iostat command in Solaris

One of the best commands during audits without tearing open a physical Solaris box is iostat. What I usually use it for is the finding out size of drives and type:

iostat -En command will give you the size of the devices that are connected via the io interface.

So everything from hard drives to optical drives. It gives you not only the size of the drive, but it also tells you the vendor, and serial numbers. This makes it extremely easy to find out how many drives are connected in your system and the total space there. It also allows you to see if there are drives that are failing with errors so you know if you have to replace anything.

Got to love friendly commands like this which are the difference between servers and workstations.
