HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)

14. Resume I/O on the filesystems that were paused in step 1 by running the following command on
each filesystem that was suspended, from the same server on which the suspend command was
run:
# psfsresume filesystem-path
where filesystem-path is the full path to the filesystem mount point on the server.
NOTE:
The filesystem resume command must be run on a server that has the filesystem
mounted. Make sure to execute the filesystem resume command on the same server on which
the corresponding filesystem suspend was run. If a filesystem fails to resume, re-issue the
filesystem resume command .
Re-Seating an X9700c controller
Make sure you are re-seating the correct controller. You should observe both a flashing amber LED
and the seven-segment display. An H1 or C1 code indicates controller 1 (left) is halted; an H2 or C2
code indicates that controller 2 (right) should be re-seated.
NOTE:
There is no need to disconnect the SAS cables during this procedure.
To re-seat the controller:
1. Squeeze the controller thumb latch and rotate the latch handle down
2. Pull the controller out until it has clearly disengaged—there is no need to fully remove the controller.
3. While the controller is still disengaged, ensure that the SAS cables are fully inserted.
4. Push the controller fully into the chassis so it engages.
The seven-segment display shows different codes as the controller boots. After a few minutes, the
seven-segment display should show a constant value (if you had previously run a firmware flash utility,
this can take up to 25 minutes). If the value is “on,” the controller is operating normally. Otherwise,
see Table 8 for more information.
Troubleshooting specific issues
Apparent failure of P700m
Sometimes when a server is booted, the HP P700m cannot access the SAS fabric. This is more common
when a new blade has just been inserted into the blade chassis, but can occur on other occasions.
Symptoms include:
• The HP P700m reports a POST error—this is visible using the TFT monitor/keyboard.
• The server crashes when the cciss driver loads— this is visible using the TFT monitor/keyboard.
The exdsmgr syscheck command reports a pair of messages such as the following. This indicates
that server 3 cannot see either controller of array 3. Assuming other servers can see both controllers,
this may indicate something wrong with server 3
