Attempting to Create a Mirrored VDisk Returns: "CMMVC6350E The command failed because there is insufficient mirror bitmap space"

Technote (troubleshooting)


The VDisk mirroring feature requires sufficient bitmap memory to be allocated in the I/O group before it can be used. Attempting to create mirrored VDiisks before allocating sufficient memory will result in the following error:

CMMVC6350E The command failed because there is insufficient mirror bitmap space
