    Marianne - how did you got a clue on BCV's ?

    As this is a normal file system backup I still don't understand how this work specifying the raw devices.

    Testing the raw read speed can be done by:

    time dd if=/dev/rdsk/c33t0d5 bs=256k of=/dev/null count=10000

    output;

    10000+0 records in
    10000+0 records out

    real       18.2
    user        0.0
    sys         0.1

    #  echo "256*10000/18" | bc

    142222 KB/sec

    On the media server please tell if NUMBER_DATA_BUFFERS & SIZE_DATA_BUFFERS files are located in /usr/openv/netbackup/db/config

No. The client name is NOT eux380. Look at Client name in the policy:

Client/HW/OS/Pri/DMI:  eux390....

So, it seems you are taking BCV snapshots that are mounted on the media server, right?

Check SAN configuration -
are all LUNs mapped to a single HBA?
Are tapes on media server mapped to same or different HBAs?
(Hopefully NOT 31 tape drives added to single media server!)

Good thing you have disabled TIR backup for raw filesystem backup.

Oh - about multiple backup jobs - the policy is configured for 4 streams with MPX in the schedule allowing 3 simultaneous jobs.

Buffer size and 'waits' can be seen in bptm log on the media server.
Log folders do not exist by default - create them under /usr/openv/netbackup/logs.
