Nsrstage case study for cloned savesets in EMC Networker (Research)

Here is a Little piece of research I did on the Networker for the SSID & Clone ID's

Case 1 : original save set -------> clone --------> stage
created tape for the Default group and Default clone group. both have separate tapes assigned to that pools.
now i created 1g file and wrote it to the default tape group.
save -b Default /tmp/1g.file
mminfo -q "name=/tmp" -r ssid,cloneid,nsavetime
note the ssid and clone id.

Now we will clone this saveset to the default clone pool
mminfo -q "volume=<>" -r ssid,cloneid,nsavetime
mminfo -q "volume=<>" -r ssid,cloneid,nsavetime
compare the ssid for both the conditions

Now relabel the default tape to make it blank.
nsrstage the default clone pool to the default pool
note the ssid,cloneid for the staged pool
mminfo -q "volume=<> -r ssid > 1.txt
nsrstage -v -b Default -m -S -f 1.txt
mminfo -q "<>" -r ssid,cloneid
compare it to the default clone one to see whether there is change or what?

1) after save
mminfo -q "Name=/tmp/1g.tmp" -r ssid,cloneid,nsavetime
ssid clone id save time
3219192121 1289812281 1289812231

2) after cloning
mminfo -q "volume=AZ0061L4" -r ssid,cloneid,nsavetime
AZ0061L4 - Default group

ssid clone id save time
3219192121 1289812281 1289812231

mminfo -q "volume=AZ0059L4" -r ssid,cloneid,nsavetime
AZ0059L4 - Default clone group

ssid clone id save time
3219192121 1289836444 1289812231

3) after staging
mminfo -q "volume=AZ0061L4" -r ssid,cloneid,nsavetime

ssid clone id save time
3219192121 1289837524 1289812231

mminfo -q "volume=AZ0059L4" -r ssid,cloneid,nsavetime

6095:mminfo: no matches found for the query

Case 2 : original save set --------------> stage
Create 2 tape for the default group.
Now create the 1g file and write it to Default group.
note the ssid and cloneid for this
stage this to this another tape.
again note the ssid,cloneid for both tapes and verify what changes

1) after save
mminfo -q "name=/tmp/1g.tmp" -r ssid,cloneid,nsavetime --------> AZ0061L4

ssid clone id save time
3084999581 1289837469 1289837417

2) after staging
mminfo -q "volume=AZ0059L4" -r ssid,cloneid,nsavetime -------------> AZ0059L4

ssid clone id save time
3084999581 1289838604 1289837417

mminfo -q "volume=AZ0061L4" -r ssid,cloneid,nsavetime

6095:mminfo: no matches found for the query
