Add File-System: Mount FileSystem in Global Zone:
zonecfg:nidoz3> add fs
zonecfg:nidoz3:fs> set dir=/opt
zonecfg:nidoz3:fs> set special=/nidoz4_1/opt
zonecfg:nidoz3:fs> set type=lofs
zonecfg:nidoz3:fs> set options=rw,nodevices
zonecfg:nidoz3:fs> end

Remove a FileSystem in Non-Global Zone
global# zonecfg -z zonename
remove fs dir=/usr/local/mysql/data

To get the Non-Global Zone Information:
# cat /etc/zones/nidoz3.xml
Or
zonecfg:nidoz1> info
Or
# zoneadm list –cv
Or
# zonecfg -z nidoz1 export

To Set the IP Address for Non-Global Zone
ifconfig e1000g0:3 plumb 137.72.420.420 netmask 255.255.255.0 zone nidoz3 up

To Delete a Non-Global Zone:
# zoneadm list –cv
# zoneadm -z nidoz3 halt
# zoneadm list –cv
# zoneadm -z nidoz3 uninstall
# zoneadm list –cv
# zonecfg -z nidoz1 delete
# zoneadm list –cv

expect scripting

Nice way to start expect would be to first visit: http://expect.nist.gov/

Expect is mainly used to automate the task for some applications which require manual interaction such as telnet, ftp, passwd, fsck, rlogin, tip, etc.

Enough of the introduction part for expect.


Example(1): will telnet to a host named as `nido` it'll put login and password credentials and then will surely can run either of the commands ( I know, one command will fail)...

_______________________________________________

#!/usr/local/bin/expect
spawn telnet nido
expect "login"
send "root\r\n"
expect "Password:"
send "whoami\r\n"
expect -re {\#}
send "/usr/contrib/bin/machinfo| mailx parwatraj@yahoo.com/r"
expect -re {\#}
send "ls -l\r"
expect -re {\#}
send "/opt/ignite/bin/print_manifest| mailx parwatraj@yahoo.com/r"
expect -re {\#}
exit
_______________________________________________________
Example(2): will telnet or ssh to a list of hosts which are in a text file `/script/testpnhost.txt` and will do the same task as we've seen on the above example.
Excute testpn4 and see how it works for you.
Modify the contents of expect script as per your need.

---------------------------------------
# cat testpn4
#!/bin/sh
for A in `cat /script/testpnhost.txt`
do
echo ${A}
echo "__________________________"
/script/testpn5.exp ${A}
done
---------------------------------------------------------------

# cat testpn5.exp
#!/usr/local/bin/expect
spawn telnet [lindex $argv 0]
expect "login"
send "root\r\n"
expect "Password:"
send "whoami\r\n"
expect -re {\#}
send "/usr/contrib/bin/machinfo| mailx parwatraj@yahoo.com/r"
expect -re {\#}
send "/opt/ignite/bin/print_manifest| mailx parwatraj@yahoo.com/r"
expect -re {\#}
exit
