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
# 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.
# vxvol -g hrdg set fmr=on hr_dv0l # vxvol -g hrdg set fmr=on hr_dv02
