To dump all the volumes in one or more storage groups, use the
command:
BACKVOL STORAGEGROUP(sgm) DUMP
The processing for dumping each volume in a specified storage group
is the same as explained in
Dumping a volume. As in that case,
there is an additional available option for stacking dump copies as
shown in the following example:
BACKVOL STORAGEGROUP(sgn) -
DUMP(DUMPCLASS(class,class,...,class) STACK(nn,nn,...,nn))
You can specify a stacking value, as follows:
- In the STACK parameter on the BACKVOL command
- If the STACK parameter is not specified on the BACKVOL command,
in the definition of the dump class specified on the BACKVOL
- If the DUMPCLASS parameter is not specified, in the definition
of a dump class associated with a specified storage group
If the stacking value is greater than 1, DFSMShsm stacks up to nn dump
copies on the dump volumes of the dump classes used.
