Cause

 [ EXPLANATION ]

There are 2 ways Solaris discovers the disk characteristics.
- The first way is to query the disk (to see if the firmware got the disk info already)
- The second one is by reading a label on the disk.
 
Format is used to read a disk label and the issue was it reported error messages below;
The current rpm value 0 is invalid, adjusting it to 3600
