URz volumes can be assigned to SIz pairs, and vice versa.
A primary volume (P-VOL) of Universal Replicator for Mainframe means a primary data volume of
Universal Replicator for Mainframe. A secondary volume (S-VOL) of Universal Replicator for
Mainframe means a secondary data volume of Universal Replicator for Mainframe.
ShadowImage for Mainframe and Universal Replicator for Mainframe can function together in the
same storage system to provide both internal and remote backup for your important data. To query
the status of a SIz pair when SIz and URz pairs share the same volume, do the following:
•
Query the SIz S-VOL and T-VOL status from the host if the SIz S-VOL and URz P-VOL share the
same volume,
•
Query the SIz T-VOL status from the host if the SIz S-VOL and URz S-VOL share the same
volume.
•
Query the SIz S-VOL status from the host if the SIz T-VOL and URz P-VOL share the same
volume.
ShadowImage for Mainframe supports multiple T-VOLs for each S-VOL. If you issue a pair status
query to an SIz S-VOL, the status for only one SIz pair is reported (the pair with the T-VOL and
with the lowest LDEV ID). To obtain the pair status for the SIz pairs with the other T-VOLs, you must
direct the host query to the specific T-VOL using the T-VOL’s LDEV ID in the host command. The SIz
remote console software displays the LDEV ID and SIz pair status of all T-VOLs associated with an
S-VOL.
When you perform PPRC command to the SIz/URz shared volumes to query the pair status, the
storage system reports pair status of the SIz. To query pair status of the URz from the host, use XP
for Business Continuity Manager Software™. For details regarding how to use XP for Business
Continuity Manager Software™, see the HP StorageWorks XP for Business Continuity Manager
Software User's Guide.
Table 9 (page 34) lists the currency of the data on shared SIz/URz volumes based on the SIz and
URz pair status.
