Removed EMM Module

What Caused the Problem?

An EMM module has either been removed from the expansion enclosure or is present but is being reported as removed because it is not seated properly. 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 equipment.

Important Notes

Correct this failure as soon as possible. Although the expansion enclosure is still operational, a level of redundancy has been lost. If the other EMM module or its communication path fails, all I/O to that expansion enclosure will fail.
Both EMM modules in the same expansion enclosure must have the same firmware version and be the same hardware type.

Recovery Steps

Use the location information in the Recovery Guru Details area to identify the affected expansion enclosure and the location of the affected EMM.

Check the expansion enclosure to determine if the affected EMM module has actually been removed or is present but may not be seated properly.

If...

Then...

The affected EMM module is present

Caution: Potential for data loss. Make sure you correctly identify the module listed as removed. Removing the remaining optimal module while I/O is in progress can cause data loss.

a	Remove and reseat the cables of the affected EMM and wait 40 seconds for the storage array to detect and register the EMM module.
b	Remove and reseat the affected EMM module and wait 40 seconds for the storage array to detect and register the EMM module.
c	Go to step 2.

The affected EMM module has been removed

If available, reinsert the removed EMM module. If the removed EMM module is not available, perform the following steps:

a	Obtain a Dell-supported EMM module.
b	Insert the replacement module.
c	Wait 40 seconds for the storage array to detect and register the EMM module.
d	Go to step 2.

Click Recheck 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.
