables you to remove storage.

IMPORTANT: See

Disk drive slot numbers and auto-pool provisioning on page 30 for more information.

AssuredSAN Pro 5000 Series does not support a standalone 24-drive controller enclosure; it must at minimum be attached to either one 24-drive expansion enclosure or two 12-drive expansion enclosures for a minimum of 48 disk slots. The minimum storage pool size is 500 GB. RAID-6 and RAID-10 components require two spares per disk type used in a supported storage configuration.

IMPORTANT: See the “Supported configurations topic” in the AssuredSAN Pro 5000 Series Setup Guide for information about base configurations and add-on components.

The supported configuration illustrations in the Setup Guide are provided for visual reference, and serve as a reminder that auto-pool requires certain types of disks to be in certain slots within the enclosure.

TIP: See the “System concepts” topic in the Storage Management Guide for an overview of product feature characteristics pertaining to Pro 5000 Series paged storage systems.

2 Procedures

This chapter provides procedures for replacing FRUs (field-replaceable units), including precautions, removal instructions, installation instructions, and verification of successful installation. Each procedure addresses a specific task. Certain procedures refer to related documentation. See

Related documentation on page 9 for a list of these documents and where to find them online.

Electrostatic discharge

Before you begin any of the procedures, consider the following precautions and preventive measures.

Preventing electrostatic discharge

To prevent electrostatic discharge (ESD) from damaging the system, be aware of the precautions to consider when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

CAUTION: Parts can be damaged by electrostatic discharge. Follow these precautions:

• Avoid hand contact by transporting and storing products in static-safe containers.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-protected workstations.

• Place parts in a static-protected area before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a static-sensitive component or assembly.

• Remove clutter (plastic, vinyl, foam) from the static-protected workstation.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Adhere to the following precautions when handling or installing electrostatic-sensitive parts.

CAUTION: Parts can be damaged by electrostatic discharge. Use proper anti-static protection:

• Keep the replacement FRU in the ESD bag until needed; and when removing a FRU from the enclosure, immediately place it in the ESD bag and anti-static packaging.

• Wear an ESD wrist strap connected by a ground cord to a grounded workstation or unpainted surface of the computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm (± 10 percent) resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

• If an ESD wrist strap is unavailable, touch an unpainted surface of the chassis before handling the component.

• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part. For more information on static electricity or assistance with product installation, contact an authorized reseller.


Replacing chassis FRU components

Chassis FRUs replace a damaged chassis or chassis components. A fully functional chassis requires successful installation of the following components:

• Two controller modules of the same model type (per controller enclosure)

See

Replacing a controller module or expansion module on page 23 for more information.

• All disk drives

See

Replacing a disk drive module on page 29 for more information.

• Two power supply modules of the same type (both AC or both DC)

See

Replacing a power supply module on page 35 for more information.

• Two ear bezels (complementary left and right ear kits)

See

Replacing ear bezels on page 41 for more information

NOTE: Newer product models use an enclosure bezel instead of ear covers. If your model is equipped with a bezel instead of ear covers, see the appropriate illustration for bezel installation and removal:

• See

Figure 3 on page 14 for 2U24 enclosure bezel alignment.

• See


• Two expansion modules of the same model type (per expansion enclosure)

See

Replacing a controller module or expansion module on page 23 for more information.

In addition to the FRUs identified above, replacement procedures are provided to address specific interface protocols and replacement of the enclosure chassis:

• Removal and installation of a Fibre Channel transceiver

See

Replacing a Fibre Channel transceiver on page 44 more information.

• Removal and installation of a 10GbE SFP+ transceiver

See

Replacing a 10GbE SFP+ transceiver on page 46 for more information.

• Removal and installation of a storage enclosure chassis

See

Replacing a storage enclosure chassis on page 46 for more information.

Replacement of chassis FRU components are described within this chapter.

NOTE: AssuredSAN Pro 5000 Series controller enclosures support hot-plug replacement of redundant controller modules, fans, power supplies, and I/O modules. Hot-add of drive enclosures is also supported.

TIP: Many procedures refer to component LEDs and LED statuses. See the AssuredSAN Pro 5000 Series

Setup Guide for descriptions of model-specific front panel and rear panel LEDs.

