I think it can be booted from CD.

Is there any instruction how to do that? What are the consequences?

I suppose you are talking about booting from Recovery media, Yes its possible to repair a non bootable system using recovery media. But if there are is a major unrecoverable file system corruption in root vg then the options left are to restore from ignite-UX backup or cold installation from ignite or CD. 

Note: Recovery media is used to recover the bootlif/os partitions.

Instructions to boot from Recovery media: 

1. Boot from the Install/Support Media. Boot from the path of the CD media and do NOT interact with ISL. 

You will get a menu with the following options: 
Install HP-UX          

Run a recovery shell          

Advanced Options 

2. Select "Run a Recovery Shell" from the menu. 
3. Choose the appropriate options to start reparing the boot disk.

Dear Mr. Pradeep,

Thank you for the informative reply.

Considering the options you posted here I think it will be better to restore it from the ignite – UX backup.

Is there any place that I can find the entire procedure for it?

Best regards,

Yali
