IBM DS3500, Installation, User & Maintenance Manual

Guide for the operating system. Save the profile in a location other than the logical
drives that are created for the storage subsystem.
Always see the readme file that is included with the DS3500 Storage Subsystem
firmware package (whether the firmware is accessed by the Web or a CD) for any
special requirements or restrictions that apply to that firmware version.
Note: Be sure to install the DS Storage Manager event monitoring service to
enable continuous monitoring of the status of the storage subsystem. For
more information about the importance of this information, see “Monitoring
status through software.”
Monitoring status through software
Use the DS Storage Manager software to monitor the status of the storage
subsystem. Run the software constantly, and check it frequently.
Notes:
1. You can monitor only storage subsystems that are within the management
domain of the storage-management software.
2. If you have not installed the DS Storage Manager Event Monitor service as part
of the storage-management software installation, the DS Storage Manager
Enterprise Management window must remain open. (If you close the window,
you will not receive any alert notifications from the managed storage
subsystems.)
For more information, see the Enterprise Management online help.
Important: See the DS Storage Manager 10 Installation and Host Support Guide
for the applicable operating system for instructions for installing the DS
Storage Manager software. The document is in the Documentation
folder on the IBM
System Storage DS3500 Support DVD.
To download the latest version of the DS Storage Manager software,
controller firmware, NVSRAM firmware, and the latest ESM firmware,

The DS Storage Manager software provides the best way to diagnose and repair
storage-subsystem 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 hard disk drive exceeds its Predictive Failure
Analysis [PFA] threshold), the amber LED is not lit. Only the DS 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 DS Storage Manager
software can identify the risk level and provide the necessary recovery procedures.
