Working on OO based system administration
What a day for commuters.
It was really messy today when I was driving along 404 southbound.

There were 5 accidents and traffic was so jammed up. I would prefer to work from home if I can choose. Thanks.

Create 50 SAN Volumes in 1 minute
I was asked to setup a mixed SAN infrastructure with both fiber and iSCSI SAN products. One of the requirement is to create over 50 of the volumes. It will be tedious and time consuming if going through the GUI one click at a time so I decided to give it a try using CLI and some ruby code to help.
50.times { |x|
puts "volume create Tables#{x+1} 100G pool bigsan"
puts "volume select Tables#{x+1} access create ipaddress 10.1.1.*"
}
