Failaover time more than 1 minute

Hi,

I have a Veritas cluster 6.1 configured on Red Hat 6.4, and it is taking more than one minute to failover even though no agents are configured yet.

The only resources configured are the Disk Groups and Mounts. The cluster is not generating any errors, still it takes a very long time either in deporting the Disk Group or in importing it, sometimes even volumes take long time to go online.

At first, the cluster service had only one disk group as a resource, and the failover time was around 25 sec, but when I added another disk group, failover time increased to 1.5 to 2 minutes.

Any advice what might be causing this slowness?

Thanks
