Assure MIMIX for AIX

The snapshot journal space can be increased on the recovery server without impacting the production environment. To increase the Snapshot Journal space on the recovery server:

  1. Stop Assure MIMIX for AIX on the recovery server.

  2. Unmount any snapshot file systems.

    /usr/scrt/bin/rtumnt -C <Context ID>

  3. Release a snapshot if it exists.

    /usr/scrt/bin/scrt_ra -C <Context ID> -W

  4. Stop Assure MIMIX for AIX.

    /usr/scrt/bin/rtstop -C <Context ID> -Fk

  5. Use rtattr to increase the size of an existing snapshot journal volume.

    Note: Any snapshot journal can be increased in size since all snapshot volumes are available for use during snapshot creation/use.
  6. Determine the name of the snapshot journal to increase.

  7. Use the following command to find the snapshot journal volume sizes:

    /usr/scrt/bin/rtattr -C <Context ID> -t SCRT/containers/WJournal -a Size

    The ObjectName of a snapshot volume that you want to increase.

  8. Select one of the snapshot journals and increase the size of the volume.

    /usr/scrt/bin/rtattr -C <Context ID> -o <ObjectName> -a Size -v <new size value in bytes>

  9. Find the logical volume name for the snapshot journal.

    rtattr -C <Context ID> -o <ObjectName from step 8 on page 229>-t SCRT/containers/WJournal -a FileName

  10. Remove the existing snapshot journal volume that you want to increase

    rmlv -f <ObjectAttributeValue from step 9 on page 229 minus the /dev/r prefix>

  11. Create the new snapshot journal volume.

    /usr/scrt/bin/scsetup -C <Context ID> -M

  12. Restart Assure MIMIX for AIX.

/usr/scrt/bin/rtstart -C <Context ID>