TIP: Within the AssuredSAN Pro 5000 Series Setup Guide , see “Troubleshooting > Fault isolation methodology” for information about using health icons/values—in addition to using LEDs—for verifying component failure before actually replacing the FRU.

22 Procedures

Replacing a controller module or expansion module

In a dual-controller configuration, controller and expansion modules are hot-swappable, which means you can replace one module without halting I/O to storage-pool components, or powering off the enclosure. In this case, the second module takes over operation of the storage system until you install the new module.

You may need to replace a controller module or an expansion module when:

• The Fault/Service Required LED is illuminated

• Health status reporting in SMC indicates a problem with the module

• Events in SMC indicate a problem with the module

• Troubleshooting indicates a problem with the module

CAUTION: When replacing a Pro 5000 Series controller set supporting AssuredRemote with a Pro 5000

Series controller set that does not support this licensed feature, you must first delete all replication sets before swapping the controller modules. Not doing so will lead to unexpected results, and there is no way to delete replication sets after the installation. See the following for additional information:

• AssuredSAN Pro 5000 Series Storage Management Guide

• AssuredSAN Pro 5000 Series CLI Reference Guide

Before you begin

Removing a controller or expansion module from an operational enclosure significantly changes air flow within the enclosure. Openings must be populated for the enclosure to cool properly. Leave modules in the enclosure until ready to install a replacement. Pro 5000 Series controller enclosures support dual-controller configuration only. Single-controller support is provided only when a controller fails over to its partner controller. A controller module must be installed in each I/O module slot to ensure sufficient airflow through the enclosure during operation.

If replacing both controllers, use SMC to record configuration settings before installing the new controller modules. See

Removing a controller module or expansion module

on page 26, and Installing a controller module or expansion module on page 27 for instructions on installing an additional controller module.

CAUTION: When replacing a controller module, ensure that less than 10 seconds elapse between inserting it into a slot and fully latching it in place. Not doing so might cause the controller to fail. If it is not latched within 10 seconds, remove the controller module from the slot, and repeat the process.

Configuring partner firmware update

In a dual-controller system in which Partner Firmware Update (PFU) is enabled, when you update firmware on one controller, the system automatically updates the partner controller. Disable partner firmware update only if requested by a service technician.

Use SMC or the CLI to change the PFU setting.

Using SMC

NOTE: See AssuredSAN Pro 5000 Series Storage Management Guide , and read the following topics:

• Getting started > Firmware update

• Working in the System topic > Updating firmware > Best practices for firmware update

• Working in the System topic > Updating firmware > Updating controller module firmware

1.

Sign-in to SMC using default user manage

and password

!manage

.

If the default user or password—or both—have been changed for security reasons, enter the secure login credentials instead of the system defaults shown above.


2.

Click in the System panel in the banner and select Update Firmware .

The Update Firmware panel opens. The Update Controller Modules tab shows versions of firmware components that are currently installed in each controller.

3.

Under Partner Firmware Update, check Enabled , then click Set .

4.

Click OK .

Using the CLI

1.

Log-in to the command-line interface using default user manage

and password

!manage

.


2.

To verify that partner firmware upgrade is enabled, run the following command: show advanced-settings

3.

If partner firmware upgrade is disabled, enable it by running the following command: set advanced-settings partner-firmware-upgrade enabled

NOTE: See AssuredSAN Pro 5000 Series CLI Reference Guide for additional information.

Verifying component failure

Select from the following methods to verify component failure:

• Use SMC to check the health icons/values of the system and its components to either ensure that everything is okay, or to drill down to a problem component. SMC uses health icons to show OK,

Degraded, Fault, or Unknown status for the system and its components. If you discover a problem component, follow the actions in its Health Recommendations field to resolve the problem.

• As an alternative to using SMC, you can run the show system command in the CLI to view the health of the system and its components. If any component has a problem, the system health will be

Degraded, Fault, or Unknown. If you discover a problem component, follow the the actions in its Health

Recommendations field to resolve the problem.

• Monitor event notification — With event notification configured and enabled, use SMC to view the event log, or use the CLI to run the show events detail command to see details for events.

