ShadowImage for Mainframe Operations
This section describes the main operations for ShadowImage for Mainframe.
Set Reserve Attribute Operation
The ShadowImage for Mainframe set reserve attribute operation reserves a volume so that it can
be used as an SIz T-VOL. Reserved volumes can only be used as SIz T-VOLs. The XP storage system
rejects all write operations to reserved volumes (unless in Split or V-Split status). You can reserve
up to 16,384 volumes in one XP storage system.
When TSO or ICKDSF commands are used to establish SIz pairs, the T-VOLs do not need to be
reserved. The CESTPAIR and PPRCOPY ESTPAIR commands require that potential T-VOLs be offline
to the host. For details, see
(page
93).
Add Pair Operation
To create (add) an SIz pair, the volume, which will be the S-VOL, must be in the simplex state. You
may set reserve attribute on the T-VOL before adding it to an SIz pair. You can also create a pair
with an unreserved simplex volume. For detailed information about how to create SIz pairs, see
"Adding Pairs" (page 70)
When you create a new volume pair, initial copy starts and all the data in the S-VOL is copied to
the T-VOL.
