I have a Sol x86 box attached to NexSAN SATABoy via a switch.
Mistakingly I have built a 500MB LUN instead of 500G LUN. I have
resized it in SATABoy, but format still shows it as a 500MB disk
device.

I've tried devfsadm, but to no avail.. Any hints?

Thanks!

Try running format, select your disk, choose type -> auto configure
(normally option 0), then label the disk.  You should get the correct
size then.

That should be sufficient for SPARC, but this is an x86 box.  'format'
isn't going to change the fdisk partition.  I don't know if fdisk needs
to reset anything or if it can read the new geometry dynamically.

I'd start with fdisk, something like 'fdisk /dev/rdsk/c0t0d0p0'.  It
should show what it thinks is the size of the disk in cylinders.  If it
looks appropriate for your size, delete the existing solaris partition,
then create a new "full disk" solaris partition.
