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 x3850 X6 and x3950 X6 Types 3837 and 3839," on page 205 to determine
which components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).

service technician.
Symptom
The server fails to recognize
one drive.
Not all drives are recognized by
the DSA hard disk drive
diagnostic test.
The server stops responding
during the hard disk drive
diagnostic test.
Action
1. Verify that the drive is supported for this server. Check the IBM ServerProven
web site at http://www.ibm.com/systems/info/x86servers/serverproven/
compat/us/ for a list of supported hard drives.
2. Make sure that the drive is seated in the drive bay properly and that there is
no physical damage to the drive connectors.
3. Run the DSA SAS Fixed Disk or SAS Attached Disk diagnostic tests (see
"Running the DSA Preboot diagnostic programs" on page 175), then do the
following:
a. If the drive fails the diagnostic test, replace the drive.
b. If the drive passes the diagnostic tests but is still not recognized, complete
the following steps:
1) Replace the drive.
2) Replace the hard drive backplane.
3) Replace the standard I/O book ("Removing the standard I/O book" on
page 221 and "Replacing the standard I/O book" on page 222).
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 231); then, run the hard disk drive
diagnostic test again (see "Running the DSA Preboot diagnostic programs" on
page 175).
3. If the remaining drives are recognized, replace the drive that you removed
with a new one.
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
231), and run the diagnostic test again (see "Running the DSA Preboot
diagnostic programs" on page 175).
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 232).
