Switching services from active node to failovernode in cluster
Hi All,
I was asked to Switch the service from failover to active node as we need to reboot active node for regular maintenance. Unfortunately our senior admin left the organization. It would be helpful if some one answer this query. Detailed info with steps will be appreciated.
Here are the below details. I need to reboot lab1 and need to switch all services to lab2 or lab3.
I believe the /appfs is related to cluster. I'm bit rusty with cluster administration
Please help!!!
Code:
#hostname
lab2
#clustat
Member Name Status
------ ---- ------
lab1-int Online, rgmanager
lab2-int Online, Local, rgmanager
lab3-int Online, rgmanager
Service Name Owner (Last) State
------- ---- ----- ------ -----
app_gfs_svc lab2-int started
app_prod lab1-int started
app_test (lab1-int) disabled
app_upgrade (none) disabled
# df -TPH /appfs
Filesystem Type Size Used Avail Use% Mounted on
/dev/dm-50 gfs 32G 24G 8.3G 75% /appfs

This post was from a while ago, but i'll answer in case anyone finds this in a search looking for an answer.
The short answer is that there is nothing you need to do. If you shut one down the services should fail over automatically. The command to move a rgmanager service from one host to another is:
Code:
clusvcadm -r <service> -m <new_member>
For example:
Code:
clusvcadm -r app_prod -m lab3-int
All of this assumes that the services have been configured correctly and with best practice.
Setting up HACMP 6.1 on a two node cluster. The other node works fine and can start properly on STABLE state (VGs varied, FS mounted, Service IP aliased). However, the other node is always stuck on ST_JOINING state. Its taking forever and you can't stop the cluster as well or recover from script... (2 Replies)
