Chapter 1 Introduction

About the RAID Storage Chassis

This RAID Storage provides a compact, high-capacity, high-availability source of disk storage for the Profile. A single RAID Storage chassis offers a large capacity of high-availability disk storage in as many as 20 disk modules that can individually be replaced while the system is powered up.

Two models are available, the PRS 200 and the PRS 200A. The PRS200A offers increased storage time through the use of 9-GByte hard disks (the PRS200 uses

4-GByte hard disks).

RAID Storage Components

RAID Storage Components

The RAID Storage chassis contains the components listed below.

• Two storage-control processors (SP).

• 10, 15, or 20 disk drive modules.

• One fan module.

• Three voltage semi-regulated converters (VSCs) power supplies

The SPs, disk modules, fan module, and VSCs in the RAID Storage chassis are

customer-replaceable units (CRUs), which you can install or replace yourself.

The following illustration shows the location of the RAID’s CRUs, which also include the SCSI bus cable, SCSI terminator plug, power cord, and the optional asynchronous cables. In addition to the CRUs, the RAID Storage chassis contains field-replaceable units (FRUs). Only qualified service personnel should replace a

FRU.

Latch

Bezel

The SP consists of a printed circuit board with two or four memory modules (SIMMs) and a bezel with status lights, and latches to secure the SP in place. The memory modules provide 32 Mbytes of SP memory. The SP uses 4Mbytes of this memory for system buffers. The remaining memory is available for system use.

Two status lights on the SP indicate the following:

Ready light (green) — Lights while the SP is powered on and operating normally.

Service light (amber) — Lights when the SP is not working properly.

The SPs are visible when you swing the fan module down from the back of the RAID

Storage chassis.

The SP processes data written to or read from the disk drive modules, and controls the disk modules in the storage chassis through a synchronous SCSI-2 bus. It has four internal SCSI-2 buses, each supporting five disk drive modules (1 array) for a total of

20 disk drive modules (4 arrays). The Disk Array Storage System Manager

(dassmgr) uses an RS-232 connection to the RAID Storage chassis to communicate with an SP. Using the dassmgr, you can set up RAID Storage memory, bind disk modules into logical units (LUNs), update the RAID Storage Licensed Internal Code, and check RAID Storage status.

IMPORTANT You should never attempt to replace any of the SP’s components, except the memory modules.

A disk drive module, also called a disk module, consists of a disk drive, a power regulator board, internal cabling, and a plastic carrier. The carrier has a handle and guides for inserting and holding the module in the RAID Storage chassis. A label attached to the carrier’s side shows the drive module’s model number and capacity.

Three status lights on the module indicate the following:

Ready light (green) — Lights while the disk drive module is powered up and ready for use.

Busy light (green) — Lights while the drive is in use; for example, during formatting or user I/O operations.

Fault light (amber) — Lights when the module is shut down by the SP because the module failed. Also lights after you replace the drive, while the replacement drive spins up to speed.

You can remove or install any one module at a time within an array group either while the storage chassis is running or in the idle mode (not running). (You will have to wait for data regeneration before the replaced module is available.)You should never open a disk drive module or attempt to replace any of its internal components.

Voltage Semi-regulated Converters (VSCs)

Replace light

(amber)

Ready light

(green)

The VSCs are power supplies that convert the installation site’s ac line voltage to the

48, 24, and 18Vdc required to power the modules in the RAID Storage chassis. The chassis contains three VSCs for high-availability operation.

Two status lights on each VSC indicate the following:

Ready light (green) — Lights while VSC is operating normally.

Replace light (amber) — Lights when the SP determines that the VSC has failed.

The VSCs are visible when you swing the fan module down on the back of the RAID

Storage chassis.

You can remove or install a VSC while the storage chassis is running.

If a VSC fails, replace it as quickly as possible. With three VSCs, if one of them fails, the RAID Storage continues to operate but you still should replace the failed VSC as soon as possible to restore high-availability operation. Failure to replace the VSC could cause the RAID Storage chassis to shut down if either the fan module or another

VSC fails. You should never open a VSC or attempt to replace any of its internal components.

