Hello all,
These are the steps that i'm following to switch back a resource managed by
the MRSL.NONsharedDevice agent:
Scenario: Did occur a failover (the system is in logging mode), the resource
is running on the secondary node.
Steps (commands):
1 - Bring the resourcegroup offline (clresourcegroup offline pool-rg)
2 - Do a reverse/update sync (sndradm -C local -g POOL -n -r -u)
3 - Here we have two options using the NONsharedDevice agent:
a) Put the AVS software in logging mode again (sndradm -C local -g POOL
-n -l) or
b) Set the Last_Started extension to the "primary" node hostname
(clresource set -p Last_started=primarynodename pool-rs)
4 - Bring the resourcegroup online on the primary node (clresourcegroup online
-n primarynodename -M pool-rg)
The question is:
While the systems are resync the services are unavailable, the good point is
that is a switch back scenario, so we can schedule it. But would be nice if i
could make a reverse/sync while still using the resourcegroup. I mean, if there
is a lot of data to resync, can be a long, long maintenance time.
Thanks very much for your time!
Leal.
