Disk Setup Issues
•When selecting disks to partition, be careful not to select your internal disk.
•To support third-party failover software products on dual controller single loop SANs, SAN Manager devices are listed twice as available disks when you run the Format utility. If you are using a dual controller single loop SAN, be careful to partition, create a file system, and mount only one instance of each SAN disk. For example, if c1 and c2 are the Fibre Channel controllers, then c1t17d0 and c2t17d0 refer to the same disk. If you partition, mount, or create file systems on both instances of a disk, data corruption will occur.

1.Run the Format utility.
A list of available devices appears with a prompt to specify a disk. The following example is sample output from a one controller, one loop SAN configuration:
