Because the goal is to simulate a crash on the Primary, do not use IBC Messaging for trial failover.
To pause the RLINK on the Primary, type:
# vxrlink -g hrdg pause rlk_london_hr_rvg
To pause the RLINK on the Secondary, type:
# vxrlink -g hrdg pause rlk_seattle_hr_rvg
# vxrvg -g hrdg -P trial snapshot hr_rvg
where trial is the prefix for the snapshot plexes for all data volumes. Snapshot data volumes with names trial-hr_dv01 and trial-hr_dv02 are created.
# vxrlink -g hrdg resume rlink_name
where rlink_name is the name of the paused RLINK.
# fsck -F vxfs /dev/vx/rdsk/hrdg/trial-hr_dv01 # fsck -F vxfs /dev/vx/rdsk/hrdg/trial-hr_dv02
# vxrvg -g hrdg -P trial snapback hr_rvg
The -P option to the vxrvg snapback command reattaches to the original volume the plexes with the prefix specified when taking the snapshot.
