wrong bootdisk

N.Gawlik — Tue, 29 Jul 2008 10:13:02 GMT

Hi,
I have rx2660 und HPUX 11.23.
I have 2 boot Disks ( c7t1d0 with S1,S2,S3 and C7t0d0 with s1,s2,s3).When i make a mirror disk c7t1d0, i did mistake with idisk. I did instead of (idisk -wf /partfile /dev/rdsk/c7t1d0) i did idisk -wf /partfile /dev/rdsk/c1t1d0). Now i have three disks with s Partition and i need only two disks. How can i remove disk c1t1d0 ?

Thnaks
Norbert

Remove partitions with idisk -R, remove special files with rmsf and after that re-create partitions with idisk -wf ....

Hi,
you mean idisk -R /dev/rdsk/c1td0 and afterwards idisk -wf /dev/rdsk/c1t1d0

Hi,

a similar thread follows:

http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1247928

I think it is enough to do the following steps:

pvcreate -f /dev/rdsk/c1t1d0
rmsf -H 0/2/1/0/4/0.1.0
ioscan -fnCdisk
insf -e -H 0/2/1/0/4/0.1.0
ioscan -fnCdisk

HTH.

Hi,
Thanks for your help. I will try it Saturday.

Have a great day !

Re: wrong bootdisk

Deepak Kr — Wed, 30 Jul 2008 10:47:06 GMT

Hi,

Please try this!!
#ioscan -fnkC disk|grep c1t1d0
Note down all device files like

/dev/rdsk/c1t1d0s1
/dev/rdsk/c1t1d0s2
/dev/rdsk/c1t1d0s3

then
run
#idisk -R /dev/rdsk/c1t1d0
Also:
#rmsf /dev/rdsk/c1t1d0s1
#rmsf /dev/rdsk/c1t1d0s2
#rmsf /dev/rdsk/c1t1d0s3

This will remove all newly created device files. Run insf -eC disk to recreate device files for c1t1d0
like

/dev/dsk/c1t1d0
/dev/rdsk/c1t1d0

Hope this will solve your query!!

Cheers!!

IMHO it is better to reverse these steps from post above.
First "rmsf", then "idisk -R ...".
Sometimes you will see problems when trying to remove device files for non-existent devices.

Torsten. — Mon, 04 Aug 2008 07:15:11 GMT

As long as you don't remove the partitions from the disk (idisk -R), your system will again discover them and create device files for them, for example

cxtydzs1, ...s2, ...s3

Fabio Ettore — Mon, 04 Aug 2008 07:42:39 GMT

Hi,

in case you insert again that disk then

idisk -R /dev/rdsk/c1t1d0
pvcreate -f /dev/rdsk/c1t1d0
rmsf -H 0/2/1/0/4/0.1.0
ioscan -fnCdisk
insf -e -H 0/2/1/0/4/0.1.0
ioscan -fnCdisk

and you will have the disk with no partitions.

Best regards,
Fabio

The vgcfgrestore commands depends if you still have a valig config for this disk.

Check with

#vgcfgrestore -n vg02 -l
