Fdisk and format show different cylinders can't use whole disk for solaris?

Question

Solaris 10 5/09 s10x_u7wos_08 X86
Format did not show enough cylinders, so we can't use whole raid5 (4x 146GB) volume.
How can we fix it? We need the full raid5 volume for our solaris.

Hi Smart71,
I know it sounds complicated, but it really isn't.
You need to select the option to manually edit the disk label
when you install solaris.
Your problem is that you have assigned 73 GB for your / (root)
and 63 GB for your swap. That's not the problem that I see. The problem is that the Solaris partition (and therefore the Solaris VTOC label inside) is only for 136GB. But the actual underlying storage is 409GB. So the entire partition and the VTOC have to be rewritten.
You only have 2 options. Either re-install Solaris, of re-partition the disk.
If you don't have a spare disk to copy root to and you want to use
the whole disk, with just one / root partition, you will need to shrink /swap
create another slice to copy root to temporarily, and then re-partition your disk. Agreed reinstalling is easiest. But moving slices around will not let you change the VTOC size.
eg:
boot from CD into single user mode.
partition the disk so that eg:
swap is 3 GB. eg: ( from cylinder 1 to cylinder 400 )
partition 3 is 7 GB ( from cylinder 401 to cylinder 1318 )
( if 7 GB is enough to hold all your / data )
write the disk label out
newfs partition 3
mount / on /a
mount partition 3 on /mnt
Copy everything from /a to /mnt eg:
rsync -vaxH /a /mnt
or
find /a -xdev -print | cpio -pdam /mnt
umount /a and /mnt
re partition the disk so that / takes all the free space.If that were your goal, you wouldn't have to move anything. Just repartition and use 'growfs' on the root filesystem directly (while booted from CD).
eg ( starting at cylinder 1319 to cylinder 17816 )
write disk label out
newfs part 0 for /
mount / on /a and part 3 on /mnt
copy everything back from /mnt to /a
Check /a to make sure everything is there.
umount /a and /mnt
re partition the disk to make /swap 10 GB
( starting at cylinder 1 to cylinder 1318 )
write disk label out.
And that's it.
The disk you are working on is 17816 cylinders in size.
yet down the bottom you say that :
Total disk size is 53502 cylinders
That tells me there are 4 disks in the raid 5 set, and that
you have probably been presented with 3 x 136 GB disks.
That means that you should have 2 x 136 GB disks free.
Use one of these to copy your /root to. and then
re-partition your first disk and copy data back.
Or partition another disk correctly, write a boot block to it
Copy your root data to it, and boot from it.The entire disk is presented to the machine (as seen in the fdisk output), but the Solaris partition is only using the smaller portion of it. You can't create a second Solaris partition and use it at the same time, either. Only one Solaris partition can be used at a time.
