Partition/Format USB drive on Solaris 10

[Joshua Boyd]

What is the trick for doing this?  prtconf clearly sees the USB drive
and says it is sd15, but rmformat and format both refuse to see it.

I do have vold running.  I have created /rmdisk. I think the drive in
question has a ext2fs on a partition, which I need to replace with UFS
or ZFS.

My notes are at the office, but we did this last summer -- and it does work!
On Monday I will look it up. I'm pretty sure it's UFS, but I forget the one
"trick" about it.

   If you can't wait for me, look for that German (?) Sun lab video with the
dozen USB drives demonstrating how awesome ZFS is: perhaps there's a clue
there.

I believe that you really only need to rn `mkfs -F pcfs` on the little
fellow. Here, read this longer-winded blog post:

   Here's making a flash drive bootable for an x86 Sol 10 system:

   I know we did it on a T2000. Let me know how you make out!

OK, rmformat shows me nothing.

>From the log and prtconf, I can see that my USB drive is showing up as
c1t0d0, which is basically the information I am supposed to extract from
rmformat.  But then the next step for either UFS or PCFS is to fdisk
/dev/rdsk/c1t0d0p0, and I have no p0, only a couple of sX entries,
X=[0..7].
