Not all drives are recognized by
the DSA hard disk drive
diagnostic test.
1. Set up the RAID configuration before running the DSA diagnostics.
2. Remove the drive that is indicated by DSA (see “Removing 2.5-inch and
1.8-inch hot-swap drives” on page 215); then, run the hard disk drive
diagnostic test again (see “Running the DSA Preboot diagnostic programs” on
page 171).
3. If the remaining drives are recognized, replace the drive that you removed
with a new one.
The server stops responding
during the hard disk drive
diagnostic test.
1. Set up the RAID configuration before running the DSA diagnostics.
2. Remove the hard disk drive that was being tested when the server stopped
responding (see “Removing 2.5-inch and 1.8-inch hot-swap drives” on page
215), and run the diagnostic test again (see “Running the DSA Preboot
diagnostic programs” on page 171).
3. If the hard disk drive diagnostic test runs successfully, replace the drive that
you removed with a new one (see “Replacing 2.5-inch and 1.8-inch hot-swap
drives” on page 216).
A hard disk drive has failed,
and the associated amber hard
disk drive status LED is lit. Check the IMM event log for hard disk drive events and resolve the problem.
