Displaying Pair Status Using Pprc Commands - HP StorageWorks XP24000 User Manual

Displaying Pair Status Using PPRC Commands

The CQUERY TSO and PPRCOPY QUERY ICKDSF commands are equivalent to the SIz pair status
display and status and history functions.
ShadowImage for Mainframe supports multiple T-VOLs for an S-VOL, and SIz and TCz can both
be defined for the same volume. When multiple pairs exist on one volume, the CQUERY and the
PPRCOPY QUERY commands can only report the status of one pair.
status displayed by the host for the SIz and/or TCz volume pair configurations.
If the HP disk array contains only ShadowImage for Mainframe pairs, the CQUERY and the
PPRCOPY QUERY commands will report the ShadowImage for Mainframe pair status.
If the HP disk array contains only TrueCopy for Mainframe pairs, the CQUERY and the
PPRCOPY QUERY commands will report the TCz pair status.
If the HP disk array contains both ShadowImage for Mainframe and TrueCopy for Mainframe
pairs, the CQUERY and the PPRCOPY QUERY commands will report the TCz pair status.
To obtain the SIz pair status, issue the status command to the SIz T-VOL or use the ShadowImage
for Mainframe remote console software to view the SIz pair status.
If an S-VOL has multiple T-VOLs, the status command will report pair status for the pair whose
T-VOL has the lowest LDEV ID. To obtain the status of a ShadowImage for Mainframe pair
with one of the other T-VOLs, issue the status command to the desired T-VOL. See
