Virtual LVI volume

Yes. Yes. Yes.

Note*1 — You cannot use the volume as a data volume of the URz pair for delta resync operation.

Note*2The vol

ume 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 on page 72).

Combining URz with Virtual LVI

You can perform Virtual LVI 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 ﬁrsttoreturn thevolumetoSimplex 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 per

form 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. Table 22 on page 82

describes the host pair status reporting for URz volumes, SIz volumes, and URz/SIz shared volumes.

Table 23 on page 82 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 (e.g., 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 thehostquery to thespeciﬁc 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.
