Celerra FC Connections to servers for tape backup of NS FileSystems?
Can someone help point me in the right direction on this? I'm looking for documentation on how to set up a tape drive library so that I can backup the Celerra File Systems. My Celerra has front end FC ports. How do I connect this to a SAN switch, how should it be zoned? Can someone point me in the right direction on this? When i look it up, i find a lot of info about using the Celerra as a VTLU, but I don't want to backup to the Celerra, I want to backup from the Celerra to a tape library. Any help on this?
Thanks.

Good morning.
I am attaching the 2 NDMP documents we have. One is for backup to disk.
The server_iscsi command has a -p (probe) and -l (list) switch. The '-list' is to see what's currently configured or written to your camdisk files. The '-probe' is to see what's being presented to the DM.
A good command to run is the following: 'server_devconfig server_X -p -s -n' -n for non-disk devices.

your datamovers have aux ports, so you will zone your tape drives/robot to these aux ports. After you will need to rescan for new drives:
server_devconfig server_2 -create -scsi -all (substitute server_2 for your datamover). Datamover can only support 4 concurrent NDMP jobs so i would not present more than 4 drives.

Thanks Dynamox.
After you perform a rescan, how does the tape drive show up? Where do i go on the Celerra Manager to see it?
Is there a document that describes how to do it?
Basically what I want to do it backup different file systems to tape. But I have no idea where to look. Is that what NDMP backups are for? When I read about those it seems that the Celerra is backup device, but i don;'t want to backup to the Celerra, I want to backup FileSystems on the Celrra to tape. So that if my Celerra fails, I have backups of the filesystem on tape. Can you tell me what document I can look at that describes how to do it? I don't see anything in the Celerra Manager of how to do it?
Thanks.

Hi,
I would suggest to start with the
Configuring NDMP Backups on EMC Celerra
manual available from Powerlink.
It explains the various NDMP connectivity options and how you can see your tape through server_devconfig.
What backup application are you using ?

That document looks promising.
I'm trying to read up on using the NDMP backup to a Commvault server with a tape drive.
Thanks.

if i run this command on my datamover "server_devconfig server_2 -list -scsi -nondisks" , the output looks like this:
so you can easily identify your tape drives, in my case they are IBM tape drives (virtual tape library)
