savevg and restvg

[hoang06]

Hi,
I've tried to copy a user's vg, from one server to another. For example, server 1 has vg00 which comprise of hdisk2 and hdisk3. On server 2, I have 4 disks which has the same amount of space for vg00.
On server 1 I use this command: savevg -i vg00.
When I want to restore it on server 2, where vg00 has not been created, I use this command: restvg -f/dev/rmt0 hdsik3 hdisk4 hdisk4 hdsik5.

I got this error message:
restore: 0511-158 cannot open /dev/rmt0. The device is not ready for operation.

I just restore rootvg on disk1 and 2, it worked fine.
Does anybody have any ideas what when wrong?
Do I have to play with /tmp/vgdata/vg00/vg00.data on the tape?

Thanks

No, it's a problem with the tape drive. Does it show in 'lscfg'??

Try diag to test the drive.

Yes it does.
On server 1 the block size of the tape drive is 1024, on server 2 is 0. I changed it to 1024 and rebooted the server.
I tried restvg and through smit and I get:
0512-025 restvg: The image data file does not exist.

I though /tmp/vgdata/vg00/vg00.data was copied with the tape when I issued the command savevg -i.

thks

Are the two servers on the same network? What about doing a copy using NFS from the old server to the new server? Be sure to use the -p parameter for the cp command. If you have a slow network, it may take a while, but it works fairly easily.
