This information provides steps for solving hard disk drive problems.
Table 29. Symptoms and actions for hard disk drive problems
v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See Chapter 5, “Parts listing, System x3750 M4 Types 8722 and 8733,” on page 215 to determine which

Symptom Action
Not all drives are recognized by
the DSA hard disk drive
diagnostic test.
1. Set up the RAID configuration before you run the DSA diagnostic tests.
2. Remove the drive that is indicated by DSA (see “Removing 2.5-inch and
1.8-inch hot-swap drives” on page 236); then, run the hard disk drive
diagnostic test again (see “Running the DSA Preboot diagnostic programs” on
page 187).
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 you run the DSA diagnostic tests.
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
236), and run the diagnostic test again (see “Running the DSA Preboot
diagnostic programs” on page 187).
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 238).
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.
