765.0. "Urgent!! Trucluster + OPS + raw" by DEKVC::DONGHWANJUNG () Wed Mar 12 1997 06:14

    Hi all
    
    I am trying to set up a Trucluster ASE and OPS for LSM raw devices
    to use with Oracle7. Of course, this is due to my customer needs.
    My customer will be use Trucluster and OPS with LSM raw devices. 
    Therefore, They will be use raw data backup with NSR DMO. And then
    there is one problem to use raw backup procedure. My customer want to
    use command procedure - like macro or bat - to split and join with LSM
    s/w mirring.
    
    I'd like know LSM procedure to each use split and join only one command
    procedure as bat-file-type. and I'd like know how take time compare
    with filesystem backup when I use raw data backup.  
            
    Frankly speaking, I'm curious for how is this acomplish and take time.
    
    Following is my customer configuration:
    
    =========================================================================
    ASE1 : 8400 5/440*2 (2GB)     ASE2: 8400 5/440*2 (2GB)

    	   LSM 4.0                      LSM 4.0

           OPS 1.4                      OPS 1.4
           NSR DMO 1.X                  NSR DMO 1.X

    Volume configuration : 30 volumes ( VOL01 ~ VOl30 )
   ---------------------------------------------------------------------------
    
   This is command procedure for LSM + filesystem to split and join 
                                 ---------------
   for example)

    I should know how to raw backup procedure.
      
      - first, be split raw lsm volume and mount other mount-point.
      - 2nd , backup and reconfiguration raw lsm volume.
    
    
    Please tell me about raw data backup command procedure with LSM as soon
    as possible.
    
    Best regards.

    Hi Jung,

    Wwhile you can well disssociate a plex from your RAWw volume and
    associate that plex to a new RAW volume, there is NO MOUNT POINT
    involved in raw device used by Oracle. So, ythe split volume concept
    cannot be used by DMO.

    Dear devos,
    
    Thank you your answer !
    
    O.K, I know all. But I should know raw backup command procedure.
    
    Please send me about raw data backup command procedure with LSM as soon
    as possible.
    
    Best regards.

    Hi
    
    >> Please send me about raw data backup command procedure with LSM...
    
    ???   LSM as such, does NOT provide raw data backup procedure. DMO is
    working only in cooperation with ORACLE, and if you split one volume
    into one original and one snapshot volume, Oracle is not aware that you
    have now a new "snapshot" volume, thus DMO CAN NOT backup that
    "snapshot" volume.

    Hi !
    
    Thank you your kindness.
    
    O.K !! I will not use DMO.  But, I should know how to backup raw data with 
    OPS(Oracle Parallel Server). Is there any available method without DMO ? 
    Already, my customers baught OPS and TL826 device. and then I should support
    them. 
    
    Please send me how to backup raw data in any available methods ASAP.
    
    Best regards.

    Hi,
    
    You should better ask in the BELFST::ORACLE notefile how ORACLE is
    suggesting to backup the raw device.
