Unable to understand disk layout and where are the free space
Hi

I am unable to understand the disk layout of one of my disk attached to v240. This is newly installed system from jumpstart.

I am unable to see the free space on backup slice 2 and there are 0 to 8 slices listed when I run format and print the disk info, also there is no reference of slice 7.

Please find the output from format
Code:
#echo |format

Searching for disks...done


AVAILABLE DISK SELECTIONS:
       0. c0t0d0 <SEAGATE-ST373307LSUN72G-0507-68.37GB>
