ESX LUNS

[NavGee]

Hi is there a command I can run on the the netbackup appliance to view all the wwn's for ESX luns presented to the backup host appliance?

I'm pretty sure that would only show the wwn's of the hba's not the wwn's for the LUN's presented to the appliance.

That depends on when you run it.  The LUNs aren't permanently mounted to the appliance, only the snapshot LUN is during the backup.  So if you run it while there are no backups running, you are partially correct.  It will show you the WWNs of the ports you're connected to as well as the WWNs of the HBAs.  If you run it during a backup, you should see the LUNs.

The above explanation sounds like VCB, I thought with NBU 7.6 the processes are as follows:

(direct write from the datastore to the storage unit are you saying that the during the snapshot phase the datastore is mapped to the backup host please clarify? )

Phase 1

The NetBackup master server initiates the backup.

Phase 2

The NetBackup client on the VMware backup host initiates a VMware
snapshot on the virtual machine.

Phase 3

Windows: VSS synchronizes the file system on the virtual machine.
Linux: The SYMCquiesce utility can quiesce the file system on supported
Linux operating systems.

Phase 4

The VMware server creates a snapshot on the virtual disk datastore.

Phase 5

The NetBackup client reads the snapshot from the datastores and writes
the data to the NetBackup storage unit.
