How to recovery of partition efi file

[vasanth_2]

Hey all
I've done the following experiment
I created efi partition on one spare disk in an ia64 hp server rx3600.So I "ioscan" it and there is the following output:
/dev/dsk/cxtxd0 /dev/dsk/cxtxd0s1 /dev/dsk/cxtxd0s2 /dev/dsk/cxtxd0s3
Now I want to recovery it to the original status it means no eif partition just one /dev/dsk/cxtxd0 and /dev/rdsk/cxtxd0 and not followed by /dev/dsk/cxtxd0sx.
So can you tell me how to do it? Urgent!!!!!!!

This posting looks almost identical to this one from 2006. http://forums.itrc.hp.com/service/forums/questionanswer.do?admit=&threadId=1072177

What OS do you have on this server and what command that you used to create the EFI partition? It may be used to delete it as well.

Hi TTR,

Already i have given these command . But its not working. still it showing the partitons.

[TTr · Accepted solution]

Perhaps the partitions are deleted but the device files are still there. Use rmsf /dev/dsk/cXtYd0 and rmsf /dev/dsk/cXtYd0s1|2|3 to delete them and then recreate the "d0" device file with insf -e -H .

Now its showing like below output.

Class I H/W Path Driver S/W State H/W Type Description
==============================================================================
disk 8 0/4/1/0.0.0.6.0 sdisk CLAIMED DEVICE HP IR Volume
/dev/dsk/c3t6d0 /dev/dsk/c3t6d0s2 /dev/rdsk/c3t6d0 /dev/rdsk/c3t6d0s2
/dev/dsk/c3t6d0s1 /dev/dsk/c3t6d0s3 /dev/rdsk/c3t6d0s1 /dev/rdsk/c3t6d0s3


I need to reovery to this orginal status.

disk 8 0/4/1/0.0.0.6.0 sdisk CLAIMED DEVICE HP IR Volume
/dev/dsk/c3t6d0 /dev/rdsk/c3t6d0

[TTr]

Isn't the c3t6d0 the boot disk? What does "lvlnboot -v" show?
