Go to SolutionAttaching a RDM for Replication Manager for Exchange DB recovery
Hi All,
we have Exchange 2007 running on VMware Infrastructure, on Windows 2008VM
Replication Manager is used as a backup solution.
It is working fine.
But I have some questions on the set up.
We attach RDMs from the Storage (which is VNX7500) , we attach the RDM LUN snapshots as RDMs rather than LUN itself. (Atleast I think so)
Why is that?
I was told, this is because while mounting a replica, these RDMs are used to mount the DB there, i.e the mount happens on the RDM.
And I was told this is because we have selected for the LUN visiblity in the Replication Manager while restoring.
I am bit confused on all these, can someone please clarify?
Regards,
A
Hi All,
From the admin Guide,
When you create a replica that uses CLARiiON snapshots in a
VMware environment, Replication Manager creates a snapshot
session. The snapshot session is a point-in-time copy of the source
LUN.
To mount this snapshot session, you must create a snapshot device.
The snapshot device is the handle used to access the contents of the
snapshot session.
For a mount host to access a snapshot session, the following
prerequisites must be met:
Is this the reson?

Hi there Athreya -
You are absolutely correct.
It is not a requirement of Replication Manager or any software, more how ESX kernel wants have an understanding of the underlying characteristics of the snap LUN (aka device), PRIOR to EMC activation the snapshot session ontop of the device.
Thanks!
