HP-UX root disk redundancy

[Ahmed BH]

How can I test/verify the root disk redundancy for HP-UX ??

[Kapil Jha]

a couple of methods...

setboot -a
if you get two entries primary and secondary that means disks are mirrored.

lvdisplay /dev/vg00/lvol*|grep -i mirror

if mirror copies is more than 0, it means its mirrored.

Verify:

# vgdisplay -v vg00

# lvlnboot -v

# setboot

# lvdisplay -v /dev/vg00/...


Test:

boot it!

Precaution!!

Take downtime first ;)

Salam Ahmed,

As stated by above all commands can tell you but If downtime can be arranged, boot from ALT disk.

Hi All,
Its now server and new hp-ux v3.
Its ia64 hp server BL860c server.
It has 2 HDD but not mirrored.
How to mirror 2 HDDs?

Very best would be to create a hardware RAID using the internal LSI chip.
