Hi,

I have EMC Data Domain here and a remote one and I am doing replication between 
them. TSM is v5.5.6.100 on AIX, so is the Storage Agent on both end. The files 
backup also on AIX, file client is v6.2.4.4. These are file backups.

To prepare for a restore on the remote location:
  - previously has copied the rootvg (AIX) couple of days ago (DB and LOG disks 
has not changed), remote virtual library and drives were avaiable
  - copied the DB and LOG disks after the backup (SVC replication)
  - copied VOLHIST and DEVCONFIG to the appropriate directory
  - changed DSMSERV.OPT, added DISABLESHEDS YES and NOMIGRRECL
  - opened the TSM and using a script disable sessions, deleted sheds, disk 
pool volumes, paths, drives, libraries, redefined the virtual library and drives

When I tried to do a test restore for a small file (there a 5 of them and 42 of 
the big ones), there is failure and it says cannot find the file, on TSM it 
says cannot mount read-only cartridge (the cartridges are READWRITE on TSM, but 
on VTL there are RORD - Read Only / Replication Destination), I tried all kind 
of stuff but couldn't get thru, so I deleted the replication pair relationship 
and then it worked. After starting the restore with 12 concurrent sessions, I 
saw the following:

The cartridge which is mounted R/W is the same one which was requested before, 
It contains all of the small files and pieces of 2 big ones.

My question is why a restore will require cartridge to mount R/W ? The pools on 
the destination side of VTL replication are R/O, and only deleting the pair 
relationship will make the R/W, but I don't want to do it again.

Tuncel
