Add a SCRATCH or UNKNOWN volume as MEMBER2 to the mirrored volume set PROD_SET for LDEVS 32 and 33 using a ":" between the set and volume name:
volutil: NEWMIRRVOL PROD_SET:MEMBER2 (32,33)
*Verify: Initialize new member volume on ldev 32 and ldev 33 [Y/N]? Y
*Note: New member volume has been initialized for ldev 32 and ldev 33.
volutil:EXIT
NOTE: After executing the NEWMIRRVOL command, you should execute a :VSCLOSEvolsetname and a :VSOPENvolsetname to ensure that
the volume set information has been posted to the disk.
Add remaining members to the mirrored volume set as needed.
