San client backup says: FT client has no devices configured

Hello All,

Trying to setup san client backup together with my media server.
What i did already

1. Zoning, san client with storage and hba are zoned together with media server hba,

2. San client enabled for system that has storage connected.

3. Configured new backup policy.

When i start the backup:

awaiting resource advanced-disk-stu - FT client has no devices configured

Looks like i have missed something here...

I do have an advanced disk configured with slp that is used for direct san backup (on a different hba) for my esx setup (and working fine0.
Is this setup conflicting on 1 media server?
