Do the following steps, it wont allow change on client
Problem:
User home directory is owned by someone else. Changing permission is not allowed.
[root@aigunx225 ~]# ls -ld /home/weblogic
drwxr--r-- 2 nobody webgp 4096 Jun 21  2010 /home/weblogic

[root@aigunx225 ~]# chown -R weblogic:webgp /home/weblogic
chown: changing ownership of `/home/weblogic': Operation not permitted
restarted autofs still problem

Solution
Get the nfs share info
[root@aigunx225 ~]# df -h /home/weblogic
Filesystem            Size  Used Avail Use% Mounted on
aignas2:/vol/aignas512/appserv2/weblogic
                      200G  124G   77G  62% /home/weblogic

[root@aigunx225 ~]# id weblogic
uid=7253690(weblogic) gid=75154(webgp) groups=75154(webgp)

Mount same nas on homeserve01 or he2unx171 and then change the ownership.
On appserv02 server,
# mkdir /tmp/xyz
# mount aignas2:/vol/aignas512/appserv2 /tmp/xyz
# cd /tmp/xyz
# ls -ld weblogic
drwxr--r--   2 100325   webgp    4096 Jun 21  2010 weblogic
# chown -R weblogic:webgp weblogic
drwxr--r-- 2 weblogic webgp 4096 Jun 21  2010 /home/weblogic
Now, login to the client machine and verify.
[root@aigunx225 ~]# ls -ld /home/weblogic
drwxr--r-- 2 weblogic webgp 4096 Jun 21  2010 /home/weblogic
[root@aigunx225 ~]#

make sure umount the nas after your done your change
on appserv02,
# umount /tmp/xyz
# rmdir /tmp/xyz

Shutdown the multiple server using the Blade Logic script

1. The script
#!/opt/bladelogic/NSH/bin/nsh
# How to user it
# create a file with list of servers and save on the same dir as this file is.
# run this script on a blade logic server.
# ./server_shutdown.nsh --check file_with_list_of_servers
USER_CHOICE=$1
SERVER_FILE=$2
if [ -z $USER_CHOICE ]
then
    echo usage: server_shutdown.nsh --check  {file_with_list_of_servers}
    exit 0
fi
if [ -z $SERVER_FILE ]
then
    echo usage: server_shutdown.nsh --check  {file_with_list_of_servers}
    exit 0
fi
if [ ! -f $SERVER_FILE ]
then
    echo file $SERVER_FILE does not exist
    echo please check and try again
    exit 4
fi
if [ "$USER_CHOICE" = "--check" ]
then
    for i in $(cat $SERVER_FILE)
    do
        echo
        echo "======================================================="
        echo shutting down $i
# For Linux server shutdown
        nexec $i shutdown -h now
# For solaris server shutdown
        nexec $i 'init 5'
    done
    echo

else
    # no valid choice
    echo usage: server_shutdown.nsh --check  {file_with_list_of_servers}
fi

he3unxdv512
he3unxdv513
he3unxdv514
he3unxdv515
he3unxdv516
he3unxdv517

3. how to use it?
