Preface

This manual describes how to maintain the hardware for PS6010 storage arrays. Each array contains hot-swappable power supply and cooling modules, eight or sixteen RAID-protected disks, and single or dual hot-swappable control modules.

With one or more PS Series arrays, you can create a PS Series group—a selfmanaging, iSCSI storage area network (SAN) that is affordable and easy to use, regardless of scale.

Audience

This manual is designed for the administrators responsible for maintaining PS6010 hardware. Administrators are not required to have extensive network or storage system experience. However, it may be useful to understand:

• Basic networking concepts

• Current network environment

• User disk storage requirements

• RAID configurations

• Disk storage management

Note: Although this manual provides examples of using PS Series arrays in

some common network configurations, detailed information about setting

up a network is beyond its scope.

Organization

This manual is organized as follows:

• Chapter 1, Basic Storage Array Information, describes the array front and back panels, how to interpret LEDs, how to use an electrostatic wrist strap, and how to shut down and restart an array.

• Chapter 2, Maintaining Disk Drives, describes how to install and remove disks.

• Chapter 3, Maintaining Control Modules, describes how to install and maintain control modules. It also describes the best way to connect network cables to control modules for high performance and availability.

1 Basic Storage Array Information

This chapter includes basic information about PS6010 storage arrays.

Array Front and Back Panels

The front of a PS6010 array is shown in Figure 1-1 and Figure 1-2.

Figure 1-1: PS6010 Front Panel (with Bezel)

Figure 1-2: PS6010 Front Panel (without Bezel)

The disk drives are accessible from the front, after you remove the bezel. See Chapter 2 for detailed information about disk drives.

The components on the back of a PS6010 are shown in Figure 1-3 and described in Table 1-1.

Interpreting Operations Panel LEDs

The operations panel monitors array hardware components. The panel is not redundant, but an array can continue to operate if it fails. See your array support provider for information about servicing the operations panel.

Figure 1-4 shows the operations panel LEDs, which can alert you to errors and conditions that require your attention. Table 1-2 describes the LEDs. Report any serious problems to your array support provider.

Warning LED Status Conditions

When the Warning LED is flashing orange, one or more of the following has occurred:

• RAID set is degraded but still functioning.

• RAID set (volume level) has lost blocks.

• Component temperature is near a limit.

• Fan failed or fan RPMs exceed limit.

• Power supply is not installed or has no power.

• Cache battery has less than 72 hours of charge.

• Only one control module installed or control module has failed over.

• Syncing active and secondary control modules.

• No communication between control modules.

• Installed spare disk drive does not have enough capacity to replace a disk drive in a RAID set.

• A non-critical hardware component failed.

• Real-time clock battery is low.

Critical LED Status Conditions

When the Critical LED is flashing orange, one or more of the following has occurred:

• RAID is not functioning.

• Lost block table is full.

1–4

PS6010 Hardware Maintenance Basic Array Information

• Temperature exceeds upper or lower limit.

• Control module cache has lost data.

• A cooling module is not installed.

• Both fans on a cooling module have failed.

• Cache battery temperature is too high to charge battery.

• NVRAM coin cell battery failed.

• Cache contains data that does not belong to any of the installed disk drives.

• More than one valid RAID set exists in array.

• Control modules are different models.

• A critical hardware component has failed.

• Operations panel failed or not installed.

• Storage enclosure processor that monitors array components has experienced a failure.

Using an Electrostatic Wrist Strap

When handling the array chassis, disk drives, or control modules, you must use an electrostatic protection device to prevent electrostatic discharge.

An electrostatic wrist strap is included in the shipping box.

To use the wrist strap:

1. Connect the steel snap on the coil cord to the stud on the elastic band. See

Figure 1-5.

1–5

PS6010 Hardware Maintenance Basic Array Information

Figure 1-5: Using an Electrostatic Wrist Strap

2. Fit the band closely around your wrist.

3. Connect the banan plug to ground, or attach the plug to the alligator clip and

connect the clip to a grounded device such as an ESD mat or the metal frame of a grounded piece of equipment.

Shutting Down and Restarting an Array

A PS6010 array includes redundant, hot-swappable disk drives, power supplies, and control modules (in a dual control module array). You can remove a redundant component without affecting operation if a functioning component is available. Otherwise, it is recommended that you cleanly shut down the array and turn off power before removing a component.

Note: When an array is shut down, any volumes with data on the array will be

set offline until the array is successfully restarted. This may affect initiators that are connected to the volumes.

1. Do one of the following:

• Use telnet or SSH to connect to a functioning IP address assigned to a

network interface on the array. Do not connect to the group IP address.

• Use the null modem cable shipped with the array to connect to Serial

Port 0 on the active control module (ACT LED is green) to a console or a computer running a terminal emulator.

Make sure the serial line characteristics are as follows:

- 9600 baud

-One STOP bit

1–6

PS6010 Hardware Maintenance Basic Array Information

- No parity

- 8 data bits

- No flow control

2. Log in to an account with read-write access, such as the

3. Enter the

Welcome to Group Manager

group1> shutdown

shutdown command, as shown next.

grpadmin account.

If you are using a serial connection to shut down an array, it is safe to turn off power when the “press any key” message appears. (Pressing any key will restart both control modules.)

If you are using a network connection, the session will be disconnected before the array is fully shut down. Confirm that the CACT LED on each control module is off (not lit) before turning off power to the array.

After performing array maintenance, you can turn on power to the array. When the array restart completes, the member and volumes will be set online.
