Did you change the polices to use a new storage unit on the new library
or are the still set to use storage units on the old library?

Subject: Re: [Veritas-bu] Strange problem after changing storage unit.

1. So you took the tapes from the L1000 and put them into an SL24?

No, The new unit is LTO3 and we have brand new tapes with new barcodes. 
The reason i have restored catalogue is so we have historic data. My 
idea was to hook up the L1000 when we transfer this server down, 
configure it and then be able to restore from it, but not use it to
backup

2. I am assuming the media servers did not change?

Just a simple master/media in one box. With some remote network clients.

Currently i'm building this in the lap so have E220 connected via scsi 
to SL24 with 2 x LTO3 drives and 20 odd LTO3 tapes with new barcodes.

3. Did the drve tapes stay the same?

No. The new tapes are hcart3 and the old ones are DLT. The policies have

changed to use new storage unit, but i wasn't aware you needed to change

tape types at all?

4. Did you inventory the library and make sure the media is scratch?

Yeah inventory all works and matches up with physical. The new volume 
group 00_000_TLD sees tapes in correct slots.

5. Is the barcode reader in the new robot inventorying the tapes the
same
   way as the old one?

New altogether.
