Ensure that you read the readme file that is included with the DCS3860 storage
system firmware package (whether the firmware is accessed by the Web or a DVD)
for any special requirements or restrictions that apply to that firmware version.
Note: Ensure that you install the Storage Manager event monitoring service to
enable continuous monitoring of the status of the storage system. For more
information about the importance of this information, see “Monitoring status
through software.”
Monitoring status through software
Run the software constantly, and check it frequently.
Note: You can monitor only storage systems that are within the management
domain of the Storage Manager. If you have not installed the Storage Manager
Event Monitor service as part of the storage-management software installation, the
Storage Manager Enterprise Management window must remain open. (If you close
the window, you will not receive any alert notifications from the managed storage
systems.)
For more information, see the Enterprise Management online help.
Important: For instructions to install the DS Storage Manager software, see the
IBM System Storage DS Storage Manager Version 10.8 Installation and Host Support
Guide
for the applicable operating system. The document is in the Documentation
folder on the IBM Support Software DVD.
To download the latest version of the Storage Manager software, controller
firmware, NVSRAM firmware, and the latest ESM firmware, go to

The Storage Manager software provides the best way to diagnose and repair
storage-system failures. The software can help you:
v Determine the nature of the failure
v
Locate the failed component
v
Determine the recovery procedures to repair the failure
Amber (needs attention) LEDs do not necessarily indicate which component has
failed or must be replaced or which type of recovery procedure you must perform.
In some cases (such as when a drive exceeds its Predictive Failure Analysis [PFA]
threshold), the amber LED is not lit. Only the Storage Manager software can detect
the failure.
For example, the recovery procedure for a PFA flag (impending drive failure) on a
drive varies depending on the drive status (hot spare, unassigned, RAID level,
current logical drive status, and so on). 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 Storage Manager
software can identify the risk level and provide the necessary recovery procedures.
Note: For PFA flags, the system-error LED and drive status LEDs are not lit, so
checking the LEDs will not notify you of the failure, even if the risk of data loss is
high.