• Check Fault/Service Required LED (back of enclosure): Amber = Fault condition

• Check that the FRU OK LED (back of enclosure) is off

Stopping I/O

When troubleshooting disk drive and connectivity faults, ensure you have a current full backup. As an additional data protection precaution, stop all I/O to the affected storage-pool components.

IMPORTANT: Stopping I/O to a storage-pool component is a host-side task, and falls outside the scope of this document.

When on-site, you can verify that there is no I/O activity by briefly monitoring the system LEDs; however, when accessing the storage system remotely, this is not possible. Remotely, you can use the show storage-status

command to determine if input and output has stopped. Perform the steps below:

1.

Using the CLI, run the show storage-status command.

The

Number of Reads and

Number of Writes outputs show the number of these operations that have occurred since the statistic was last requested.

2.

Run the show storage-status command a second time.

This provides you a specific window of time (the interval between requesting the statistics) to determine if data is being written to or read from the storage-pool component.

24 Procedures

3.

If any reads or writes occur during this interval, a host is still reading from or writing to this storage-pool component. Continue to stop IOPS from hosts, and repeat step 1 until the

Number of Reads and

Number of Writes statistics are zero.


Shutting down a controller module

Shutting down the Storage Controller in a controller module ensures that a proper failover sequence is used, which includes stopping all I/O operations and writing any data in write cache to disk. If the

Storage Controller in both controller modules is shut down, hosts cannot access the system’s data. Perform a shut down before you remove a controller module from an enclosure, or before you power off its enclosure for maintenance, repair, or a move.

CAUTION: You can continue to use the CLI when either or both Storage Controllers are shut down, but information shown might be invalid.

Use SMC or the CLI to perform a shut down.

Using SMC

The blue OK to Remove LED (back of enclosure) illuminates to indicate that the controller module can be safely removed.

4.

Illuminate the identification LED of the enclosure that contains the controller module to remove by running the command: set led enclosure 0 on



Removing a controller module or expansion module

IMPORTANT:

• In a single-controller configuration, if you desire to transport CompactFlash to a replacement controller, remove the controller module only after the cache is copied to CompactFlash, which is indicated by the Cache Status LED being off. Transporting of cache must be performed by a qualified service technician. Single-controller support is provided only when a controller fails over to its partner controller. Pro 5000 Series storage enclosures are configured with dual IOMs.

• In a single-controller environment, you must stop I/O and power off the enclosure before replacing the controller module. Single-controller support is provided only when a controller fails over to its partner controller.

• In a dual-controller environment, you may hot-replace a controller module in an operational enclosure, provided you first shut down the faulty controller using either SMC or the CLI.

See CAUTION bullets regarding “electrostatic discharge” and “anti-static protection”

page 21 .

NOTE: Within these procedures, illustrations featuring controller module face plates are generic. They do not show host interface ports, and they pertain to all Pro 5000 Series controller module models. For illustrations of model-specific controller face plates, see the AssuredSAN Pro 5000 Series Setup Guide .

Figure 13 Inserting a controller module

IMPORTANT: In a dual-controller system in which PFU is enabled, when you update firmware on one controller, the system automatically updates the partner controller.

Verifying component operation

After replacing the controller module, verify that the FRU OK LED (rear panel) illuminates green, indicating that the controller has completed initializing, and is online/operating normally. It may take two to five minutes for the replacement controller to become ready. If you are replacing either controller module, and

PFU is enabled, you may need to wait 30 minutes to ensure that the two controllers—with their respective ownership of the storage-pool components—have enough time to fully stabilize.

Use SMC or the CLI to perform a restart only if necessary.

IMPORTANT: See the “Restarting controllers” topic in the Storage Management Guide for more information.

28 Procedures

Using the CLI

If the enclosure’s Unit Locator LED is on, run the following command to turn it off: set led enclosure 0 off

If the Fault/Service Required LED is amber, the controller module has not gone online, and likely failed its self-test. Put the module online by restarting the controller, or by checking the event log for errors.

To restart the Management Controller (A or B), run the following command: restart mc a or restart mc b or restart mc both

To restart the Storage Controller (A or B), run the following command: restart sc a or restart sc b or restart sc both

TIP: See the AssuredSAN Pro 5000 Series Setup Guide for descriptions of model-specific LEDs.

