How to create a snapview snapshot on an existing LUN

Posted by on May 8, 2017 No comments

I apologize in advance for this (6 years or so too late) post, since it’s for creating a snapview snapshot on a LUN on a VNX. It’s simply meant as a reminder for the command line syntax:

Examples for creating snapview snapshots (it only defines it, no COFW is happening at this point):
naviseccli -h 172.16.20.96 snapview -createsnapshot 17 -snapshotname VMFS-001-SNAP
naviseccli -h 172.16.20.96 snapview -createsnapshot 18 -snapshotname VMFS-003-SNAP
naviseccli -h 172.16.20.166 snapview -createsnapshot 27 -snapshotname VMFS-002-SNAP
naviseccli -h 172.16.20.116 snapview -createsnapshot 5 -snapshotname VMFS-004-SNAP

To start an actual point in time session (and the start of COFWs):
naviseccli -h [ip address] snapview -startsession [session name] -snapshotname VMFS-001-SNAP

To stop a session:
cnaviseccli -h [ip address] snapview -stopsession [session name]

To activate a snapview session (make the data visible):
naviseccli -h [ip address] snapview -activatesnapshot [session name] -snapshotname VMFS-001-SNAP

To deactivate a snapview session (stop presenting the data to the hosts):
naviseccli -h [ip address] snapview -deactivatesnapshot [session name] -snapshotname VMFS-001-SNAP
