Unable to understand disk layout and where are the free space


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
#echo |format

please don't use QUOTE tags for code... just use the CODE (# in editor) tags!

for your question:
your disk has an EFI disk label. you can change the label by running "format -e" and choose "label" and then the "SMI" label.

I see, because of the missing code tag, I couldn't read. Got it now

something is not right, which disk was selected before you used the prtvtoc table? 0 or 1 ? Unlikely that it is 0, the first disk right?

Thanks Duek!

When I am trying to label the disk I am getting the below error

partition> label
  Unable to get current partition map.
  Cannot label disk when partitions are in use as described.

Not sure if I have followed your instructions! Executed the format -e option and select the disk 0 then I tried labeling. Is that what you mean or I am doing it wrongly.
