saving volume groups/logical volumes while installing hpux 11.0

[ernest tamura]

We will be installing hpux 11.0 on a k370 server currently running on 10.20. We will do a new install, not an upgrade. Is there a way of saving the volume group and logical volume info and transfer it after 11.0 is installed?

Hi,

I think this thread covers what you are planning:

Hi,

I would have suggested vgexport with mapfile.
But the above thread explains it well.

Use the option from James, that's the way I would have done it.

hi,


A minor addition:
in addition to doing vgexport -p -v -s -m vgname do
ll /dev/*/group >/tmp/groupnames
This will be a reference to run the mknod commands after the O/S is installed.

Hi

RajMan have a good suggestion, but I'll run, for more security "sysinfo -a > server.info" for collect all information about the system.

sysinfo is in attach

HI,
as you are doing new installation, you need to copy the map files created hile exporting volume groups from 10.20 machine to 11.0 machine.

you can also do as below :

1. vgexport -p -v -s -m /tmp/lvm.conf_vg00 /dev/vg00

similarly for all volume groups. Then rcp the map files to any other machine on the network.

2. Now start installing hp-ux 11.0 machine.
3. When it will be over the network, you can copy map files using rcp to 11.0 machine.

It is better to keep a backup of map files on 2 tapes too. Just in case rcp doesn't work or due to some problems.....to be on safer side.

The script that Domenico is great but if don't want everything then take printout of

#vgdisplay -v vg?? (all vg's)
#pvdisplay -v /dev/????? (all pv's)
#cat /etc/fstab
full ioscan
kernal tunable parameters (if you have set any for some software)

Thanks to all that replied to my question. With your help the installation of 11.0 from 10.20 went well and the volume groups transferred over very nicely.
