Resolving a pool conflict caused by inserting a foreign disk group
If you insert a virtual disk group, a disk that contains a virtual disk group, or a disk that was actively part of a virtual disk group from one system into another system, the latter system will attempt to create a virtual pool for that disk group.
If that system already has a virtual pool with the same name, the pool for the inserted disk group will be offline. For example, if NewSystem has pool A and you insert a disk group that came from OldSystem pool A, the disk group imported from OldSystem pool A will be offline.
NOTE You cannot access the two sets of pool A data (OldSystem and NewSystem) concurrently on a single storage system.
NOTE If you are unable to find a pool with a duplicate name, or are unsure of how to safely proceed, download logs from the system and contact technical support for assistance with offline disk groups.
