Re: [Veritas-bu] Anyone using media sharing in 6.5?

I got a response from my Symantec rep, and here's what he said:

"It was just a warning. If you are using ACSLS access control, you need to make sure that all the NBU media servers in the NBU media share group have the same ACSLS access permissions on the media in the ACSLS database. Kind of obvious, but it’s actually been a minor issue in regular NBU running without media sharing."

If it's this simple, why couldn't that have been put in to the manual? Anyway, I'll be implementing this feature in the next week or so and will report back on how it goes.

I could see some problems if your ACSLS setup has watch_vols going (all tapes are not visible to all servers automatically). Enabling Media Sharing across all media servers could then open the door to NetBackup requesting a tape mount on a server that can't actually see that tape maybe.

Not something I've seen, just a possibility.

I was just looking over this last night, and was surprised it's not on by default....
I also ran across a statement in the guide that said you should use caution with ACS libraries, but I could not tell why you needed to be cautious. Anyone have an idea?

Subject	[Veritas-bu] Anyone using media sharing in 6.5?

I'm finding that I'm vaulting quite a few partially used tapes, because each tape can only be written by the server that owns it, and I have 7 media servers. The new media sharing option in 6.5 looks like it would help to optimize the tape usage, but I'm wondering if anyone has tried this out yet? I checked the knowledge base and there are several bugs related to media sharing that are fixed in 6.5.2 (which I am using). Just a bit nervous to enable this in production. I'm also wondering where a shared tape is mounted for a restore...is it based on the server that the image was written on, since there would be no overall tape "owner"? We use alternate restore server options quite frequently, so I don't want to break that. Any comments on media sharing would be greatly appreciated.
