RAID Controller Module Memory Consistency Error

What Caused the Problem?

A memory consistency error was detected on a RAID controller module. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Important Notes

Recovery Steps

If... Then...
Your storage array has one RAID controller module Go to "Procedure for Storage Arrays with One RAID Controller Module."
Your storage array has two RAID controller modules If there are any hosts connected to this storage array that are NOT running a host-based, multi-path failover driver, stop I/O to the storage array from each of these hosts.

Go to "Procedure for Storage Arrays with Two RAID Controller Modules."

Procedure for Storage Arrays with One RAID Controller Module

1 From the RAID Controller Modules tab of the Storage Array Profile, check the replacement part number of the affected RAID controller module and ensure that you have a new RAID controller module with the same replacement part number.

If you do not have a RAID controller module with the appropriate replacement part number, contact your technical support representative.
2 Stop all I/O to this storage array.

3

Turn off power to all power-fan modules in the enclosure containing the failed RAID controller module.
4 Remove the affected RAID controller module.
If... Then...
You are using In-Band management for ALL hosts attached to this storage array Go to step 5.
You are using Out-of-Band management for ANY host attached to this storage array Before you insert a new RAID controller module module into the storage array, you must update the DHCP/BOOTP server for each Out-of-Band managed host so that it will associate the new RAID controller module's hardware Ethernet (MAC) address with the DNS/network name and IP address previously assigned to the removed RAID controller module.

To update the DHCP/BOOTP server, find the entry associated with the removed RAID controller module and replace its Ethernet (MAC) address with the new RAID controller module's Ethernet (MAC) address. The RAID controller module's Ethernet (MAC) address is located on an Ethernet ID label on the RAID controller module module in the form xx.xx.xx.xx.xx.xx.

When you are finished, go to step 5.
5 Important: If the new RAID controller module module does NOT contain a battery, insert the battery from the old RAID controller module module into the new replacement RAID controller module module. Consult your hardware documentation for details.

Make sure at least 1 minute has elapsed. Then, insert the new (compatible) RAID controller module module firmly into place.
6 Turn on power to all power-fan modules in the enclosure.

Wait until all physical disks have completed the spin-up process, and then go to step 7.
7 From the RAID Controller Modules tab of the Storage Array Profile, check the status of the RAID controller module. The RAID controller module 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.

Procedure for Storage Arrays with Two RAID Controller Modules

1 Place the affected RAID controller module offline.
a Select the RAID controller module in the physical view of the Array Management Window.
b Select Advanced >> Recovery >> Place RAID Controller Module >> Offline.
c Complete the instructions in the dialog, then select Yes.
2 Read all of the following steps before taking any action.
a Click the Recheck button to rerun the Recovery Guru.
b Select the Offline RAID Controller Module problem that is being reported in the Summary area.
c Complete the Recovery Steps in the Offline RAID Controller Module to replace the RAID controller module.
