Virtual LVI volume
Note*1: You cannot use the volume as a data volume of the URz pair for delta resync operation.
Note*2: The volume can be used as a secondary data volume only when you restore a URz pair
or perform a Business Continuity Manager YKRESYNC REVERSE operation. However, even in this
case, you cannot use the volume as the secondary data volume of the URz pair for delta resync
operation.
Note*3: This is "No" if more than one primary storage systems and more than one secondary
storage system are used for remote copy (see
“Using More Than One Primary and Secondary
Storage System for Remote Console” (page 54)
).
Combining URz with XP Cache LUN Software
You can perform XP Cache LUN operations on primary and secondary data volumes in URz pairs.
If you need to perform Virtual LVI operations on a URz primary data volume or secondary data
volume, you must delete the pair first to return the volume to Simplex status.
When creating a URz pair consisting of two Virtual LVI volumes, make sure that the primary data
volume and the secondary data volumes have the same capacity.
Combining URz with Cache Residency Manager
You can perform Cache Residency Manager operations on URz primary data volumes and
secondary data volumes.
Combining URz and ShadowImage for z/OS
URz and ShadowImage for z/OS can be used together in the same storage system and on the
same volumes to provide multiple copies of data at the primary and/or secondary sites.
describes the host pair status reporting for URz volumes, SIz volumes, and
URz/SIz shared volumes.
shows the currency of the data on a shared URz/SIz
volume based on URz and SIz pair status.
•
For shared URz/SIz volumes, the URz pair status is reported to the host if you query the URz
primary data volume or secondary data volume. To obtain the SIz pair status, query the target
volume (T-VOL) of the SIz pair.
•
SIz supports multiple T-VOLs for each source volume (S-VOL). If you issue a pair status query
to a SIz S-VOL (for example, pairdisplay), the status for only one SIz pair is reported (the pair
with the T-VOL with the lowest LDEV ID). To obtain the pair status for the SIz pair(s) with the
other T-VOL(s), you must direct the host query to the specific S-VOL using the T-VOL’s LDEV ID
in the host command. The SIz remote console software displays the port, TID, LUN, LDEV ID
and SIz pair status of all T-VOLs associated with a S-VOL.
