I am looking for step by step to create a mirror to root drive.

I have 2 x 146GB internal drive. the entire vg00 is create on /dev/disk/disk4_p2, and I need to create a mirro of the root on /dev/rdisk/disk3_p2.

Could sombody please provide detail steps on how to do that? This is a hpux11iv3 server.

Thanks!

Hi Hanry,

down load the manual "When Good Disks Go Bad"

This has all the informtaion in it and is an awesome reference guide.

There also is a document out there called "How to mirror a boot disk" but I cant find the link for it at this time. I will keep looking.

If you want to mirror the root disk, you can follow the below procedure.

create the partition description file

#vi /tmp/ptf

3
EFI 500MB
HPUX 100%
HPSP 400MB

partition the disk using, #idisk -f /tmp/ptf -w <ur new disk>

once partition is created you can create the device files for the same.

insf -e -H <hw path of the disk>

create the PV as a bootable one using the following:

pvcreate -B rawdiskname

vgextend /dev/vg00 /diskname-block

using the mkboot command to copy the utilities,

mkboot –e –l <raw whole disk>

update the autofile

echo “boot vmunix” > ./AUTO

efi_cp -d /dev/rdsk/c2t1d0s1 ./AUTO /efi/hpux/auto ---> copy from ./AUTO to new EFI partition

lvextend all the vg00 lv's to the new disks

lvextend -m 1 /dev/vg00/lvol1 /dev/disk/diskname

update the boot data, root volume group

lvlnboot -R /dev/vg00

verify with,

lvlnboot –v

set the new disk as alternate boot path

setboot –a <hw path for ex 0/1/1/0.1.0>

add the new disk to the /stand/bootconf file for SDUX updates

vi /stand/bootconf

1 /dev/disk/diskname

I hope this works well.

Regards,
