• If the storage system contains both Siz and TCz pairs, the CQUERY and PPRCOPY QUERY
commands reports the TCz pair status.
NOTE:
To obtain the Siz pair status, issue the status command to the Siz T-VOL or use the Siz Remote Web
Console software to view the Siz pair status.
• If an S-VOL has multiple T-VOLs, the status command reports pair status for the pair whose
T-VOL has the lowest LDEV ID. To obtain the status of a Siz pair with one of the other T VOLs,
issue the status command to the desired T-VOL.
