Replacing root disks in HPUX 11.23

[Heinrich Geiger]

Hello together,

I have a Integrity server with 2x 73GB internal hard drivers. This drives are connected to the internal RAID-Controller.

ioscan saying:
0/2/1/0/4/0 ext_bus PCI-X SmartArray 6402 RAID Controller
0/2/1/0/4/0.0 target
0/2/1/0/4/0.0.0 disk HP LOGICAL VOLUME

So, now I would like to replace this disks with bigger disks (146GB).

How can I do this?
What steps are to do?

Thanks & Regards,
Heinrich Geiger

Take the Ignite backup, replace the disk and restore it from Ignite..

Ignite or if you are using 11.23 or 11.31 you can use DRD.

First, backup to tape (using ignite)
#make_tape_recovery -AI
than, halt your server, unplug old disk and plug your new disk, Install using ignite

It's always good to have a backup ;-)

I would try to swap 1 disk at a time, the logical drive will remain, but you have more space left to extend this drive or create another logical drive.

If you extend the drive (man saconfig/sautil), use vgmodify to adjust the LVM settings.
