Finding Controller, Storage Expansion Enclosure, And Drive Information - IBM DS5100 Installation, User's, And Maintenance Manual

Note: The version of controller firmware determines which version of the DS
The DS Storage Manager client provides the best way to diagnose and repair
storage-server failures. The software can help you do the following:
v Determine the nature of the failure
v Locate the failed component
v Determine the recovery procedures to repair the failure
Although the storage subsystem has Needs Attention LEDs, these LEDs do not
necessarily indicate which component has failed or needs to be replaced, or which
type of recovery procedure you must perform. In some cases (such as in the case
of a hard disk drive exceeding its PFAs), the Needs Attention LED does not turn on.
Only the DS Storage Manager client can detect the failure.
For example, the recovery procedure for a Predictive Failure Analysis (PFA) flag
(impending drive failure) on a drive varies depending on the drive status (hot spare,
unassigned, RAID level, or current logical drive status). Depending on the
circumstances, a PFA flag on a drive can indicate a high risk of data loss (if the
drive is in a RAID 0 volume) or a minimal risk (if the drive is unassigned). Only the
DS Storage Manager client can identify the risk level and provide the necessary
recovery procedures.
Note: For PFA flags, the General-system-error and Drive Needs Attention LEDs do
Recovering from a storage-server failure might require you to perform procedures
other than replacing the component (such as backing up the logical drive). The DS
Storage Manager client gives these procedures.

Finding controller, storage expansion enclosure, and drive information

You can view a Storage Subsystem Profile to find controller, enclosure, and drive
information for the storage subsystem and attached storage expansion enclosures.
To view a Storage System Profile, perform the following steps:
1. Open the Storage Subsystem Management window from the DS Storage
2. Select Storage Subsystem → View → Profile.
3. Select the Controllers tab.
4. Scroll through the list to find Board ID, Submodel ID, Product ID, and Product
5. Select the Enclosures tab.
6. Scroll through the list to find the Product ID for supported storage expansion
7. Select the Drives tab.
8. Scroll through the list to find the drive values such as Product ID.

risk of data loss is high.
Not following the software-recovery procedures can result in data loss.