Updating firmware

You can view the current versions of firmware in controller modules, expansion modules, and disks, and you can also install new firmware versions.

TIP: To ensure success of an online update, select a period of low I/O activity. This helps the update complete as quickly as possible and avoids disruptions to hosts and applications due to timeouts.

Attempting to update a storage system that is processing a large I/O-intensive batch job will likely cause hosts to lose connectivity with the storage system.

An enclosure must contain two I/O modules (IOMs) of the same type. Both IOMs should run the same firmware version. Storage systems in a replication set must run the same firmware version. You can update the firmware in each IOM by loading a firmware file obtained from the enclosure vendor.

If the PFU option is enabled, when you update one controller, the system automatically updates the partner controller. If PFU is disabled, after updating firmware on one controller, you must log into the partner controller’s IP address and perform this firmware update on that controller also.

NOTE: If a storage-pool component is quarantined, firmware update is not permitted due to the risk of losing unwritten data that remains in cache for the component volumes. Before you can update firmware, you must resolve the problem that is causing the component to be quarantined. See information about events 172 and 485 in the Event Descriptions Reference Guide.

For best results, the storage system should be in a healthy state before starting firmware update. You can update firmware using SMC or using FTP (File Transfer Protocol). See the Storage Management Guide for more information.

IMPORTANT: Before updating firmware for the first time, see the “Best practices for firmware update” topic in the AssuredSAN Pro 5000 Series Storage Management Guide .

Replacing a disk drive module

A disk drive module consists of a disk in a sled. Disk drive modules are hot-swappable, which means they can be replaced without halting I/O to the storage-pool components, or powering off the enclosure.


Disk drive slot numbers and auto-pool provisioning

SMC provides an automatic pooling feature (known as auto-pool) for provisioning disks in selected, properly configured enclosures for use in tiers in storage pools, as spares, or as SSD read cache. During first-time configuration of a new system, auto-pool enables you to quickly provision the storage in all connected enclosures so that you can start creating volumes and mapping them to hosts. Over the life of the system, auto-pool enables you to add disks or enclosures to provide additional storage for existing storage pools. Auto-pool also enables you to remove storage from available storage in the system; for example, an enclosure of disks or a storage pool and all of its disks. You can also upgrade storage by removing individual components or tiers per enclosure; for example, you can upgrade from read cache to full SSD.

TIP: See the “System concepts” topic in the Storage Management Guide for an overview of product feature characteristics pertaining to Pro 5000 Series paged storage systems.

The following rules apply to auto-pool:

• The storage system must include a minimum of 48 disks (storage enclosures must be fully-populated).

• In an enclosure, all disks of the same type/speed must have the same capacity—measured in blocks.

• The storage system must include two spares per disk type for RAID-6 and RAID-10 components.

• You must have a minimum of 500 GB in your storage pool — not including spares or read cache.

• For provisioning to start, all disks must be in a good state. If the system detects a bad disk, auto-pool will not proceed. Spares cannot be used while storage pools are being provisioned.

• A storage-pool component will be constructed with disks that are of the same type/speed and have the same capacity, and are in the same enclosure. A component cannot span enclosures.

• Storage pool components comprised of disks in 24-disk enclosures are created in symmetrical sets that are balanced between the two storage pools. For provisioning to start, there must be enough disks available to create all components in a set. Components comprised of disks in a 12-disk enclosure can be assigned to either pool (either automatically or manually).

• If auto-pool fails for an enclosure, all changes for that enclosure are discarded.

Auto-pool requires certain types of disks to be in specific slots. Table 6 below shows a legend for the

following figures:

•

Figure 14 on page 31 (Disk slot configuration options for 24-drive enclosures)

•

Figure 15 on page 31 (Disk slot configuration options for 12-drive enclosures)

These figures show supported configuration options for disks used in Pro 5000 Series enclosures, and how those disks will be provisioned by auto-pool with regard to slot affinity (certain types of disks must reside in specific slots, and these locations cannot change).

