NOTE: Status display is the same as the CQUERY TSO command.
Example: DEVSERV Command
NOTE: The symbol “-” indicates that the combination is impossible.
Splitting Pairs: CSUSPEND and PPRCOPY SUSPEND
The CSUSPEND and PPRCOPY SUSPEND commands are equivalent to the SI390 split pair operation
(changes pair status to SP-pend). The following are examples of the CSUSPEND command and PPRCOPY
SUSPEND commands. These commands must be issued to the S-VOL and the pair status must be duplex.
For information on the optional QUIESCE parameter for the CSUSPEND TSO command, see ”CSUSPEND
QUIESCE Parameter” on page 87.
