Note: If you are upgrading a server cluster and you try to use
MMC after upgrading
SnapDrive on the first node and before upgrading
SnapDrive on the remaining nodes, you get an error message indicating that the
SnapDrive service is unavailable owing to an invalid tag. This message is the result of the temporary presence of two versions of
SnapDrive on the same cluster. No corrective action is needed; just upgrade
SnapDrive on the other nodes.