See Figure 14 on page 31. For example, controller enclosure option 1 shows that the enterprise disks in

slots 0—19 will be provisioned for use in storage pools A and B in the Standard tier, one SSD will be configured as SSD read cache for each storage pool, and the enterprise SAS disks in slots 22—23 will be spares for the Standard tier.

Before you begin

CAUTION: Removing a disk drive module impacts the airflow and cooling ability of the enclosure. If the internal temperature exceeds acceptable limits, the enclosure may overheat and automatically shut down or restart. To avoid potential overheating, wait 20 seconds to allow the internal disks to stop spinning, then insert the new disk drive module.


page 21 .


Before replacing a disk, perform the following steps to ensure that you have correctly identified the module requiring removal and replacement.

CAUTION: Failure to identify the correct disk drive module could result in data loss if the wrong disk is removed from the enclosure. If your enclosure has a bezel, remove it to view disk LEDs. Alternatively, you can observe disk component health via SMC.

When a disk drive fault occurs, the failed disk’s fault indicator LED, located on the enclosure’s front panel, illuminates solid amber (see the AssuredSAN Pro 5000 Series Setup Guide for a description of LEDs and disk drive slot numbering for your enclosure). You can determine from visual inspection which disk in the enclosure is experiencing a fault/failure using the fault LED for your disk type.

NOTE: Newer product models use an enclosure bezel instead of ear covers. If your model is equipped with a bezel instead of ear covers, see the appropriate illustration for bezel installation and removal:

• See


• See


Alternatively, you can observe disk component health using management interfaces to verify component failure or component operation (see

Using management interfaces on page 50 for more information).

Replacing a power supply module

This section provides procedures for replacing a failed AC or DC power supply module, also referred to as a power supply unit (PSU). Illustrations in power supply module replacement procedures show rear panel views of the enclosure, and PSUs are properly aligned for insertion into the rear panel of the enclosure.

CAUTION: Power supply FRU replacement activities can cause enclosure cables to disconnect and disks to go offline.

When replacing a power supply FRU, you might accidentally disconnect cables, causing disks to go offline. As a precaution—before installing or replacing a FRU—you should stop I/O to all storage-pool components. If stopping I/O is not possible, the next best action is to defer FRU replacement until such time as it is possible to stop all I/O. If immediate replacement is necessary during I/O, ensure that all cables are securely fastened, and proceed with great caution as you replace the power supply FRU within the controller enclosure. Be very careful if moving a cabled/operational enclosure during the FRU replacement process.

A single PSU is sufficient to maintain operation of the enclosure. You need not halt operations and completely power-off the enclosure when replacing only one PSU; however, a complete shutdown is required if replacing both power supply units.

TIP: See

Table 7 on page 36 for additional information about power supply faults and recommended

actions.


Before you begin

CAUTION: Removing a power supply unit significantly disrupts the enclosure’s airflow. Do not remove the

PSU until you have received the replacement module.


page 21 .


When either a fan or power supply component fails, SMC provides notification; faults are recorded in the event log; and the PSU’s status LED color changes to amber to indicate a fault condition.

command will output health status for fans in the specified enclosure.

• Ensure that the power supply modules are properly seated and secured within their slots.

• Ensure that no slots are left open for more than two minutes. If you must replace the FRU, leave the old module in place until the replacement arrives to maintain optimal airflow and avoid overheating.

• Verify that the power supply module is powered on.

If your power supply module has a power switch, verify that it is switched on.

• Verify that the power cables are securely attached to the power supply module and the appropriate power source.

• Replace the FRU if necessary.

Same as above.

Replace the power supply module FRU.

Power supply units

IMPORTANT: Newer AC power supply units do not have power switches. These PSUs power on when connected to a power source, and power off when disconnected.

Power cycling procedures vary according to the type of power supply included with the enclosure. For controller and expansion enclosures configured with AC PSUs that do not have power switches, refer to the procedure described under

AC PSU on page 37. For procedures pertaining to a) enclosures configured

with DC PSUs, or b) previously installed expansion enclosures featuring power switches, see

DC and AC

PSUs with power switch on page 37.

