General problems
Table 14. General symptoms and actions
v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v If an action step is preceded by “(Trained technician only)”, that step must be performed only by a trained
technician.
v Go to the IBM support website at http://www.ibm.com/supportportal to check for technical information, hints,
tips, and new device drivers or to submit a request for information.
Symptom Action
A cover latch is broken, an LED
is not working, or a similar
problem has occurred.
If the part is a CRU, replace it. If the part is a microprocessor or the system board,
the part must be replaced by a trained technician.
The server is hung while the
screen is on. Cannot start the
Setup utility by pressing F1.
1. See “Nx-boot failure” on page 164 for more information.
2. See “Recovering the server firmware (UEFI update failure)” on page 161 for
more information.
Hard disk drive problems
Table 15. Hard disk drive symptoms and actions
v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v If an action step is preceded by “(Trained technician only)”, that step must be performed only by a trained
technician.
v Go to the IBM support website at http://www.ibm.com/supportportal to check for technical information, hints,

Symptom Action
Not all drives are recognized by
the hard disk drive diagnostic
tests.
Remove the drive that is indicated by the diagnostic tests; then, run the hard disk
drive diagnostic tests again. 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.
Remove the hard disk drive that was being tested when the server stopped
responding, and run the diagnostic test again. If the hard disk drive diagnostic
test runs successfully, replace the drive that you removed with a new one.
A hard disk drive was not
detected while the operating
system was being started.
Reseat all hard disk drives and cables; then, run the hard disk drive diagnostic
tests again.
A hard disk drive passes the
diagnostic Fixed Disk Test, but
the problem remains.
Run the diagnostic SCSI Fixed Disk Test (see “Running DSA Preboot diagnostic
programs” on page 138).
Note: This test is not available on servers that have RAID arrays or servers that
have SATA hard disk drives.
A hard disk drive has failed,
and the associated yellow hard
disk drive status LED is lit.
(Hot-swap hard disk drives)
1. Re-configure the integrated SAS/SATA controller with RAID capabilities and
the devices that are attached to it.
2. Run the DSA disk drive test (see “IBM Dynamic System Analysis” on page
136).
3. If the drive fails the test, replace the drive.
