How to re-create RVG

I have mistankly deleted 2 disks that were used as cachevol for secondary RVG and data in secondary become unaccessible, for that i went through deleting the DG and succeeded.

now i am trying to create RVG group again, for that i should delete both RVG in main and DR which seems impossible, even dissociate SRL volume from primary RVG seems impossible

any hint please?

    Steps are freeze replication group on both nodes and then on SYS1 run

    1. vxrlink -g DB2hrDG dis rlk_SYS2-rep_DB2-rvg 
    2. vxrlink -g DB2hrDG det rlk_SYS2-rep_DB2-rvg
    3. vxedit -g DB2hrDG rm rlk_SYS2-rep_DB2-rvg
    4. Look at flags in vxprint -Vl - (lowercase L on end) and if RVG is a primary  then run:
      vradmin  -g DB2hrDG delpri DB2-rvg

      else if RVG is a secondary then run:

      vxrvg -g DB2hrDG  stop DB2-rvg (may need to use -f)
      vxvol -g DB2hrDG dis <vol_name> for each of the volumes in the RVG (all volumes in the diskgroup including the SRl -so example):
      vxvol -g DB2hrDG dis SYS1_DB2_DB1 

      Then:
      vxedit -g DB2hrDG rm DB2-rvg
       
    5. Now can create your RDS as normal using:
      vradmin createpri
      vradmin addsec
    6. And start replication
      vradmin -a startrep
       

    For steps 6 and 7, these are not full commands, but if you type them as above they will give you the syntax - example:

    # vradmin createpri
    VxVM VVR vradmin ERROR V-5-52-19 Incorrect number of arguments
    VxVM VVR vradmin INFO V-5-52-37
        Usage: vradmin [-g diskgroup] [-nodcm] createpri rvg vol1,vol2,... srl

    Let me know if you need any more help for steps 6 and 7.

    hi Mark,

    when executing the delpri command i got the below messages:

    Message from Primary:
    VxVM VVR vradmin ERROR V-5-52-533 Primary RVG DB2-rvg is started. Use force option -f to override.

    should I use the -f option, does this affect any of the mounted volumes? i dont wanna VVR to go down on the primary too so Oracle goes down too

     

    thanks
