Apparent failure of HP 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.
Sometimes this happens to all servers in the system.
On X920 systems, no controllers are seen when you run the exds_stdiag command.
The underlying causes of these problems differ. However, the recovery process is similar in all
cases. Do not replace the HP P700m until you have worked through the process described here.
In general terms, the solution is to reset the SAS switches and if that fails, reboot each X9700c
controller until you locate a controller that is interfering with the SAS fabric.
If your system is in production, follow the steps below to minimize downtime on the system:
1. Log in to the Onboard Administrator and run the show bay info all command. Compare
entries for the affected blade and working blades.
If the entries look different, reboot each Onboard Administrator, one at a time.
Re-seat or replace the P700m in the affected server blade.
2. Run exds_stdiag. If exds_stdiag detects the same capacity blocks and X9720c controllers
as the other server blades, then the procedure is completed; otherwise, continue to the next
step.
3. If all servers are affected, shut down all servers; if a subset of servers is affected, shut down
the subset.
4. Using OA, log into the SAS switch 1 and reset it.
5. Wait for it to reboot.
6. Reset SAS switch 2.
7. Wait for it to reboot.
8. Boot one affected server.
9. Run the following command:
# exds_stdiag
10. If X9700c controllers can be seen, boot other affected servers and run exds_stdiag on
each. If they also see the X9700c controllers, the procedure is completed; otherwise continue
to the next step.
1 1. Perform the following steps For each X9700c controller in turn:
a. Slide out controller until LEDs extinguish.
b. Reinsert controller.
c. Wait for the seven-segment to show "on".
d. Run the exds_stdiag command on affected server.
e. If ok, the procedure is completed; otherwise, repeat steps a through d on next the
controller.
12. If the above steps do not produce results, replace the HP P700m.
13. Boot server and run exds_stdiag,
14. If you still cannot see the X9700c controllers, repeat the procedure starting with step 1.
If the system is not in production, you can use the following shorter procedure:
1. Power off all server blades.
2. Using OA, power off both SAS switches.
