9. See "Problem determination tips" on page 209.
Make sure that the hard disk drive, SAS/SATA adapter, and server device drivers
and firmware are at the latest level.
Important: Some cluster solutions require specific code levels or coordinated code
updates. If the device is part of a cluster solution, verify that the latest level of code
is supported for the cluster solution before you update the code.
1. Review the storage subsystem logs for indications of problems within the
storage subsystem, such as backplane or cable problems.

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 187).
• 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.
