Hypervisor Problems - IBM System x3650 M3 4255 Service Manual

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 4, "Parts listing, Types 4255, 7945, and 7949 server," on page 157 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.
Symptom
A replacement hard disk drive
does not rebuild.
A green hard disk drive activity
LED does not accurately
represent the actual state of the
associated drive.
An amber hard disk drive status
LED does not accurately

IBM System x3650 M3 Types 4255, 7945, and 7949: Problem Determination and Service Guide
Action
1. Make sure that the hard disk drive is recognized by the controller (the green
hard disk drive activity LED is flashing).
2. Review the SAS RAID controller documentation to determine the correct
configuration parameters and settings.
1. 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 diagnostic programs" on page 72.
2. Use one of the following procedures:
v If there is a hard disk error log, replace the affect hard disk drive.
v If there is a no hard disk error log, replace the affect backplane.
1. If the amber hard disk drive LED and the RAID controller software do not
indicate the same status for the drive, complete the following steps:
a. Turn off the server.
b. Reseat the SAS controller.
c. Reseat the backplane signal cable, backplane power cable, and SAS
expander card (if the server has 12 drive bays).
d. Reseat the hard disk drive.
e. Turn on the server and observe the activity of the hard disk drive LEDs.
2. See "Problem determination tips" on page 155.
Action
1. Make sure that the optional hypervisor device is selected on the boot menu (in
the Setup utility and in F12).
2. Make sure that the hypervisor internal flash memory device is seated in the
connector correctly (see "Removing a USB hypervisor memory key" on page
186 and "Installing a USB hypervisor memory key" on page 187).
3. See the documentation that comes with your optional hypervisor device for
setup and configuration information.
4. Make sure that other software works on the server.
