B) Log in as a cluster services administrator.
Bring the member on "pscale1" to quiesce mode and stop the cluster caching facility.
Bring the member on "pscale1" to maintenance mode.
Bring cluster caching facility on "pscale1" to maintenance mode.
C) Log in to "pscale1" as a DB2 instance user.
Bring the member on "pscale1" to quiesce mode and stop the cluster caching facility.
Stop the instance on "pscale1".
Log in as DB2 cluster services administrator.
Bring "pscale1" host to maintenance mode.
D) Log in to any of the hosts as root user.
