7.1 Hot Swap Operating Instructions

To maintain array up time, individual disk drive sled assemblies, power supplies and blower assemblies can be replaced with the unit fully operational. Special instructions need to be followed to perform these operations.

Disk drives

The following cautions must be observed when hot swapping disk drives.

•Individual disk drive sled assemblies may be replaced while the array is operating with no other intervention only if there is absolutely no activity on that drive. Failure to ensure no activity may destroy any data on that drive and possibly stop the entire array operation. Follow the instructions below using CLI commands to replace drives.

•Removing a drive sled that is part of a RAID Level 0 group will result in the loss of all data in the groups associated with that sled. Follow your backup procedures when removing sleds.

•Do not leave empty openings on the front or rear of the array under any circumstances. Empty openings affect airflow and may cause the unit to overheat and shut down.

•All modular components must be replaced by qualified personnel only. Components are electrostatic sensitive. Use a static wriststrap when handling any of the cards inside the array. Use proper grounding methods. Always store spare components in proper ESD containers when not in use.

Follow your backup procedures before removing a sled. You may copy drives using the appropriate CLI commands (Refer to Drive Configuration Commands on page 45).

The following method is the safest way to perform a hot swap of a drive.

The general approach: identify the disk drive sled to be replaced, take it offline using the appropriate CLI commands, turn off its power using CLI commands, remove and replace with a new disk drive sled, power up the new sled, and place back on line.

1Connect to Diamond Storage Array services (refer to Accessing the Array on page 17) and enter the Command Line Interface mode.

2The fault LED should be blinking on the disk drive sled to be replaced. If it is not, type set SledFaultLED [n] on. The LED of the drive you want [n] will light.

3Determine the Drive Sled Number. The disk drive sled closest to the management card is always the number 1 disk drive sled

The Drive Sled Number identified in step 2 is the SledNum variable to be entered into the CLI commands. Take the disk drive sled offline by entering the following CLI commands at the control computer Ready prompt

Set AtaDiskState (SledNum, 1, OFFLINE)

Set AtaDiskState (SledNum, 2, OFFLINE)

Set DriveSledPower (SledNum, OFF)

CAUTION

In a Hot Spare configuration, a drive sled should only be taken offline if there is absolutely no activity on that drive. If there is any activity, the rebuild of the Hot Spare sled may be flawed.

4Wait 30 seconds for the disk drive sled to spin down and complete any remaining I/O activity.

5Unscrew the two screws on the disk drive sled with the appropriate tool.

6Carefully pull the disk drive sled out of chassis using its handle.

7Mark or tag the disk drive sled with the array serial number, the date removed, and its slot number.

8Place the disk drive sled in an appropriate ESD container or bag.

9Install the replacement disk drive sled into the array chassis using proper ESD control steps and with the proper orientation (The disk drive sled assembly is keyed and can only be inserted one way).

10Tighten the two screws on the disk drive sled with the appropriate tool.

11If you do not have AutoRebuild enabled, using the disk drive sled number identified in step 2, on the control computer Ready prompt type
