I'm pretty sure your HP CE knows what to do ...


However, see

Re: Primary root disk replacement on 11.11

if you have a mirror root disk ,you r insured to not lost data. If you have a ignite backup you do not have to worry about OS data.

Hi all,
Thank you for your quick reply.

Re: Primary root disk replacement on 11.11

Normally document would say you that pvcreate -B is not required. But in practcally I wont say it works, and I never did it also. I prefer to do manual mirror only.

You may get message that that pv is already recorded in lvmtab.

pvcreate -B creates area on disk for a LIF volume, boot utilities, and a BDRA.

Here vgcfgrestore will do restoring of LVM information,and bootprogram by mkboot command.

But I am not sure that vgcfgrestore does it that restoring BDRA also.
