Checking storage subsystem status
Controllers in Device - Provides a logical grouping of RAID Controllers by device.
Controller - Represents the RAID Controllers found. These are numbered in the
order discovered. The controller icon represents both RAID Controller A and, if
installed, RAID Controller B. To determine if an optional RAID Controller B is
installed, select the Controller icon in the tree view, then examine the status pane
for peer status.
Bound LUNs - Expanding the Bound node displays all bound LUNs.
LUN - Represents a bound LUN. Expanding the LUN node displays the disk
modules that make up the LUN.
UnBound disks - Expanding the UnBound node, displays all unbound disk
modules.
Disks - Represents the disk modules.
The Storage Utility detects disks available and lists them on the opening screen.
The Storage Utility names the disks by the number of the slot in which they are
installed.
Refer to the following procedures to use Storage Utility for maintenance tasks
Checking storage subsystem status
Some limited status information for storage subsystems is displayed in the Storage
Utility. This can be helpful when configuring storage. You can view status
information by selecting items in the tree view.
Checking controller microcode
As explained in the previous section, to check controller microcode, select the
controller in the tree view and the microcode version is displayed.
Identifying disks
The Identify feature allows you to flash the disk LEDs so that you can physically
locate a specific disk module or group of disk modules that make up a LUN. Always
use the disk identify feature before removing and replacing a failed disk module.
Accidentally removing the wrong disk module can destroy all data on the disk drives.
