RAID Controller Submodel Not Supported

What Caused the Problem?

The submodel number associated with this RAID controller module was not set at the factory or it is not supported by the RAID controller module firmware. The Recovery Guru Details area provides specific information you will need as you follow the Recovery Steps.

Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.

Important Notes

The storage array currently does not have redundant RAID controller modules. The storage array will continue to operate with the remaining RAID controller module. However, failure of the remaining RAID controller module will result in a loss of access to the storage array. Therefore, make sure you correct this problem as soon as possible.
Note that there may be nothing wrong with the incompatible RAID controller module and that it may be compatible with another storage array. It can be used as a replacement for a RAID controller module that has the same replacement part number.
If using DHCP configuration on the RAID controller module, before you insert a new RAID controller module into the storage array if needed first update the DHCP server so that it will associate the new RAID controller module's hardware Ethernet (MAC) address with the IP address previously assigned to the removed RAID controller module.
The Service Action Allowed field in the Details area indicates whether you can safely remove the component. If the Service Action Allowed field is NO, then the affected component must remain in place until you service another component first.

Recovery Steps

If...	Then...
Your storage array has one controller	Go to "Procedure for Storage Arrays with One Controller."
Your storage array has two controllers	Ensure that multipath failover driver is installed and running on all attached hosts. Go to "Procedure for Storage Arrays with Two Controllers."

Procedure for Storage Arrays with One Controller

1	Stop all I/O to this storage array.
2	Turn off power to all the power supply/cooling fan modules in the tray containing the battery problems.
3	Check that the replacement RAID controller module has the same part number as the remaining RAID controller module. Contact your technical support representative to obtain a Dell-supported RAID controller module.
4	Remove the incompatible RAID controller module listed in the Details area.
5	Make sure at least 1 minute has elapsed. Then, insert the replacement RAID controller module firmly into place.
6	Check the RAID controller module status by clicking the Storage array profile link from the Summary tab. Then, click the RAID Controller Module tab and scroll down to the status of the replacement RAID controller module. The RAID controller module should have an Optimal status.
7	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 Controllers

1	Check that the replacement RAID controller module has the same part number as the remaining RAID controller module. Contact your technical support representative to obtain a Dell-supported RAID controller module.
2	Remove the incompatible RAID controller module (0 or 1) listed in the Details area.
3	Make sure at least 1 minute has elapsed. Then, insert the replacement RAID controller module firmly into place.
4	Check the RAID controller module status by clicking the Storage array profile link from the Summary tab. Then, click the RAID Controller Module tab and scroll down to the status of the replacement RAID controller module. The RAID controller module should have an Optimal status.
5	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.
