    David,
   =20
         The only trick is, when creating the partition with the =
/etc/format
    utility, do not include cylinder 0 (zero) in the partition intended =
for use
    as a raw partition. Also on Solaris 2.5.1 partition must be LESS =
than 2 gig
    in size.

         I apologize that information is not in the pubs. I was certain =
that
    was added last revision, but I just check and it is not.

    Jim,

    We've never been able to get ADSM to recognize raw volumes in a =
non-AIX
    environ.  Any tricks I'm missing here?  This would be good news for =
us - we
    prefer raw volumes.

    Malkit,

         Try setting, in dsmserv.opt,  DISKMAP NO.  This setting can =
improve
    performance with larger disk pools and with some disk sub-systems. =
To get
    the best disk storage pool performance on Sun, we recommend using =
the
    raw-partitions (see the reference manual or the help on "define vol" =
and
    the notes on the disk device class).

    Hello
   =20
    We have Solaris ADSM server v3.1.2 , with the following options in
    dsmserv.opt :
   =20
    BUFPoolsize 20480
    EXPInterval 24
    MOVEBatchsize 1000
    MOVESizethresh 500
    TCPNodelay yes
    TCPWindowsize 0
    TXNGroupmax 256
    USELARGEbuffer yes
    USELARGETAPEBLOCK yes
   =20
    The backup is done to disk stg pool. We get bad performance on =
backing
    up and restore as well. Attach are two of the worst performance =
during
    the night backup.
    I will appreciate your experience on tunning the ADSM server and
    clients. We get better performance when doing selective/incremental
    backup directly from the client, but still it doesn't get to =
1mb/sec.
    Awful !
