We have some scripts set up that perform the creation, activation and termination of some VP Snap sessions. These run at 6hr intervals and are controlled by crontab on a remote server. Once the session is active it stays active for 2 days. Then after 2 days the next scheduled job will run and it will terminate the current session and re-create a new one.

The problem i have is we have some existing device files and need to append on to it some new source/target pairs into them but if i do that the scripted termination fails and then of course the re-creation of a new session fails because the termination has not killed the old session.

So for example we currently have this device file;

[emcscr@ukbbpssspxy01 device_files]$ cat DF_BACKUP_23

#Src  Tgt

01C39 0200D

01C07 02003

01C08 02004

01C05 02005

01C06 02006

01C76 0205F

01C7E 02067

01C66 0202F

01537 02017

And you can see there is an active session running for it;

[emcscr@ukbbpssspxy01 scripts]$ symclone -sid xxxx -f /appl/emc/device_files/DF_BACKUP_23 query

And what i need to do is add a new device pair into the device file so it is included the next time this session is created. I know i can add the pair detail into the device file but the existing session will not terminate if i do that because the device file contains a pair that is not in an active session.

So does anyone have any ideas on how i can add this pair and let the scripted termination and then creation scripts still control everything? Or is it simply a case of i have to manually terminate the existing sessions, edit the device files and then manually restart the session or leave it to the scripts to start it when its next scheduled?

Any assistance, thoughts and ideas would be appreciated
