exds stdiag command, which should report two controllers. If not, try connecting the
SAS cable to a different 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 controller 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:
Code
Hn 67
Cn 02
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.
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 GUI. For more information, see the HP IBRIX X9000 Network
Storage System File System User Guide.

Explanation
Controller n is halted because there is a
connectivity problem with an X9700cx I/O
module

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.

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.
