6.0 HP X9720 Network Storage System Administrator Guide (AW549-96034, December 2011)

c. Wait for the controller to boot.
• If the seven-segment display shows “on,” then the fault has been corrected and the
system has returned to normal and you can proceed to step 11.
• If the seven-segment continues to shows an Hn 67 or Cn 02 code, continue to the
next step.
d. If the fault does not clear, remove the left I/O module and reinsert the original I/O module.
e. Re-seat the appropriate X9700c controller as described below in the section “Re-seating
an X9700c controller” (page 120).
f. Wait for the controller to boot.
• If the seven-segment display shows “on,” then the fault has been corrected, the system
has returned to normal, and you can proceed to step 11.
• If the seven-segment display continues to shows an Hn 67 or Cn 02 code, continue
to the next step.
g. If the fault does not clear, remove the right I/O module and replace with the new I/O
module.
h. Re-seat the appropriate X9700c controller as described below in the section “Re-seating
an X9700c controller” (page 120).
9. If the seven-segment display now shows “on,” run the exds_stdiag command and validate
that both controllers are seen by exds_stdiag.
10. If the fault has not cleared at this stage, there could be a double fault (that is, failure of two
I/O modules). Alternatively, one of the SAS cables could be faulty. Contact HP Support to
help identify the fault or faults. Run the exds_escalate command to generate an escalate
report for use by HP Support as follows:
# exds_escalate
11. At this stage, an X9700cx I/O module has been replaced. Change the firmware of the I/O
modules to the version included in the X9720 Network Storage System:
a. Identify the serial number of the array using the command:
exds_stdiag
b. Run the X9700cx I/O module firmware update command:
# /opt/hp/mxso/firmware/exds9100cx_scexe –s
The command will pause to gather the system configuration, which can take several
minutes on a large system. It then displays the serial number of an array and asks if it
should be updated. If the serial number displayed is not the array to be updated, select
N for “no.”
The command will continue to display serial numbers. When it reaches the desired array,
select Y to update the firmware.
NOTE: If you reply Y to the wrong array, let the command finish normally. This can do
no harm since I/O has been suspended as described above (and the I/O modules should
already be at the level included in the X9720 Network Storage System).
c. After the array has been flashed, you can exit the update utility by entering q to quit.
d. Press the power buttons to power off the affected X9700c and X9700cx.
e. Re-apply power to the capacity block. Power on the X9700cx first, then the associated
X9700c. The firmware update occurs during reboot, so the reboot could take longer than
usual (up to 25 minutes). Wait until the seven-segment display of all X9700c enclosures
goes to the “on” state before proceeding. If the seven-segment display of an X9700c has
not returned to "on" after 25 minutes, power cycle the complete capacity block again.
