8.
One of the I/O modules may be failed even though the amber LED is not on. Replace the I/O
modules one by one as follows:
a.
Remove the left (top or bottom as identified in step 4) I/O module and replace it with a
new module as follows:
a.
Detach the SAS cable connecting the I/O module to the X9700c controller.
b.
Ensure that the disk drawer is fully pushed in and locked.
c.
Remove the I/O module.
d.
Replace with a new I/O module (it will not engage with the disk drawer unless the
drawer is fully pushed in)
e.
Re-attach the SAS cable. Ensure it is attached to the “IN” port (the bottom port).
b.
Re-seat the appropriate X9700c controller as described below in the section
“Re-seating
an X9700c controller” (page 105)
.
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 105)
.
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 105)
.
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.