(amber)

Lock

The RAID Storage chassis uses a single fan module, also called a fan pack, that attaches to the back of the chassis. The fan module contains six high-capacity, multiple speed fans, and a control/monitor board.

One status light on the fan module indicates the following:

Replace light (amber) — Lights when a fan in the module is not working.

For high-availability operation, if a fan stops working, the remaining five fans speed up to maintain air flow. The Replace light turns on to indicate that you must replace the fan module as soon as possible.

The fan module is mounted on hinges so you can swing it down away from the chassis. A mechanical lock and magnetic catches hold the fan module closed.

NOTE: If the fan module remains open for more than approximately 2 minutes, the storage chassis automatically shuts down to prevent overheating.

You can remove a fan module while the storage chassis is running. You should never open the module or attempt to replace any of its internal components. If one of the fans in the module fails, replace the fan module as quickly as possible to maintain high-availability operation. Failure to replace the module could cause the RAID

Storage to shut down if either a VSC module or another fan fails.

The Profile internal drives can not be used when a RAID unit is connected. To disable the Profile internal disk drives and enable the RAID Storage, refer to your Profile

User Manual.

Removal of Profile Internal Disk Drives

NOTE: Only qualified service personnel should perform the following procedure.

If you want to use the Profile internal drives removed from a system with RAID

Storage, and are sure you will not be using that Profile without RAID Storage, you can remove the internal disk drives. Two procedures follow, one for the PDR 100 and one for the PDR200.

Removing PDR100 Internal Drives

To remove the internal disk drives from the PDR100, perform the following procedure:

1. Turn all power to the Profile Off.

NOTE: You should NOT discard any hardware or cables.

2. Refer to your Profile Service Manual to remove the top cover from the Profile.

3. Refer to your Profile Service Manual to remove the SCSI cable(s) from the Profile.

(If you have a 2-channel Profile there will be a SCSI A cable only. If you have a

4-channel Profile there will be both a SCSI A and a SCSI B cable.)

4. Refer to your Profile Service Manual to remove the Hard Disk Carrier Tray from the Profile chassis.

5. Refer to your Profile Service Manual to remove the hard disk drives from the tray.

(There will be 4 hard disk drives if you have a 2-channel Profile and 8 hard disk drives if you have a 4-channel Profile.)

6. Refer to your Profile Service Manual to re-install the empty Hard Disk Carrier Tray into the Profile chassis.

7. Use cable ties to anchor the loose hard disk drive cable(s) to the inner top edge of the Hard Disk Carrier Tray.

Connection to the Profile

The RAID Storage chassis connects to the Profile through a wide SCSI-2 differential bus. This SCSI bus connection allows the Profile to communicate with the disks in the RAID Storage chassis. Also, you can administer, configure, and monitor the

RAID Storage chassis using dassmgr through an asynchronous communications connection between its asynchronous (console) port and the Profile’s RS-232 port.

The procedures in this chapter assume the following:

• You have all the cables and cable adapters that you need.

• If necessary, someone has installed and/or updated the Profile software.

• The Profile operating system is shutdown, and the Profile it turned off.

• If the Profile has a PDX Disk Expansion unit, it must be removed from the system.

You can not connect both a RAID and a PDX Disk Expansion unit to the same

Profile.

Connecting Asynchronous (console) Cables

To use dassmgr to bind disk modules into logical units, set up storage chassis caching, and monitor storage chassis operation, you must connect the console SP port for each SP in a storage chassis to an asynchronous port of the Profile.

1. Attach a 25-pin female-to-9-pin female null modem cable to the Profile’s RS-232 connector in the upper right corner on the Profile’s rear panel.

Setting SP SCSI IDs

Each SP connected to the same SCSI bus requires a unique SCSI ID number (that is, a number that is not used by any other device on the bus). The back of the storage chassis, see the following illustration, has two SCSI ID switch packs. Each switch pack has four switches (ID0-ID3). One switch pack sets the SCSI ID for SP A, and the other sets the SCSI ID for SPB. Set the SCSI ID switches for both SP A and SPB to 8, if this ID is unused. If it is used, set their SCSI IDs to the next highest unused ID number.

NOTE: If you wish to configure your RAID Storage units as two external file systems, the RAID Storage units in the second file system must be set to SCSI ID s

12 and higher. Refer to the Disk Utility section of the Profile User manual for information on how to create file systems.

