TWO DEVICE FILE FOR ROOT VOLUME GROUP

While taking ignite backup, I got the following error:

While trouble shooting, I found that root disk has two set of device files, disk10 and disk11. But system shows only disk11, moreover disk10 does have disk10_p2 partition. Please find different command outputs which will help you to identify the issue.

I want to remove disk10 entries from the IO_TREE and keep only disk11 entries. Please help.

There is something really strange ...

Normal boot disk layout is partition 1 for EFI, partition 2 for HP-UX and partition 3 as a service partition for EFI utilities.

On your system partition 2 is missing, partition 3 is HP-UX.

And you have 2 disk device files.

Can you chaeck if the presentation mode on the disk array is set to HP-UX (not anything like standard or windows)?