36 Procedures

AC PSU

Enclosures configured with AC PSUs that do not have a power switch rely on the power cord for power cycling. Connecting the cord from the PSU power cord connector to the appropriate power source facilitates power on; whereas disconnecting the cord from the power source facilitates power off.

on page 41 (2U24 chassis), Figure 25 on page 42, and Figure 26

(2U12 chassis) when installing the ear bezel sub-assemblies.

1.

Verify that the enclosure is powered off.

2.

Install the LED circuit board: a.

Insert the mounting pins into the though holes in the LED circuit board and mounting flange.

b.

Thread the hexagonal nuts onto the inserted pins, and turn the nuts clockwise to tighten.

3.

Gently slip the ear cover over onto the push-fit mounting ball studs, taking care to guide the LED indicators through the cover’s through holes.

NOTE: Newer product models use an enclosure bezel instead of ear covers. If your model is equipped with a bezel instead of ear covers, see the appropriate illustration for bezel installation:

• See

Figure 3 on page 14 for reduced-depth 2U24 enclosure bezel installation.

• See

Figure 7 on page 18 for standard-depth 2U12 enclosure bezel installation.

4.

Power on the enclosure.

TIP: See the AssuredSAN Pro 5000 Series Setup Guide for descriptions of front panel LEDs.


Enclosure status LEDs are located on the front of the controller enclosure. During normal operation, the FRU

OK and Temperature Fault LEDs are green, and the other status LEDs located on the right ear are off.


Replacing a Fibre Channel transceiver

This section provides steps for replacing a small form-factor pluggable (SFP transceiver) connector used in a

Fibre Channel (FC) controller module host port. An example SFP connector is shown below. It is pictorially-oriented to align for insertion into the FC host interface port, such that the connector is flush with the IOM face plate on the enclosure rear panel.

Figure 27 Sample SFP connector

NOTE: See the “5720 controller module — rear panel components” topic within the Setup Guide for an illustration showing an SFP installed within the IOM.

Before you begin

CAUTION: Mishandling fibre-optic cables can degrade performance. Do not twist, fold, pinch, or step on fibre-optic cables. Do not bend them tighter than a 2-inch radius.


page 21 .

CAUTION: To prevent potential loss of access to data, be sure to identify the correct cable and SFP connector for subsequent removal.


Transceivers are part of a data path that includes multiple components, such as the transceiver, a cable, another SFP, and an HBA (host bus adapter). A reported fault can be caused by any component in the data path. To identify the location of the fault, check the Link Status and Activity LEDs on the controller enclosure and server. Also, check the cable for kinks, crimping or other possible damage.

TIP: See the AssuredSAN Pro 5000 Series Setup Guide for descriptions of rear panel LEDs.

Removing an SFP module

Perform the following procedure to remove an SFP connector. When removing an FC SFP that has previously limited the port speed—and replacing it with a higher-rated SFP—it is possible, though rare, that auto-negotiation will not enable the higher port speed. Rebooting the array or the host resolves the problem.

1.

Disconnect the fibre-optic interface cable by squeezing the end of the cable connector.

If the SFP does not have a cable, it should have a plug (retained from installation).

3.

Grasp the SFP between your thumb and index finger, and carefully remove it from the controller module.

Installing an SFP module

Perform the following procedure to install an SFP connector.

1.

To connect to an empty port, slide the SFP connector into the port until it locks into place.

If the SFP has a plug, remove it before sliding the connector into the FC port. Retain the plug.

2.

Flip the actuator down.

View the Link Status and Link Activity LEDs on the controller module face plate. A blinking LED indicates that no link is detected. Also check the link status and link activity LEDs on the host.

Replacing a 10GbE SFP+ transceiver

This section provides steps for removing and replacing a small form-factor pluggable plus (SFP+ transceiver) connector used in an Internet SCSI (iSCSI) controller host port. SFP+ connectors are similar in appearance to SFP connectors. These transceivers enable 10GbE equipment designs with high port density, based on electrical and mechanical enhancements to SFP specifications developed by the Small

Form Factor (SFF) Committee.

Removing and replacing an SFP+ consists of the same basic steps described for removing and replacing an SFP in the preceding section. This procedure refers to the preceding

Replacing a Fibre Channel transceiver

instructions. When reviewing the procedure as it pertains to the 10Gb iSCSI host ports, note that your particular cables may be either copper or fibre-optic for the SFP+, depending upon how your system was initially configured, and the SFP+ option used.

