2. Check the seven-segment display and note the following as it applies to your situation:
• If the seven-segment display shows “on,” then both X9700c controllers are operational.
• If the seven-segment displays shows “on” but there are path errors as described earlier in this
document, then the problem could be with the SAS cables connecting the X9700c controller
to the SAS Switch in the blade chassis. Replace the SAS cable and run the exds stdiag
command, which should report two controllers. If not, try connecting the SAS cable to a dif-
ferent port of the SAS switch.
• If the seven-segment displays does not show “on,” it shows an alphanumeric code. The number
represents the controller that has an issue. For example “C1” indicates the issue is with con-
troller 1 (the left controller). Press the down button beside the seven-segment display. This
display now shows a two-digit number. The following table describes the codes where n is
1 or 2 depending on the affected controller:

Cn 02
Re-seat the controller as described later in this
document If the fault does not clear, report to
HP Support to obtain a replacement controller.
Fault is in the X9700c controller. The fault
is not in the X9700cx or the SAS cables
connecting the controller to the I/O mod-
ules.

3. Check the SAS cables connecting the halted X9700c controller and the X9700cx I/O modules.
Disconnect and re-insert the SAS cables at both ends. In particular, ensure that the SAS cable is
fully inserted into the I/O module and that the bottom port on the X9700cx I/O module is being
used.
If there are obvious signs of damage to a cable, replace the SAS cable.
4. Re-seat the halted X9700c controller:
a. Push the controller fully into the chassis until it engages.
b. Reattach the SAS cable that connects the X9700c to the SAS switch in the c-Class blade
enclosure. This is plugged into port 1.
Wait for the controller to boot, then check the seven-segment display.
• If the seven-segment display shows “on,” then the fault has been corrected and the system
has returned to normal.
• If the seven-segment display continues to shows an Hn 67 or Cn 02 code, continue to the
next step.
5. At this stage, you have identified that the problem is with an X9700cx I/O module. Determine
if the fault lies with the top or bottom modules. For example, if the seven-segment display shows
C1 02, then the fault may lie with one of the primary (top) I/O modules.
6. Unmount all file systems using the X9000 management console. For more information, see the
HP StorageWorks X9000 File Serving Soft ware User Guide.
