Linux Cluster failover issue
Hi Guys,
I am not much aware of clusters but i have few questions can someone provide the overview as it would be very helpful for me.
How can i perform cluster failover test to see all the services are failing back to other node ? If it is using veritas cluster then what kind of pre-prequisite i need to follow ?
If it is not using veritas cluster then how to check whether host is clustered or not ? if clustered how can i perform failover to other nodes?
If my question is not clear please forgive me and let me know what are the required steps i need to follow this procedure ?
Thanks

hb_takeover
HB_TAKEOVER(1) General commands HB_TAKEOVER(1)
NAME
hb_takeover - issues a failover request to the cluster manager
SYNOPSIS
hb_takeover [all|foreign|local|failback]
DESCRIPTION
Warning
This command is deprecated. It is only suitable for legacy Heartbeat clusters without Pacemaker enabled. In Pacemaker-enabled clusters,
the crm(8) shell supports switching individual nodes into standby mode, and replaces hb_takeover.
/usr/share/heartbeat/hb_takeover issues a request to the cluster to move resources to the node where it is invoked, from the other node.
Issuing hb_takeover on the current node is equivalent to performing hb_standby on the other node.
CAVEATS
hb_takeover is only usable in R1-style configurations (i.e., those configured using the haresources file).
SEE ALSO
hb_standby(1), heartbeat(8), cl_status(1)