The Profile will support two separate external file systems. The RAID Storage chassis is an external attachment which can be assigned SCSI IDs 8 through 15.

If the RAID units are configured as two external file systems, the first unit or pair of units of the second file system must be set to SCSI ID 12. If only a single RAID is to be used, it should be assigned the lowest SCSI ID available. See the following two examples.

EXAMPLE 1: Two RAIDs daisy-chained to a Profile with a single external SCSI bus would have SCSI IDs 8 & 9.

EXAMPLE 2: Six RAIDs attached to a Profile with two external SCSI buses

(three daisy-chained RAIDs to each bus) would have SCSI IDs 8, 9, & 10 on each

bus.

NOTE: RAID units must be attached symmetrically to the two buses (that is, the same number of RAIDs on each bus with the same number of disk modules in each chain).

RAID Instructions

Configuring and Managing the RAID

Configuring and Managing the RAID

To set up the RAID Storage chassis, you need to set the storage chassis date, time, and optional password protection.

You perform these tasks using the Disk Array Storage System Manager

(DASSMGR).

Running DASSMGR

You can run DASSMGR from a bootable diskette, or install it on the Profile system hard disk and run it from that disk.

Before You Begin

Before you can run DASSMGR, someone must have performed these tasks:

• Connected the storage chassis to the Profile.

• Connected the RS-232 port on the storage chassis to a spare COM port on the

Profile. See “Connecting Asynchronous (console) Cables” on page 2-10..

Starting DASSMGR

To start DASSMGR:

1. Power up the storage chassis.

IMPORTANT

Make sure you specify the correct communications port when you issue the DASSMGR command in the next step. Specifying the wrong port may cause problems with the device connected to that port.

2. Run DASSMGR using the command DASSMGR x, where x represents the communication port. For example, to run DASSMGR with communication port 2, at the MS-DOS command prompt enter

DASSMGR 2

modules A1, B1, C1, D1, and E1. The status of each disk module in LUN 0 is ENA, and in LUN 1 is BIN (binding).

* Ten empty slots are also shown. The empty module slots include modules A2, B2, C2, D2, E2, A3, B3, C3, D3, and E3.

Heartbeat — Following the screen title (Presentation Utility) is an asterisk in parentheses (*). This asterisk indicates the heartbeat status of the SP. It should blink every several seconds to indicate that the SP is functioning. If it does not appear to blink, the SP may not be working. Try pressing Ctrl-Q. If the asterisk still does not blink, the SP requires service.

Disk status — In the grid itself, the blocks of boxes identify slots for disk modules in the chassis. Associated with each slot is an identifier (ID) based on the slot’s position in the chassis. You identify a disk module by its disk ID, which is the ID of the slot containing it. A disk ID is made up of a letter indicating the SCSI bus for the slot and a number indicating the slot’s position on the SCSI bus. The disk IDs for the storage chassis are

For each slot that contains a disk module, the box shows a three letter status code. The table on the next page lists the status codes. If a disk module is not bound, the displayed code is UNB with two asterisks (**). For a bound module, the box shows the code and logical unit number (of the RAID group, individual unit, or hot spare) to which the module is bound. A box without text indicates an empty slot, that is, one not containing a disk module.

Reconfiguring a Storage System

Reconfiguring a Storage System

The following explains how to reconfigure a storage chassis in these ways:

• Changing physical disk configurations

• Changing physical disk unit parameters

• Updating Licensed Internal Code

The procedures below assume you are using DASSMGR to reconfigure the storage chassis.

Changing Physical Disk Configurations

As your organization’s needs change, you may want to add disk modules to any unused compartments (slots).

Adding Disk Modules and Creating New Logical Units

If the storage chassis has unused disk module slots, you can increase the available storage capacity by installing additional disk modules, as described in Replacing or

Adding a Disk Module on page 3-18. Normal processing can continue while you install disk modules.

IMPORTANT

All disk modules in any one storage chassis and in any storage chassis in chains must be of the same capacity.

