SRM, SRA, Celerra, iSCSI
Hi all, i've got another problem.
When i test a recovery plan with SRM it failed because my Celerra NS-120 take too much time to make the snapshot, Promote and GRANT.
I try the recovery plan on a small iSCSI LUN (300go) it works fine; but when i try on a big LUN (2 To) it failed because the SRA don't find at time the snapshot.
the log here :

The snapshot is create but it take time, and when the SRA try to promote the Snapshot-LUN and make the GRANT it don't find it beacause the Celerra is not ready.
So, I try to increase the timeout in SRM, it doesn't work.
Have you got any idea ?

I've got more informations, the error come from this command :
I create the snapshot of my iSCSI LUN
[nasadmin@SAN-S1-NS120 ~]$ server_iscsi server_2 -snap -create -target SAN-S1-NS120-iSCSI1 -lun 201 -data 'SRM-TEST-FAILOVER'
server_2 :
Info 26306936878: OK.id=fs145_T7_LUN201_CKM001050001510000.ckpt016
But when I try to make a promote to my esx server, it doesn't work
[nasadmin@SAN-S1-NS120 ~]$ server_iscsi server_2 -snap -promote fs145_T7_LUN201_CKM001050001510000.ckpt016 -initiator iqn.1998-01.com.vmware:vmw-s1-esx1
server_2 :
Error 13159038988: Resource is unavailable.
It works fine if i wait about 3 minutes after i create the snapshot.
[nasadmin@SAN-S1-NS120 ~]$ server_iscsi server_2 -snap -promote fs145_T7_LUN201_CKM001050001510000.ckpt016 -initiator iqn.1998-01.com.vmware:vmw-s1-esx1
server_2 :
OK
But i can't make a pause in the SRM script, so this error block my recovery test.
Any idea ?
