- session_id
- Specifies the name of an XRC session. The name you specify can
be any name acceptable to TSO that matches the name of a session previously
specified on the XSTART command, except for the word ALL, which is
reserved. The maximum length of the name is eight characters. Do not
include embedded blanks. TSO ignores leading blanks and trailing blanks.
- VOLUME
- Specifies the volume serial numbers of the primary and secondary
volume pairs you want to add to an XRC session. Use either a blank
or a comma to separate each primary and secondary volume serial number
within each pair and to separate the pairs. The VOLUME parameter is
mutually exclusive with the SUSPENDED parameter.
- XRCUTL
- Specifies that the system data mover can use the primary volume
as a utility volume for a storage control session. This means that
a utility volume is not shadowed to a secondary
volume when the secondary volser specified is XRCUTL.
Specifying
XRCUTL in conjunction with the UTILITY parameter on the XSET command
determines the type of device (fixed or floating) that XRC uses to
read data from a storage control.
When you specify XRCUTL, XRC ignores the NOCOPY, DONOTBLOCK,
ERRORLEVEL, FULLCOPY, and QUICKCOPY options.
- SUSPENDED
- Specifies that XRC adds all suspended volumes back into the
session and schedules them for resynchronization. This parameter
is mutually exclusive with the VOLUME, DONOTBLOCK, NOCOPY, SCSESSION,
ERRORLEVEL, FULLCOPY, and QUICKCOPY parameters. Suspended volumes
keep the same characteristics that existed when the suspension occurred.
Note: Do not use this option to add volumes back into the session
if you plan to change any of the volume pair characteristics (such
as error level, session assignment, or blocking assignment)
