man nsrmm:
-e time
When used in conjunction with the -S option, it sets
the retention time of the specified save set. The
retention time should be specified in the format that
is acceptable to the function nsr_getdate(1m). Note
that once the save set becomes recyclable, the reten-
tion time may not be changed. The save set retention
time may not be set such that the save set would become
recyclable while it is still browsable. Refer to the
-w option for more details on browse time. When used
in conjunction with volumes, the volume labeled will be
an Archive volume if the value of time is forever
(Archive volumes mean that the volume label never
expires). Any other value of time are not applicable
to a volume.
-S ssid
Changes ( -o) or removes ( -d) a save set from the Net-
Worker databases, or used in changing the browse time
(specified with -w) or the retention time (specified
with -e) of the specified save set record. The save
set is identified by a save set identifier, ssid. A
save set instance, or clone, can be specified using the
format ssid/cloneid (but, it is ignored when used for
the options -w and -e). The mminfo(1m) program may be
used to determine save set and clone identifiers.
so what would be the scenario
list all candidates from the disk volume (pool)
and for each set the expire time
( note the restriction on browsetime so you may have to set that too )
with:
mminfo -xc/ +AFw- # sets separator to / for ssid/cloneid
-q' ,pool=<disk pool>,...and lets say copies=2' +AFw-
-r'ssid,cloneid |
grep -v ssid | # to get rid of the labels from mminfo
while read a
do
echo y | nsrmm -e <new time> -w <brose time> -S +ACQ-a
# this specifies both ssid and cloneid and so only targets
# the disk copy
done
Hope this gives you some idea
