unquiescescripts and copy them to the
/etc/vx/vvr/ibc_scripts/dss_appdirectory on the Primary host.
quiesce script, provide commands to put the application that is using the Primary data volumes hr_dv01 and hr_dv02 in quiesce mode.
unquiesce script, provide commands to resume the application or take it out of the quiesce mode.
onfreezescripts and copy them to the
/etc/vx/vvr/ibc_scripts/dss_appdirectory on the Secondary host.
prefreeze script, include the following commands to add snapshot plexes to the Secondary data volumes hr_dv01 and hr_dv02:
/usr/sbin/vxassist -g hrdg snapstart hr_dv01
/usr/sbin/vxassist -g hrdg snapstart hr_dv02
onfreeze script, include the following command to take the snapshot of the Secondary volumes:
/usr/sbin/vxrvg -g hrdg snapshot hr_rvg
This example does not need a
ibccommand from any host in the RDS:
vradmin -g hrdg ibc hr_rvg dss_app london
SNAP-hr_dv02to run the DSS application, that is, for off-host processing.
vxrvg -g hrdg snapback hr_rvg
The snapback destroys the SNAP volumes and reattaches the snapshot plexes to their original volumes. If you have enabled FR on these volumes, the reattach is faster.
