Avoiding Problem Situations

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

Software Version 8.7A for Novell NetWare

Adding, Moving, and Changing Devices

The array controller maintains a configuration map of device types and locations. This

map is used to communicate with devices. If you add, move, or change a device while

the array controller is powered off without first changing the array controller

configuration, the array controller is not able to communicate with the changed device

when it returns to service.

If a device is removed by mistake while the array controller is off, delete all containers

associated with the removed device after power was restored to the array controller.

If a device is replaced while the array controller is off, install the replacement device

before restoring power to the array controller. Once power is restored, use the

DELETE DISK CLI command to remove the disk from the configuration. Then use the

ADD DISK CLI command to add the new device. This correctly removes the failed

device and adds the new device after restoring power to the array controller.

See the HSG80 Array Controller ACS Version 8.7 CLI Reference Guide for details on

CLI command usage and syntax.

See the HSG80 Array Controller ACS Version 8.7 Maintenance and Service Guide for

correct device removal and addition procedures.

Moving Storagesets

Move only normal storagesets. Do not move storagesets that are reconstructing or

were reduced.

CAUTION: Ensure all storagesets are in normal mode prior to moving them, or data

corruption occurs.

Replacing Array Controllers, Cache Modules, or External

Cache Battery Storage Building Blocks

You can replace the array controller, cache module, or external cache battery (ECB)

storage building block (SBB) while the storage system is shut down. However, you

must enter the

SHUTDOWN THIS_CONTROLLER command prior to shutting down the

storage system in order to make configuration changes. If two array controllers are

configured in a dual-redundant configuration, you must first enter the

SHUTDOWN OTHER_CONTROLLER command.
