Rebooting 3 to 1 Cluster nodes.
hello Gurus,
My current set up is 3 to 1 Cluster (SUN Cluster 3.2) running oracle database. Task is to reboot the servers. My query is about the procedure to do the same.
My understanding is suspend the databases to avoid switchover. Then execute the command scshutdown to down the cluster and i'll be at OK prompt. Please help with the correct procedure.
Thanks in advance.

commandlog
commandlog(4) Sun Cluster File Formats commandlog(4)
NAME
commandlog - command log file
SYNOPSIS
/var/cluster/logs/commandlog
DESCRIPTION
The commandlog ASCII text file contains records of selected Sun Cluster commands that are executed in a cluster. The logging of commands
starts automatically when you set up the cluster and ends when you shut down the cluster.
Commands that are not logged in this file include those that display the configuration and current state of the cluster. Commands that are
logged in this file include those that configure and change the current state of the cluster, as follows:
o claccess
o cldevice
o cldevicegroup
o clinterconnect
o clnasdevice
o clnode
o clquorum
o clreslogicalhostname
o clresource
o clresourcegroup
o clresourcetype
o clressharedaddress
o clsnmphost
o clsnmpmib
o clsnmpuser
o cltelemetryattribute
o cluster
o scconf
o scdidadm
o scdpm
o scgdevs
o scrgadm
o scshutdown
o scswitch
Each record in the commandlog file contains the following information:
o Date and timestamp
o Host name from the which the command was executed
o Process ID of the command
o ID of the user who executed the command
o Command that the user executed, including all options and operands
Note -
Command options are quoted in the commandlog file to enable you to copy, paste, and execute them in the shell.
o Exit status or signal of the executed command
By default, the commandlog file is regularly archived at the end of every week. Sun Cluster maintains up to eight previously archived com-
mandlog files on each cluster node at any given time.