Table 9 Removing and replacing a 10GbE SFP+ transceiver

To accomplish this sequential process

1.

Remove SFP+ connector.

2.

Install the replacement SFP+ connector.

3.

Verify proper operation for the removed and reinstalled component.

Replacing a storage enclosure chassis

The controller enclosure or expansion enclosure chassis replacement procedure replaces a damaged chassis FRU, which consists of the structural support metal, the exterior sheet metal housing, and the assembled/installed midplane. The procedure includes removing all FRU components from a damaged chassis and installing them in a replacement chassis.

46 Procedures

NOTE: AssuredSAN Pro 5000 Series storage enclosures using 2U24 or 2U12 chassis are described in

FRUs addressing 24-drive enclosures on page 12 and

FRUs addressing 12-drive enclosures on page 16.

Whether your controller enclosure product is a 2U24 or 2U12 model, a fully functional replacement chassis requires the successful removal and installation of the following components:

• All disk drive modules

• Two ear bezels (for left and right ears)

Product models may use an enclosure bezel instead of left and right ear covers

• Two power supply units of the same type (both AC or both DC)

• One or two I/O modules (of the same model type)

Certain models also require the successful removal and installation of the following components:

• Fibre Channel transceiver (SFP for 5720 models)

• 10GbE SFP+ transceiver (SFP+ option for 5420 models)

This procedure makes extensive use of the FRU component procedures described elsewhere in Chapter 2.

Perform this procedure by following the step-by-step process described below.

Before you begin

CAUTION: Do not remove the enclosure until you have received the replacement enclosure.


page 21 .

1.

Schedule down time that will allow for shutdown; sixty minutes of replacement work; and restart.

2.

Verify the existence of a known/good backup of the system.

3.

Record system settings for future use.

4.

Label all cables.

5.

Prepare a suitable static-protected work environment to accommodate chassis replacement.


The controller enclosure FRU includes the enclosure’s metal housing and the midplane that connects I/O modules, disk drive modules, and power supply modules. This FRU replaces an enclosure that has been damaged, or whose midplane has been damaged.

Often, a damaged midplane will appear as though an I/O module has failed. If you replace an IOM, and it does not remedy the fault, you may need to replace the enclosure.

Alternatively, you can observe enclosure health (front panel and rear panel) using management interfaces

to verify enclosure/component failure or enclosure/component operation (see Using management interfaces on page 50 for more information).

Preparing to remove a damaged storage enclosure chassis

Since you are removing and replacing an entire storage enclosure, neither the hot-swap capability that applies to replacing individual redundant FRUs in an operational storage enclosure, nor the hot-add of a drive enclosure to an operational storage system, apply to this procedure.

1.

Stop all I/O from hosts to the system. See

Stopping I/O on page 24.

2.

Shut down the controllers. See Shutting down a controller module on page 25.

3.

Power off the system (controller enclosure first; expansion enclosure(s) next). See

Power supply units on page 36, and refer to the power cycling procedures pertaining to your enclosure’s power supply

modules.

3.

Maintaining a level position, carefully slide the enclosure chassis from the rack.

4.

Place the chassis on a work surface near the replacement enclosure chassis, the removed disk drive modules, ear bezel components, and screws.

5.

Remove the side bracket from each side of the damaged enclosure chassis, and retain these rackmount items with the other components for future use.

Installing the replacement storage enclosure in the rack

This section provides a procedure for installing the replacement enclosure in its rack location.

CAUTION: It is recommended that all disk drive modules be removed before lifting the enclosure. If this is not possible, two people are required to move the enclosure. See

Removing a disk drive module on page 32.

NOTE: Refer to Rackmount Bracket Kit Installation or 2-Post Rackmount Bracket Kit Installation for the correct procedure and mounting hardware.

1.

Attach side brackets (standard rackmount installation) or main brackets (2-post rackmount installation) on the replacement enclosure chassis.

2.

Support the bottom of the enclosure chassis. Carefully lift/align the chassis and while maintaining a level position for the enclosure, slide it into the rack.

