8. Determine the status of all storage subsystems and components in the
configuration by completing the following steps:
a. Check all LEDs on each component in the storage expansion enclosures.
Ensure that all the LEDs show normal status. For more information on LED
status for storage expansion enclosures, see “Checking the LEDs” on page
125 or the Installation, User’s, and Maintenance Guide for your DS4000
storage expansion enclosure.
b. Check all LEDs on each component in the storage subsystem. Ensure that
all the LEDs show normal status. For information about LED status, see
“Solving problems” on page 183.
c. Open the DS4000 Storage Manager Subsystem Management window, and
display the Physical View for the configuration.
The status for each component will be either Optimal or Needs Attention.
d. Review the status of the configuration components shown in the
Subsystem Management window by selecting the appropriate component
button for each storage subsystem.
9. Are the LEDs indicating normal operation, and is the status Optimal on all the
configuration components?
v Yes — End of procedure.
v No — Go to step 10.
10. Diagnose and correct the fault by completing the following steps.
a. Run the DS4000 Storage Manager Recovery Guru by selecting the
Recovery Guru toolbar button in the Subsystem Management window.
b. Complete the recovery procedure.
If the Recovery Guru directs you to replace a failed component, use the
individual LEDs on the storage subsystem to locate the specific failed
component. For troubleshooting procedures, see Chapter 6, “Hardware
maintenance,” on page 183.
c. When the recovery procedure is completed, select Recheck in the
Recovery Guru. This action reruns the Recovery Guru to ensure that the
problem has been corrected.
d. If the problem persists, contact your IBM service representative.
Installing the DS4000 Storage Manager client
Refer to the IBM System Storage DS4000 Storage Manager Installation and Host
Support Guide for the appropriate operating system for instructions on how to install
the Storage Manager software. Use that document and the online help to configure
the logical drives, partitions, and so on for the RAID controllers. Use your operating
system documentation to make the new logical drives accessible to the operating
system. Do not proceed with the configuration setup until you have completed the
DS4000 Storage Manager installation.
Assemble any additional items in preparation for software installation. These items
might include the following:
v HBA drivers
v Controller firmware version listed at the IBM DS4000 System Storage Support
Web site:
www.ibm.com/systems/support/storage/disk
v IP addresses for RAID controllers (for in-band management only)
v Additional documentation for switches and HBAs, if needed
