Hi All,
As far as I know, I need to present the vmware datastore LUNs to Netbackup media server (also vmware backup host) to backup the virtual machines over SAN. My media server (also backup host) is Windows 2008 R2. Question is that, are these LUNs must be online or offline in the Disk Management? By default, the LUNs are coming offline. Do I have to make them online or leave offline.
By the way, I ran "automount disable" and "automount scrub" commands in diskpart.

The LUNS will typically be ONLINE and HEALTHY as is. But do NOT write a signature or volume name or assign a drive letter. Just leave them unlabeled, online and healthy.
Basically when running the diskpart commands as you did, zone the disks to your host, that's it typically. You could even go as far as making the LUN read-only for that NBU host. I've done it before and it works for backups. Restores had to have some extra steps involved, or use NBD.

You mean if I leave the LUNs offline, I can backup virtual machines from SAN but can not restore them from SAN. If I want to perform SAN restore, I need to make the LUNs online. Is that right?

What @teiva-boy is saying is that, as he suggested read only access to the presented LUN, you will not be able to write a restore back to that LUN via SAN. If you don't make the LUNs RO, then you have already done everything you need (other than making sure the backup policy uses SAN connectivity). Making the presented LUN read only is only a suggestion, rather than a requirement.
Cheers,

How do you make the LUNs read-only or read-write? I can only make the LUNs online or offline from the Windows Disk Management. offline is equal to read-only and online is equal to read-write ?

You would normally set the status of the LUNs (rw or ro) from within SAN management software, not from within Windows.