3.

Using the appropriate mounting hardware, secure the enclosure chassis to the rack.

4.

Install the ear bezels. See Installing ear bezel components on page 43.

5.

Using the applicable retaining screws, secure the front and rear or the enclosure chassis to the rack and rails.

Completing the process

This section provides a procedure for ensuring that the FRU components installed in the replacement controller enclosure chassis function properly.

1.

Reconnect data cables between devices, as needed, to return to the original cabling configuration:

• Between cascaded enclosures.

• Between the controller and peripheral or SAN devices.

• Between the controller enclosure and the host.

2.

Reconnect power cables to the controller enclosure. See

Connecting a power cable on page 40.

3.

Turn on the power switch to power supply modules if they are equipped with power switches.

NOTE: For powering-on AC PSUs with or without a power switch, and DC and AC PSUs with a power switch, see

Power supply units on page 36.



1.

Restart system devices in the following sequence. Allow time for each device to complete its Power On

Self Tests (POST) before proceeding: a.

Expansion enclosure(s) b.

Controller enclosure c.

Host (if powered down for maintenance)

2.

Perform a rescan to force a fresh discovery of all expansion enclosures connected to the controller enclosure. This step clears the internal SAS layout information, reassigns enclosure IDs, and ensures that the enclosures are displayed in the proper order. Use either the CLI or SMC to perform the rescan:

To perform a rescan using the CLI, enter the following command: rescan

To perform a rescan using SMC, follow the substeps below: a.

Verify that the controllers are operating normally.

b.

Do one of the following:

• Point to the System tab and select Rescan Disk Channels .

• In the System topic, select Action > Rescan Disk Channels .

The Rescan Disk Channel panel opens.

c.

Click Rescan .

See “Correcting enclosure IDs” in the Setup Guide for more information.

Using LEDs

View LEDs on the front and rear of the enclosure (see “LED descriptions” within the AssuredSAN Pro 5000

Series Setup Guide for more information).

Verify front panel LEDs:

• Verify that the Enclosure ID LED (located on the left ear) is illuminated green.

• Verify that the FRU OK and Temperature Fault LEDs are illuminated green, and that the Fault/Service

Required LED is off (all three LEDs are located on the right ear).

• For LFF disks, verify that the Power/Activity/Fault LED (bottom LED on front of disk) is illuminated green or blinking green (If your product model has an enclosure bezel, remove it to view disk LEDs).

• For SFF disks, verify that the Power/Activity LED (left LED on front of disk) is illuminated green or blinking green (If your product model has an enclosure bezel, remove it to view disk LEDs).

Verify rear panel LEDs:

• Verify that each power supply module’s Input Source Power Good LED (top LED on PSU) is illuminated green.

• Verify that the FRU OK LED on each IOM face plate is illuminated green, indicating that the module has completed initializing, and is online.

Using management interfaces

In addition to viewing LEDs as described above, you can use management interfaces to monitor the health status of the system and its components, provided you have configured and provisioned the system (see

“Getting Started” within the AssuredSAN Pro 5000 Series Storage Management Guide for more information).

Select from the following methods to verify component operation:

• Use SMC to check the health icons/values of the system and its components to either ensure that everything is okay, or to drill down to a problem component. SMC uses health icons to show OK,

Degraded, Fault, or Unknown status for the system and its components. If you discover a problem component, follow the actions in its Health Recommendations field to resolve the problem.

• As an alternative to using SMC, you can run the show system command in the CLI to view the health of the system and its components. If any component has a problem, the system health will be

50 Procedures

Degraded, Fault, or Unknown. If you discover a problem component, follow the actions in its Health

Recommendations field to resolve the problem.

• Monitor event notification — With event notification configured and enabled, you can view event logs to monitor the health of the system and its components. If a message tells you to check whether an event has been logged, or to view information about an event in the log, you can do so using either SMC or the CLI. Using SMC, you would view the event log and then hover over the event message to see detail about that event. Using the CLI, you would run the show events detail command (with additional parameters to filter the output) to see the detail for an event (see “Alphabetical list of commands > show events” within the AssuredSAN Pro 5000 Series CLI Reference Guide for more information about command syntax and parameters).
