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:

Re-seat the controller as described later in this docu-
ment 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 modules.
Other code
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.
