Networker server config with 2 storage nodes and only 2 drives

Question

Scenario:I recently purchased a Celerra Ns120 and a Scalar i500 with 2 LTO4 drives. I own a NDMP license to backup data to the scalar, a storage node licenses, and a autochanger license. The Networker Server is Linux not windows. In the past i have always used the Celerra as my FC backend, but this time I purchased a FC switch.

Goal: I would like to use 1 drive in the scalar to backup the data on the celerra and 1 drive for the networker server to back up traditional nw clients.

From my Celerra created an ndmp user name ./nas/sbin/server_user server_2 -add -password ndmp

I created the devices server_devconfig server_2 -create -scsi -nondisks and list them. From the celerra i see 2 tape drives and the jukebox

Now the interesting part. From the Networker server I run the inquire command. The output shows me 2 tape drives and a jukebox. I'm thinking I should only see 1 tape drive here and a JB. Is that accurate? At the same token, from the Celerra should i see both drives and the jukebox?

I currently zoned the Networker server to the Celerra DM2, NW Server to Celerra DM3, NW Server to Scalari500, Scalari500 to Celerra DM2, Scalari500 to Celerra DM3

DM3 is a failover DM only.

The i500 is in a single partitioned config with 86 slots.

Problem:I am unable to connect to the celerra via the inquire -T -N celerra from the nw server.

When I run the inquire command from the NW Server i see all my devices. Should I see the tape drive from the NW Server without the inquire -T -N Celerra command? I'm thinking that something is not zoned correctly, cabled or partitioned correctly. Do I need to change the way the Scalar is cabled to itself or does what I am saying sound correct?

Thanks

I also have i500 with Celerra.  To translate config to yours, you should zone 1 drive and robotic to server and 1 drive to Celerra.  With i500 wwnn used is the one given out by I/O blade so this may be confusing at the start.  When configured, inquire -cl on server should show 1 robotic and and 1 drive while inquire -N will show you second drive on Celerra.

Hi, If you want to manage one drive with NW server and other with Celerra, you'll need to zone each drive ONLY with your manager. Otherwise, you'll still seeing two drives at NW server side. Regards

Ideally you should have 2 zones. One with the Celerra and the jukebox/tape drives and one with the NetWorker server and the jukebox/tape drives.

In other words, your jukebox overlaps into both zones and all Celerra's are on in zone and all NON Celerra's are in the other zone. Servers are initiators,

tape drives/robotics are targets. Separate the Celerra into a zone away from the NW server and all other hosts and then overlap the tape drives into both zones.

Hope that helps.