We recommend that you add disk modules in groups of five to the slots in the following order:

A0, B0, C0, D0, E0,

A1, B1, C1, D1, E1,

A2, B2, C2, D2, E2,

A3, B3, C3, D3, E3

To add a physical disk unit:

1. Update the worksheets that define your configuration.

2. Remove the disk filler modules and install the additional disk modules. Refer to

Upgrade and Repair of a Storage System on page 3-14 for instructions.

3. Bind the newly installed disk modules into the desired logical unit. See “Binding

Disk Modules as a Logical Unit” on page 3-6.

4. Refer to your Profile User Manual to make the newly created physical disks available to the Profile operating system.

RAID Instructions

3-5


Binding Disk Modules as a Logical Unit

You must bind exactly five disk modules. You can bind one less module per group than you will eventually use by selecting a box representing an empty slot. However, the group operates in a degraded mode until a module is installed in the empty slot, and the storage chassis integrates it into the group. You can select the modules in any order.

To bind disk modules into a logical unit:

1. From the GridMgr Main Menu, choose the Bind Logical Units option.

The program displays the grid for the RAID-3 option. The grid depicts the drive modules in the storage chassis, and highlights the first group of disk modules available to be bound (UNB). The figure below shows a sample grid.

4. Enter 0, 1, 2, or 3 (hex) depending on which you are binding (see the sample grid above). (Note that for Profile, only LUNs 0 - 3 are valid).

5. Press Enter. The following option appears immediately below the first option.

Maximum rebuild time <hours> [default]

Maximum rebuild time — The maximum rebuild time is the approximate amount of time that the storage chassis allots to reconstruct the data on a new disk module that replaces a failed disk module in a logical unit. The actual rebuild time may be longer or shorter. You can change the rebuild time with DASSMGR later without damaging the information stored on the disk.

6. Press 24 hours and then press Enter.

Bind Options

Logical unit number (0-1F hex)? [1]

Maximum rebuild time <hours>? [8]

7. To accept, type Y, and press Enter. To reject, just press Enter.

If you confirm, you are asked whether or not to bind the modules. If you reject, the cursor returns to the Logical unit number prompt, so you can change any values you want.

8. In response to the question, type Y and press Enter if you want to bind the group as specified; otherwise, type N and press Enter.

If you type N, the original grid appears so you can return to Step 4 and start selecting modules again.

If you typed Y, the program changes the UNB to BIN for a RAID group or individual unit, and starts creating the logical unit you specified. The time the SP takes to complete the binding operation depends on the size and number of disk

modules being bound. Generally, binding takes about 30 minutes to initialize data on 4-Gbyte modules.

As soon as the binding operation starts, it changes the unbound module symbol

(**) to logical unit number you specified for each module being bound.

While a unit is binding, you can proceed to bind another unit by repeating the procedure. After you have selected the last LUN and started it binding you will get an error message stating there are no more modules available to bind. This is normal. Press ^ to get back to Grid Manager and view the binding progress. When the binding is finished, the disk status changes from BIN to ENA.

IMPORTANT

To determine the progress of the binding procedure, highlight one of the group’s disk modules and press Enter. The Performance statistics screen displays a percentage complete figure. For more information, see

Performance statistics screen later in this chapter.

9. Reboot the RAID Storage chassis.

Unbinding a Physical Disk Unit

You use DASSMGR to unbind a physical disk unit. Unlike binding, unbinding takes only a few moments.

CAUTION: Unbinding a physical disk unit effectively erases all information on the physical disk unit. You cannot use any unbound module until you bind it into a logical unit again, make the unit available to the operating system, and create a volume on the unit. Additionally, all information in the Profile partition is lost. The only time one would unbind is in the case of a double faulted LUN.

To unbind a physical disk unit:

1. From the GridMgr Main Menu, choose the Unbind Logical Units option.

2. After reading the advisory screen that appears, press Enter.

The grid appears with all disk modules of the first-bound logical unit (unit 0) highlighted. The figure that follows shows a sample grid.

4. Press the Enter key to select the highlighted physical disk unit for unbinding.

A screen appears warning you that unbinding destroys all data on the physical disk unit, and then asks if you want to unbind this physical disk unit.

5. If you want to unbind the physical disk unit, type Y and press Enter; otherwise, cancel the unbind operation by typing N.

