clustermode automatic login (from linux) to systemshell of clusternode

On clustermode: You have configured automatic login for the clustershell
On linux: You have installed expect (# yum install expect expectk)

create an expect script.
mind you: grcm1 is my clustername and gr-01 is
the name of my first clusternode.

$ vi direct
#!/usr/bin/expect
spawn ssh admin@grcm1 set advanced \; node systemshell -node gr-01
expect "login:"
send "diag\r"
expect "Password:"
send "diagpassword\r"
send "sudo bash\r"
send "id\r"
interact

(end script)

$ chmod +x direct
$ ./direct
spawn ssh admin@grcm1 set advanced ; node systemshell -node gr-01
