Solutiona. Create a partition description file. For example:
# vi /tmp/pdf
In this example the partition description file contains:
3
EFI 500MB
HPUX 100%
HPSP 400MB
b. Partition the disk using idisk and the partition description file created in step 1a:
# idisk -f /tmp/pdf -w /dev/rdsk/c2t1d0
page 26 of attached.

Re: EFI partitions removed by mistake.
System still up? Check with idisk if the partitions are still valid.
Hope this helps!

Torsten.

Re: EFI partitions removed by mistake.
With that in mind, the bootable DVD and the EFI are both used for bringin up the box.
Restoring from an ignite image takes no time at all and may be the easiest solution.
Here is the latest doc on HP's System Reocvery.

Re: EFI partitions removed by mistake.
The man page says about -R:
==> The -w option must be specified for information to be written to the disk.
but the examples on the same page say
==> Destroy all partition information on the disk:
idisk -R /dev/rdsk/c1t4d0
But it also says
==> Restore partition information from either a good primary or alternate header or table to the header or table that is bad:
idisk -w -r /dev/rdsk/c1t4d0
http://docs.hp.com/en/B2355-60130/idisk.1M.html
Maybe its time to look for your backup now ... just to be safe before proceeding.
Hope this helps!
Regards
Torsten.

Re: EFI partitions removed by mistake.
Hi
Can you explain how the EFI was destroyed? I have a professional curiousity in any thing that will knock down a box.