The SP unbinds the physical disk. For each module, the status changes from ENA or RDY to UNB and the unit number changes to the unbound module symbol (**).

If you want to unbind another physical disk, repeat the procedure.

Changing Physical Disk Unit Parameters

You can change the Rebuild time for a physical disk unit after it is bound:

Changing the Rebuild Time

The rebuild time is the amount of time that the storage chassis allots to reconstruct the data on a new disk module that replaces a failed disk module in a logical unit. It applies to all RAID physical disk units. The time you specify determines the amount of resource the SP devotes to rebuilding instead of to normal I/O activity.

The default time of 24 hours is adequate for most situations. A rebuild time of less than 24 hours rebuilds the disk more quickly, but degrades response time. A rebuild time of 0 hours rebuilds the disk module as quickly as possible, but degrades response time significantly. If your site requires fast response time and you want to minimize degradation to normal I/O activity, you can extend the rebuilding process over a longer period of time.

NOTE: The actual rebuild time can differ significantly from the time you specify, especially between a 2-channel Profile and a 4-channel Profile.

Updating Licensed Internal Code

The Licensed Internal Code (LIC) diskette may also include an update to the SP programmable read-only memory (PROM) code. When you install Licensed Internal

Code, the SP tries to copy it to reserved areas outside operating system control on four disk modules, which are called the database disks. The database disk modules are A0,

B0, C0, and A3. (See the figure below.)

For the LIC installation to succeed, at least two of the database disk modules must be on-line, and ideally, all of them should be on-line. A disk module is on-line if it is fully powered up and not faulted; that is, if it has a status code on the Presentation

Utility screen and this code is not

POW

or

OFF

. Having multiple copies of code offers higher availability if a disk module fails.

Upgrade and Repair of a Storage System

You can upgrade your storage chassis by adding optional modules that are customer-replaceable units (CRUs). You can repair a storage chassis by replacing faulty CRUs, and you can add or replace the following CRUs while the storage chassis is powered up:

• Disk modules

• Storage control processors (SPs) and their memory modules (SIMMs)

• Voltage semi-regulated converters (VSCs)

• Fan module

You can also replace the external SCSI bus cables, SCSI terminator plugs, power cord, and optional asynchronous cables. If you do not know how to connect the cables and terminator plugs, refer to Chapter 2, Installation, for information on where and how to connect them.

In addition to the CRUs, the disk-array storage chassis contains field-replaceable units (FRUs). Only qualified field personnel should replace a FRU. See Appendix B for ordering information.

Handling CRUs

Handling CRUs

The following describes the precautions that you must take and the general procedures you must follow when removing, installing, and storing CRUs.

Avoiding Electrostatic Discharge (ESD) Damage

The cover(s) and filler panel(s) installed on the equipment protect the electronic circuits inside the equipment from electrostatic discharge (ESD) damage. However, when you remove these covers and filler panels to replace or install subassemblies, you can inadvertently damage the sensitive electronic circuits in the equipment by simply touching them. Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, running a humidifier in the work area will help decrease the risk of ESD damage. You must follow the procedures below to prevent damage to the equipment.

CAUTION: Read and understand the following instructions before you remove the cover(s) or panel(s) from the equipment.

• Provide enough room to work on the equipment. Clear the work site of any unnecessary materials or materials that naturally build up electrostatic charge, such as foam packaging, foam cups, cellophane wrappers, and similar materials.

• Do not remove replacement or upgrade subassemblies from their antistatic packaging until the exact moment that you are ready to install them.

• Gather the tools, manuals, an ESD kit, and all other materials you will need before you remove covers and panels from the equipment. Procedures for removing subassemblies usually list required materials at the beginning. After you remove a cover or panel, you should avoid moving away from the work site; otherwise, you may build up an electrostatic charge.

• The SCSI connectors on the disk drive modules are particularly sensitive to ESD damage. Disk drive modules should be transported and stored in the ESD bags they are shipped in.

• Use an ESD kit when handling circuit boards or when touching the electronic circuits inside the equipment. If an emergency arises and an ESD kit is not available, follow the procedures in Emergency procedures (without an ESD kit) which follows. An ESD wrist band (part no. 129-002319) is supplied with your storage chassis.

