8. If applicable, change the IP address of the Ethernet port in the management
station to a value that is on the same TCP/IP subnet as the controller Ethernet
port IP addresses that you just assigned. Exit DS4000 Storage Manager, then
restart.
9. Add a new storage subsystem entry in the Enterprise Management window,
using the new assigned IP addresses.
Note:
To manage storage subsystems through a firewall, configure the firewall to
open port 2463 to TCP data.
Monitoring status through software
Use the DS4000 Storage Manager client to monitor the status of the storage
subsystem. Run the software constantly, and check it frequently.
Notes:
1. You can only monitor storage subsystems that are within the management
domain of the storage-management software.
2. If you have not installed the DS4000 Storage Manager Event Monitor service as
part of the storage-management software installation, the DS4000 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: Refer to the IBM System Storage DS4000 Storage Manager 9.19
Installation and Support Guide for the appropriate operating system for
instructions on how to install the DS4000 Storage Manager 9.19 host
software.
In addition, to download the latest version of the DS4000 Storage
Manager host software, the DS4500 Storage Subsystem controller
firmware and NVSRAM, and the latest DS4000 ESM firmware, go to

The DS4000 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 Fault 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 Fault LED does not turn on. Only the
DS4000 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, 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
