[Veritas-bu] NDMP question (drive sharing)

Mark,

To share regular drives between filers, you will need netbackup 6.

Subject: [Veritas-bu] NDMP question (drive sharing)

I've been crawling the NDMP manual for an hour but haven't found a 
black-and-white answer yet.

I have a number of Netapp Filers and we're looking at implementing NDMP backups 
(we currently just backup NFS mounts).  I know I cannot share a set of drives 
between my NDMP hosts & my other media servers.  We're OK with the idea of 
carving out a set of drives exclusively for NDMP backups (yes, I know about 
v6.0 - we're not quite ready to convert yet).

What I can't figure out is if a single SAN-connected drive can be shared 
directly with more than one filer.  I can see that if I do a 3rd-party NDMP 
backup, the a single NDMP host can be used to backup the others.  I'd rather 
not load one filer or media server with the backups of another.  I'd like the 
blocks to go as directly to media as possible.

The drive setup seems to specify which NDMP host has direct access to the 
drive, I guess to do what I want, I'd have to define the same robotic drive on 
more than one NDMP host.  My initial goal is to remove 4 drives from my regular 
drive config & share them between the 7 filers, each grabbing any drive as 
required.

Baring this, an option would be to define a directly attached drive for each 
filer, utilizing more drives, then build storage unit groups where each filer 
would use their own storage unit first, failing to another 3rd-party host only 
if their drive is already too busy.  So, can NDMP storage units be grouped?

For those with v6.0, are your SSO sharing your drives with your filers and 
how's it working out?
