and/or secondary sites. Table 22 (page 72) describes the host pair status reporting for Universal
Replicator for Mainframe volumes, ShadowImage for Mainframe volumes, and Universal Replicator
for Mainframe/ShadowImage for Mainframe shared volumes.
Table 23 (page 72) shows the
currency of the data on a shared Universal Replicator for Mainframe/ShadowImage for Mainframe
volume based on the Universal Replicator for Mainframe and ShadowImage for Mainframe pair
status.
•
For shared Universal Replicator for Mainframe/ShadowImage for Mainframe volumes, the
Universal Replicator for Mainframe pair status is reported to the host if you query the Universal
Replicator for Mainframe primary data volume or secondary data volume. To obtain the
ShadowImage for Mainframe pair status, query the target volume (T-VOL) of the ShadowImage
for Mainframe pair.
•
ShadowImage for Mainframe supports multiple T-VOLs for each source volume (S-VOL). If you
issue a pair status query to a ShadowImage for Mainframe S-VOL (for example, pairdisplay),
the status for only one ShadowImage for Mainframe pair is reported (the pair with the T-VOL
with the lowest LDEV ID). To obtain the pair status for the ShadowImage for Mainframe 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 ShadowImage for Mainframe remote console software
displays the port, TID, LUN, LDEV ID, and ShadowImage for Mainframe pair status for all
T-VOLs associated with an S-VOL.
