can some one help out fast? vgimport problem

Prashant Zanwar_4 — Tue, 23 Nov 2004 09:36:01 GMT

hi,

I have done a vgexport using

-p -m and -f option. Created outfile and mapfile.
When I am trying doing vgimport at other side,

vgimport -p -m -f vg_name

It says is not a block special device.

I am trying to do with -s option which is stuck at beginning vgimport...

Pls help
Thnx
Prashant

I believe that, in order to use the -s option on import, you would have had to use it on the export as well. You'll have to redo the export or manually identify the volumes.

Hi Prashant,

You probably need to map the c values between the two systems. They're probably not the same.
For instance it may be c3 on the exporting system but it's c2 on the importing. Once you have them mapped then just edit the infile.
Option #2 would be to rerun the export using
vgexport -m mapfile -psv vg_name
Then the import will search for the VGs by VGID & no editing would be required.
You can't use "s" on the import unless it was used in the export.

HTH,
Jeff

I have done it with -s option and then copied mapfile to dest host. But this is the just stuck at the beginning of vgimport..

Thnx

Well - if there's a lot of VGs and/or a lot of disks/paths then the -s can take quite some time.
Let it run.....

I do mine like this:

vgexport -v -p -s -m /tmp/vg52.map /dev/vg52

mkdir /dev/vg52
mknod /dev/vg52/group c 64 0x340000

vgimport -v -s -m /tmp/vg52.map /dev/vg52

Hi Prashant,

Looks like you are not seeing all the disks on the other side. Try 'ioscan -fnC disk' on both the servers and compare them. If these are on EMC or XP, you have tools like 'inq', 'xpinfo', that can help you quickly identify the devices.

This problem has been taken care. I had to map the emc disks on the other side and create a infile to import. This has sorted problem.

Thanks
Prashant
