Removing and Inserting Enclosure Management Modules on Attached Expansion Enclosures

The following procedures describe how to safely remove and insert an enclosure management module (EMM) from an expansion enclosure attached to the MD3000/MD3000i.

NOTICE: Failure to follow these guidelines may result in a physical disk failing during removal and/or inadvertent removal of its redundant data path.

Removing an EMM from the Expansion Enclosure

1Check the Recovery Guru to confirm that there is no loss of physical disk path redundancy.

•If there is no loss of redundancy, check the channel. If it matches the EMM you are removing, you can safely remove it now.

•If redundancy is lost, run the following command. Note that channel [1] is the degraded channel.

“set physicalDiskChannel channel [1]

status = optimal;”

2Verify that the path to the channel is restored. The Recovery Guru may take several minutes to update.

Inserting an EMM into an Expansion Enclosure

1Make sure to always insert the EMM without SAS cables attached.

After the EMM is inserted, wait at least 30 seconds before attaching the SAS cables.
