Deleting journal volumes from a journal
You can delete journal volumes as needed.
Prerequisite information
A journal volume can be deleted only when one or more of the following conditions exist:
If the pair belonging to the mirror in the journal is suspended and a reserve journal volume exists.
If the pair belonging to the mirror in the journal is deleted.
Deleting a journal volume from a journal in which a pair is registered causes the journal volume's LDEVs to become blockaded. You can release the blockade by formatting the LDEVs. For instructions on formatting volumes, see the Provisioning Guide for Virtual Storage Platform Gx00 and Fx00 Models.
To delete a journal volume, mirror statuses in the journal must be Initial, Stopped, or Hold(Failure), and a reserve volume exists.
The following table specifies the mirror status required for deleting journal volumes in the 3DC multi-target configuration.
