Hello experts,
I have a netbackup 5240 appliance running v3.1. This 5240 appliance acts as Master/Media/Backup Host for VMware.
I am very new to appliances and networking. I want to be able to perform VMware backups over the SAN to the appliance.
Here is what I did so far:
Do I also need to zone the VMware Datastores (LUNs) with the appliance fiber ports on the SAN switches? If yes, does this mean that each zone has 1 LUN and 2 appliance ports (1 from each slot)?
I also read somewhere that I need to run the following commands on the Media Server before zoning:
Are these commands necessary on my appliance which is Master/Media? If yes, how can I run them?
I know I'm missing some configuration, I just don't know what.
I kindly need your help. Thank you very much in advance!!

Why do you want to use iSCSI?
Do you have a model H Appliance? Please see attached pdf. Only model H comes with iSCSI.
you really only need to zone one or more 8G FC HBAs configured as Initiator.

Extract:
You can use the Initiator ports for tape-out operations and VMware Datastores
Herewith short overview of steps:

Also, on a side note, I checked the fiber ports' status from the Appliance CLI and here is the output:
----------------------------------------------------------------------------------------------------------------------------------------------------------------
Bus ID Slot Port Port WWN Status Physical State Configuration Type Speed Remote Ports
06:00.0 Slot5 1 21:00:00:24:FF:15:F9:70 Disconnected Target Target(FTMS) 0 gbit/s ------------
06:00.1 Slot5 2 21:00:00:24:FF:15:F9:71 Disconnected Target Target(FTMS) 0 gbit/s ------------
07:00.0 Slot6 1 21:00:00:24:FF:18:3B:D0 Disconnected Target Target(FTMS) 0 gbit/s ------------
07:00.1 Slot6 2 21:00:00:24:FF:18:3B:D1 Disconnected Target Target(FTMS) 0 gbit/s ------------
----------------------------------------------------------------------------------------------------------------------------------------------------------------
Is this behavior normal? Or do I need to manually enable them? What is the command to do so?
Please forgive me for all these questions. I don't anywhere else to go for help.
Have a nice night/day and thank you so much :D

No, this is not correct. VMware VADP SAN Transport backups do not utilize Fibre Transport Mode. You need the ports to be in initiator mode.
How familiar are you with NBU Appliances? I ask for where to direct you. If you already understand the basic concepts and setup, take a look at the Appliance Fibre Channel Guide. It explains how to use the appliance for VMware backups. If you're not, start with the Config Guide and Admin Guide to understand some of the more basic operational aspects.

Hi vtas_chas,
Thank you for your reply.
I know the basic concepts about the appliance. However, I am not familiar with SAN and fiber. I have read some parts of the Appliance Fiber guide but honestly I did not understand what I needed to do (I think it's because it's my first time working with SAN/fiber).
If I choose "2 target port Fibre Channel connection" instead of 4, will that solve my issue?
Do I need to do some other configurations? And what about the automount commands mentioned in my earlier reply?
In the mean time, I will re-read the Appliance Fiber Guide and do some additional research. Will post back if I find anything.
Thanks again!

Hi Marianne,
Thank you for your reply. I already have the 3.1 documents but thanks anyway :D :D

No you need ZERO FTMS ports. VADP backups do not happen over FTMS target ports, you are connecting to the datastores as an initiator. Do not touch the automount or disk partitions at the operating system. You need to read the VMware admin guide as well to get an understanding of how VMware SAN Transport backups work as well.
Honestly, I wouldn't try to do this over a web forum. There are many concepts here that you are going to need help with including fundamental NBU details, VMware backup details and appliance details. I'd strongly suggest engaging a Veritas partner or Veritas consulting to help you get this deployed.

I think I got it. NetBackup for VMware on a 5240 appliance works over iSCSI and not FTMS (In my case the appliance is the backup host). Please tell me if the below is right.
Thanks in advance :D
And sorry for any inconvenience.
