Examples---Off-Host Processing

The examples in this chapter assume that the following VVR configuration has been set up on the Primary and Secondary hosts:

Name of the Primary host: seattle

hrdg

Disk group

hr_rvg

Primary RVG

rlk_london_hr_rvg

Primary RLINK for Secondary london

hr_dv01

Primary data volume #1

hr_dv02

Primary data volume #2

hr_srl

Primary SRL volume

Name of the Secondary host: london

hrdg

Disk group

hr_rvg

Secondary RVG

rlk_seattle_hr_rvg

Secondary RLINK for Primary seattle

hr_dv01

Secondary data volume #1

hr_dv02

Secondary data volume #2

hr_srl

Secondary SRL volume

The examples use the application name dss_app for sending and receiving IBC messages.


For Example 1, Example 2, and Example 3, perform the following steps before you begin:

  1. Create a snapshot plex on the Secondary for each data volume using the command:
      # vxassist -g hrdg snapstart hr_dv0l
      # vxassist -g hrdg snapstart hr_dv02

    You can use the -b option with the vxassist snapstart command to run the command in the background. Note that if you use the -b option of the vxassist snapstart command, you must wait for the snapshot plexes for all the data volumes in the RVG to be created and synchronized completely. When the plex synchronization completes, the output of the vxprint command displays the state of the new snapshot plex as snapdone.

  2. If you have bought a license for FastResync (FR) use the command:
      # vxvol -g hrdg set fmr=on hr_dv0l
      # vxvol -g hrdg set fmr=on hr_dv02
