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

       The command displays the amount of free disk space available either on the specified filesystem for example) or on the file system in which
       the specified file (such as is contained.  If no file system is specified, the free space on all of the normally mounted  file  systems	is
       printed.  The reported numbers are in kilobytes.

       The command recognizes the following options:

	      Display information regarding file system swapping.

	      Report the number of used and free inodes.

	      Display information for local file systems only (for example,
			     HFS and CDFS file systems).

	      Do not sync the file system data on the disk before reporting the usage.
			     Note that the data reported by may not be up to date.

       The command does not account for any disk space reserved for swap space, or used for the HFS boot block (8 KB,  1  per  file  system),  HFS
       superblocks (8 KB each, 1 per disk cylinder), HFS cylinder group blocks (1 KB - 8 KB each, 1 per cylinder group), and inodes (currently 128
       bytes reserved for each inode).	Non-HFS file systems may have other items not accounted for by this command.
