  We have a 4-node RAC cluster with about 4-5 databases running.  These are
M4000 Solaris 10 - 4CPUs - 64 GB - 8 processors

  Last time when the sysadmins rebooted the machines, they complained that
powering up and rebooting the node 4 panics all the other nodes, and the crs
is going down in all the other nodes.  They can't give any other details.
So, they have kept the node 4 powered off to keep the other 3 nodes running,
and they suggest that node 4 be removed from the cluster. Even the removal
of the node they want to do it but they want us to teach them how to do it,
as we do not have "sudo /bin/bash" priv.

databases are at
crs is at

1.   Did anyone have this kind of problems, where 'powering on one node'
panics all the other nodes with regard to crs?
2.   Does the "Addition/Removal of nodes from the clusters fall under DBAs'
activities, or sysadmins' activities?
