Explanation
While trying to create a table of available dump
volumes, an error occurred. The conditions under which DFSMShsm creates
the table are:
- At DFSMShsm start
up during initialization of the dump control task
- When the activity against dump volumes is high enough to warrant
a refresh of the contents of the DVST
Note: The last condition occurs only when the SELECTVOLUME(SPECIFIC)
parameter was specified on the SETSYS command.
The values for
retcode are:
- Retcode
- Meaning
- 8
- While trying to access the control data set for dump volume information,
more than five I/O errors occurred. See the accompanying ARC0184I
or ARC0187I message.
- 10
- While trying to access the DVL records in the control data set,
a positioning error occurred. See an accompanying ARC0187I message.
- 52
- The GETMAIN macro returned a nonzero return code when DFSMShsm attempted
to get more virtual storage for the dump volume selection table. It
is possible that too many volume backup, volume dump, or volume space
management tasks were running concurrently. It may be necessary to
reduce the number of concurrent tasks by using the SETSYS command
with the MAXBACKUPTASKS, MAXDUMPTASKS, MAXMIGRATIONTASKS, or MAXINTERVALTASKS
parameters. Retry the volume functions that ended with this error.
System action
This dump volume selection fails to find a specific
volume, which causes the selection of a scratch tape volume. The next
specific selection attempt tries to build the table again.
Programmer response
- For return code 8, take the action indicated in message ARC0184I.
- For return code 10, take the action indicated in message ARC0187I.
- For return code 52, it is possible that too many volume backup
tasks, space management tasks, or volume dump tasks, were running
concurrently. It may be necessary to reduce the number of concurrent
tasks by using the SETSYS command with the MAXBACKUPTASKS, MAXMIGRATIIONTASKS,
MAXINTERVALTASKS, or MAXDUMPTASKS parameters. Retry the volume functions
that ended with this error.
