Host access to EMC storage snapshots
Our goal is to snapshot a Clariion LUN and mount the snapshot on RHEL 5 Linux server.
We follow the following procedure
naviseccli -h snapsview -createsnapshot -snapshotname
naviseccli -h storagegroup -addsnapshot -gname -snapshotname
naviseccli -h snapview -startsession -snapshotname
naviseccli -h snapview - activatesnapshot -snapshotname
When we try fdisk -l, storage snapshot device is not seen. How do we determine the device name of the storage snapshot that
was activated?
thanks,
Paddy

Have you tried doing this manually? Starting the snapshot and then activating in Navisphere Manager, then a partprobe to see if the new 'lun' is there. If you're using Qlogic fiber cards, Qlogic has a utility to rescan the adapter to find new LUNs on the fly.
Once you find if that works, you start looking at how to script it.
