Persistent DSF is not showing the 3 partitions of the disk.

[Vipin K Gupta]

I am new to HPUX 11.31. I need to mirror a disk. whenever I run pvcreate -B /dev/rdsk/c0t0d0 i gives the error
pvcreate: Couldn't open physical volume "/dev/rdsk/c0t0d0s2":
I/O error

I have run insf to create special file devices.
ioscan -m dsf is not showing the 3 partitions of the disk.

ioscan -funC disk is showing s1,s2 and s3 of the disk.

Kindly resolve.

What is your server model, are you using any hardware raid

be caution! just make it clear which is the original disk and target disk, get a user guide for root disk mirror will do you good!

>>I need to mirror a disk.
you need to mirror root disk or normal VG.

If its normal no need to do a pvcreate -B its for boot disk.

Follow pdf "when good disk go bad"

Hi Gupta

In your case you sould have raid by hardware.


To see the status of the raid do the following command:

sasmgr get_info -D /dev/sasd0 -q raid

If you do not have raid by hardware and you do not have time for downtime. You should do a raid by software.

You need to have the software mirror UX. In 11iv3 it cames by default.

To do the setup follow the directions by the book in " When good discs go bad" ..
