migrating parisc to itanium

[Mme Jonnaert]

hi,
we have to migrate our PaRisc server to an Itanium server.
Hpux B.11.11.0303 to hpux B.11.23.0505
the data are on 2 differents san bay and we would like not making a backup/restore
Can we mount the disk from one server to another, executing vgscan on the new server?
The lvm versions are there compatible ?
thanks for your answer

You'll need to run vgexport on the old server and then vgimport on the new one:

vgchange -a n /dev/vg01
vgexport -s -m /tmp/vg01map /dev/vg01

copy the map file to the new server

mkdir /dev/vg01
mknod /dev/vg01/group c64 0x010000
vgimport -s -m /tmp/vg01map /dev/vg01
vgchange -a y /dev/vg01

If you used standard lvol naming conventions, the map file will be unnecessary.

Hi:

For "move" volume groups from one server to another, you 'vgexport' them from the source and 'vgimport' them into the destination server.

See the manpages for 'vgexport' and 'vgimport' for more information.

vgexport/vgimport are your commands to be used.

Depending on your SAN configuration, you may need to do some work there as well. Example, are the new ia64 systems zoned to see the disks on the SAN?

Double check your applications. Most (if not all) are not interchangable between ia64 and PARISC systems.

Can you see both san's from atleast one of the servers?

You will then either have to vgimport or, if you want the data on the other san, use vxdump/vxrestore for every file system:

vxdump -0 -f - -s 1000000 -b 16 /san1/oracle | (cd /oracle ; vxrestore rf -)

Shalom,

With vgexport/vgimport volume groups adn the data on them is a piece of cake.

You just need to provide acess to both servers of the same disk. It must be shared in some way, via scsi or fiber(which works like scsi).

LVM vg's created under HP-UX 11.11 can be imported into 11.23

Hi,

Yes, LVM versions are very same and you can do the vgexport/vgimport as mentioned in earlier posts.

HTH,

It is very easy with vgexport and vgimport.
Pete Randall is an example.
