This technical note will define an initial implementation of a VVR (SRVM) primaryand secondary.

Configuration:

Primary system:  scrollsaw
Secondary system:  palday
Primary and Secondary RVG name:  testrvg
Primary and Secondary volume name:  testvol
Primary and Secondary SRL name:  srlvol
Primary to Secondary Rlink:  to_palday
Secondary to Primary Rlink:  to_scrollsaw

Before starting:
Verify that a remote shell works from each system to the other.

On Secondary:
1. Make the data volume:

vxassist -g <disk group> make <data volume> <size>

    ex. vxassist -g testdg make testvol 1g

2. Make the SRL volume (use a different disk, don't put in rootdg, must be mirrored)

vxassist -g <disk group> make <SRL volume> <size> mirror=1

    ex. vxassist -g testdg make srlvol 1g mirror=1

3. Make the RVG:

    vxmake -g <disk group> rvg <RVG name>
    ex. vxmake -g testdg rvg testrvg

4. Make the rlink:

vxmake -g <disk group> rlink <local rlink name>

    ex. vxmake -g testdg rlink to_scrollsaw

5. Set the attributes on the Rlink:

vxedit -g <disk group> set remote_host=<remote system> remote_dg=<remote disk group> \
remote_rlink=<remote rlink name> <local rlink name>

    ex. vxedit -g testdg set remote_host=scrollsaw remote_dg=testdg remote_rlink=to_palday to_scrollsaw

6. Associate the datavol, SRL, and Rlink with the RVG:

vxvol -g <disk group> assoc <RVG name> <data volume>

    ex. vxvol -g testdg assoc testrvg testvol

vxvol -g <disk group> aslog <RVG name> <SRL volume>

    ex. vxvol -g testdg aslog testrvg srlvol

vxrlink -g <disk group> assoc <RVG name> <local rlink name>

    ex. vxrlink -g testdg assoc testrvg to_scrollsaw

7. Add DCM to volume:

vxassist -g <disk group> addlog <data volume>

    ex. vxassist -g testdg addlog testvol

8. Attach the Rlink to the RVG:

vxrlink -g <disk group> att <local rlink name>

    ex. vxrlink -g testdg att to_scrollsaw

9. Start the RVG:

vxrvg -g <disk group> start <RVG name>

    ex. vxrvg -g testdg start testrvg

On Primary:
1. Make the data volume:

vxassist -g <disk group> make <data volume> <size>

    ex. vxassist -g testdg make testvol 1g

2. Make the SRL volume (use a different disk, don't put in rootdg, must be mirrored)

vxassist -g <disk group> make <SRL volume> <size> mirror=1

    ex. vxassist -g testdg make srlvol 1g mirror=1

3. Make the RVG:

vxmake -g <disk group> rvg <RVG name>

    ex. vxmake -g testdg rvg testrvg

4. Make the rlink:

vxmake -g <disk group> rlink <local rlink name>

    ex. vxmake -g testdg rlink to_palday

5. Set the attributes on the Rlink:

vxedit -g <disk group> set remote_host=<remote system> remote_dg=<remote disk group> \
remote_rlink=<remote rlink name> <local rlink name>

    ex. vxedit -g testdg set remote_host=palday remote_dg=testdg remote_rlink=to_scrollsaw to_palday

6. Set the attribute on the RVG (default is secondary):

vxedit -g <disk group> set primary=true <RVG name>

    ex. vxedit -g testdg set primary=true testrvg

7. Associate the datavol, SRL, and Rlink with the RVG:

vxvol -g <disk group> assoc <RVG name> <data volume>

    ex. vxvol -g testdg assoc testrvg testvol

vxvol -g <disk group> aslog <RVG name> <SRL volume>

    ex. vxvol -g testdg aslog testrvg srlvol

vxrlink -g <disk group> assoc <RVG name> <local rlink name>

    ex. vxrlink -g testdg assoc testrvg to_palday

8. Add DCM to volume:

vxassist -g <disk group> addlog <data volume>

    ex. vxassist -g testdg addlog testvol

9. Attach the Rlink to the RVG to Autosync:

vxrlink -g <disk group> -a att <local rlink name>

    ex. vxrlink -g testdg -a att to_palday

10. Start the RVG:

vxrvg -g <disk group> start <RVG name>

    ex. vxrvg -g testdg start testrvg