• Replace the cover(s) or panel(s) on the equipment as soon as possible so that the electronic circuits are protected.

• If the equipment has an opening for an optional device (such as a mass-storage drive), and the device is not installed, make sure a filler panel is installed in the opening before connecting the equipment to the ac power outlet.

RAID Instructions

3-15


Emergency Procedures (without an ESD kit)

In an emergency when an ESD kit is not available, use the following procedures to reduce the possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential.

CAUTION: These procedures are not a substitute for the use of an ESD kit. Follow them only in the event of an emergency.

• Before touching any electronic circuits or boards inside the equipment, firmly touch a bare (unpainted) metal surface of the equipment.

• Before removing any replacement or upgrade subassembly from its antistatic bag, place one hand firmly on an unpainted metal surface of the chassis, and at the same time, pick up the replacement or upgrade subassembly while it is still sealed in the antistatic bag. Once you have done this, do not move around the room or contact other furnishings, personnel, or surfaces until you have installed and secured the subassembly in the equipment.

• Remove the subassembly from the antistatic bag, handling printed circuit boards by the edges. Avoid touching components and circuits on a printed circuit board.

• If you must move around the room or touch other surfaces before securing the subassembly in the equipment, first place the subassembly back in the antistatic bag. When you are ready again to install the subassembly repeat these procedures.

Precautions When Removing, Installing, or Storing CRUs

When removing or installing a CRU, never use excessive force. If you have difficulty removing or installing a CRU, read the procedures again. Once you have removed a

CRU, handle it gently because a sudden jar or drop could permanently damage it.

Your replacement or add-on CRU is sent to you in a specially designed shipping container. Store the CRU in this container, and use this container if you need to return the CRU for repair. The storage location of a disk module, SP, VSC module, or fan module must be maintained within the non-operating limits specified in Appendix A

Replacing or Adding a Disk Module

If you are replacing a failed module, start below with Removing a Disk Module. If you are adding an optional group, skip to Installing a DiskModule.

Removing a Disk Module

You can replace a failed disk module while the storage chassis is powered up. If necessary, you can also replace a disk module that has not failed, such as a module that has reported many “soft” errors. When replacing a module that has not failed, you must replace the module while the storage chassis is powered up so that the SP knows the module is being replaced.

RAID storage will support full Profile Video Disk Recorder operation with up to one disk failure per LUN (Logical Unit Number, a grouping of 5 disks). If more than one disk failure occurs in a single RAID unit (but in different LUNs), you must completely repair one of the failures before starting the repair of the next failure.

Repairing two failures at the same time will adversely affect RAID performance.

NOTE: Never remove a disk module until you are ready to install a replacement. If you must remove the failed module when a replacement is not available, install a disk filler module in the empty slot to maintain proper cooling (see “Removing or

Installing a Disk Filler Module”).

CAUTION: Disk modules are extremely sensitive to shock and vibration. Do not drop or set down hard. Do not store or transport unpackaged modules. A defective module must be returned to Tektronix in its original shipping container.

Before replacing a disk module, verify that the suspected module has actually failed.

If you remove the wrong disk module, you introduce an additional fault that shuts down the physical disk containing the failed module. In this situation, the operating system software cannot access the physical disk until you initialize it again.

To remove a disk module:

1. Read Avoiding Electrostatic Discharge (ESD) Damage.

2. Attach the clip of the ESD wrist band (strap) to the ESD bracket at the bottom of the storage chassis as shown below, and put the wrist band around your wrist with the metal button against your skin.

Removing or Installing a Disk Filler Module

When the storage chassis has an empty disk module slot, you must install a disk filler module to maintain the proper cooling air flow and to suppress the transmission of electromagnetic waves that could otherwise interfere with radio and communications equipment located nearby. (Refer to the Note and Warning in the front of this manual.) If you are adding a RAID group (five disk modules), you must remove the filler modules covering the empty slots.

CAUTION: If you are replacing a failed disk module and you do not have a disk filler module, leave the failed module installed until a replacement module is available.

To remove a disk filler module, grasp the module and pull it out of the chassis. If you cannot grasp the module, use a medium flat blade screwdriver to gently pry it out.
