Are you planning to use Veritas Volummanager or HP LVM?

Good Morning Preben,

I am using LVM to control a XIOTech MAGNITUDE.

My issue is the abiltity to failover the Volume Group from my primary server
(topgun L Class) to my secondary server (mig K Class).

I can import, export, activate and deactivate when I buiild the
Volume Group on each individual host. I am aware that I am to build the VG
from only one node. I have removed any trace of the old VG and rebuilt the
VG from topgun and I am not able to bring the VG online on mig. The /dev/volgrpname
on the servers are different. How can I get those to match up?

Does the VG have to be shared via DLM or MCSC? I know from my Solaris Foundation
Suite and VCS test bed that the shared Volume Manager DG's and VG are locked
when one server has control of the shared disks.

Thanks for any insight you might have.

do something like this:

- make shure that both nodes see evry device on the shared disk storage.
You can use 'ioscan' and 'insf' for this.
- Create the VG dir unnder /dev with the same name on both nodes. And create
the group file with the same id on both nodes also.
- Create the volumgroup on one node, with volumes and filesystems.
- Then do an export with the -p and -m options so that you get a map file.
Ftp this file to the other host, end do a import here. Also copy the device
files from /dev/myvg from the first host to the other (tar,ftp or simular
methods).
- Deactivate the VG on the first node and then try activate it on the other.
- Mount the filesystem(s)

Is this the information you are looking for: how to create a VG that can
be activeted one 2 nodes, but only 1 at a time?

Thank you very much for your help.

I neglected to create the map file. Rookie mistake.

I appreciate your help. The cluster is working perfectly now.

If I may be of any assistance in the future, I owe you one.
