problem has occurred.
Action
1. Review the storage subsystem logs for indications of problems within the
storage subsystem, such as backplane or cable problems.
2. See "Problem determination tips" on page 90.
1. Make sure that the hard disk drive is recognized by the adapter (the green hard
disk drive activity LED is flashing).
2. Review the SAS/SATA adapter documentation to determine the correct
configuration parameters and settings.
If the green hard disk drive activity LED does not flash when the drive is in use, run
the DSA Preboot diagnostic programs to collect error logs (see "Running the DSA
Preboot diagnostic programs" on page 68).
• If there is a hard disk drive error log, replace the affected hard disk drive.
• If there is no disk drive error log error log, replace the affected backplane.
1. If the yellow hard disk drive LED and the RAID adapter software do not indicate
the same status for the drive, complete the following steps:
a. Turn off the server.
b. Reseat the SAS/SATA adapter.
c. Reseat the backplane signal cable and backplane power cable.
d. Reseat the hard disk drive.
e. Turn on the server and observe the activity of the hard disk drive LEDs.

Action
1. Make sure that the optional embedded hypervisor device is selected on the

device for setup and configuration information.
