Mirroring bootable LVM Integrity Linux disk

[Shady Aly]

Dear All

I need to make mirror of bootable Integrity (rx2660)LVM disk on RHEL 4 .....taking care that /dev/sda1 is efi partition,/dev/sda2 is HPSP, /dev/sda3 is an ext3 partition mounted on /efi/boot while /dev/sda4 is used as LVM physical volume from which all vg00 logical volumes are created......the existent sas controller does not support raid...and to replace it with one that support raid data should be destroyed which is not acceptable so i need to make mirror software ... i found many procedures but for hp-ux that uses utilities like idisk,mkboot which are not found in linux....It is not a new installation but the system is production and has no mirror initially... can i use LVM-Mirror for logical volumes(lvconvert -m 1 lvol1)except /boot/efi as it is not lvm-based so i need to use mdadm for it and convert it to software-Raid partition type???????Right......ok if so ....is just mirroring /boot/efi using mdadm and restoring its data is enough to make the second disk bootable..... do i need something like grub-install but you know that EFI uses ELILO so i don't know the corresponding tools....is the second disk bootable

Linux on HP Integrity Servers: A System Administrator's Guide

there could be how to do it.
