partitioning definitions, hardware changes, and so on), save the storage subsystem
profile as explained in the DS3000 Storage Manager guide for the operating
system. Save the profile in a location other than the logical drives that are created
for the DS3300.
Always see the readme file that is included with the DS3300 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 DS3000 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 DS3000 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 DS3000 Storage Manager Event Monitor service as
part of the storage-management software installation, the DS3000 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 IBM System Storage DS3000 Storage Manager Version 2
Installation and Support Guide for instructions for installing the DS3000
Storage Manager software. The Installation and Support Guide is in the
Documentation folder on the IBM System Storage DS3000 Support CD.
To download the latest version of the DS3000 Storage Manager
software, the DS3300 storage subsystem controller firmware and
NVSRAM, and the latest DS3000 ESM firmware, go to

The DS3000 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 DS3000 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
