A memory parity error was detected on a controller. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
If... | Then... |
Your storage subsystem has one controller | Go to "Procedure for Storage Subsystems with One Controller." |
Your storage subsystem has two controllers | If there are any hosts connected to this storage subsystem that are NOT running a host-based, multi-path failover driver, stop I/O to the storage subsystem from each of these hosts.
Go to "Procedure for Storage Subsystems with Two Controllers." |
1 | From the Controllers tab of the Storage Subsystem Profile, check the replacement part number of the affected controller and ensure that you have a new controller with the same replacement part number.
If you do not have a controller with the appropriate replacement part number, contact your technical support representative. |
||||||
2 | Stop all I/O to this storage subsystem. | ||||||
3 |
Turn off power to all power-fan canisters in the enclosure containing the failed controller. |
||||||
4 | Remove the affected controller.
|
||||||
5 | Important: If the new controller canister does NOT contain a battery, insert the battery from the old controller canister into the new replacement controller canister. Consult your hardware documentation for details.
Make sure at least 1 minute has elapsed. Then, insert the new (compatible) controller canister firmly into place. |
||||||
6 | Turn on power to all power-fan canisters in the enclosure.
Wait until all drives have completed the spin-up process, and then go to step 7. |
||||||
7 | From the Controllers tab of the Storage Subsystem Profile, check the status of the controller. The controller should have an optimal status. | ||||||
8 | Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative. |
1 | Place the affected controller offline.
