Hi,

in report you can see all snap session on a CU bye issue the command
QUERY VOLUME(UNIT(2000))

If you want to make a short list on only 16 volumes issue the command
QUERY VOLUME ( UNIT(2000) CCUU(2000:201F) SESSION_LIST(YES,DETAIL) ) .

The results if these commands gives you source volume and target volume.

To stop snap activity on a target volume issue the command stop on target volume
STOP SNAP TO VOLUME ( TARGET(UNIT(5000)))

and cleanup on source volume
CLEANUP EXTENT TRACK ON UNIT(2000)

example : result of query command is

0060(2000) P5LGRA STD CKD-03339 READY RAID/5 SNAP-SRC
SESSION TARGET TRACKCNT PROT-TRK IND-TRK P
25EF 14DD(2800) 50085 0 0
04FF
04FE
0061(2001) P5LGRB STD CKD-03339 READY RAID/5 SNAP-SRC
SESSION TARGET TRACKCNT PROT-TRK IND-TRK P
25EF 14DE(2801) 50085 0 0
04FF
04FE


to stop snap on volser P5LGRA ( ucb 2000 , symdev 0060) isssue:

STOP SNAP TO VOLUME ( TARGET(UNIT(2800)))
CLEANUP EXTENT TRACK ON UNIT(2000)

Hope this help you. If doesn't work, you can call technical EMC support and they can stop all snap sessions if tou want this.

Thanks, but my query volume report does not show any source-target relationships. It appears to be orphaned sessions. I'm wondering if these are residual sessions when we moved to this box (DMX4) from the SHARK via EMC's product LDMF. We had to force LDMF off our system when we ran out of time during the migration. Does anyone know of a way to cleanup orphaned sessions?

Hi,

i've no answer by a emc utility and don't know . So contact technican inspector to analyse the box by remote maintenance and he can clear this. I think it's the best way to solve your problem on snap sessions.

nice day to you.
