Figure 24 SIz T-VOL in Split Status Functioning as URz Primary Data Volume
If a failure occurs and the SIz S-VOL is damaged in
“SIz T-VOL in Split Status Functioning as
URz Primary Data Volume” (page 69)
, take the following steps to copy data from the URz
secondary data volume to the SIz S-VOL so that data can be restored to the SIz S-VOL:
1.
Execute the Business Continuity Manager YKDELETE command on the SIz pair to release the
pair (see
“Restoring a SIz S-VOL - Step 1” (page 69)
).
2.
Execute the Business Continuity Manager YKSUSPND REVERSE command on the URz pair to
suspend the pair. After that, execute the YKRESYNC REVERSE command to reverse the copy
direction and re-establish the pair (see
“Restoring a SIz S-VOL - Step 2” (page 70)
).
3.
Execute the Business Continuity Manager YKSUSPND FORWARD command on the URz pair
to suspend the pair. After that, execute the YKRESYNC FORWARD command to change the
copy direction to the original direction and re-establish the pair (see
).
4.
Execute the Business Continuity Manager YKSUSPND command on the URz pair to suspend
the pair (see
“Restoring a SIz S-VOL - Step 4” (page 70)
).
5.
Execute the Business Continuity Manager YKMAKE command on the SIz pair to perform
copying in the reverse direction (see
“Restoring a SIz S-VOL - Step 5” (page 70)
).
6.
Execute the Business Continuity Manager YKDELETE command on the SIz pair to release the
pair (see
“Restoring a SIz S-VOL - Step 6” (page 71)
).
7.
Execute the Business Continuity Manager YKMAKE command on the SIz pair to perform
copying in the original direction (see
“Restoring a SIz S-VOL - Step 1” (page 69)
).
8.
Execute the Business Continuity Manager YKSUSPND command on the SIz pair to put the pair
in Split status (see
“Restoring a SIz S-VOL - Step 8” (page 71)
).
9.
Execute the Business Continuity Manager YKRESYNC command on the URz pair to resynchronize
the pair (see
“Restoring a SIz S-VOL - Step 9” (page 71)
).
