Replacing/migrating 2x LOCK/Data Disks in a shared VG (2-node cluster)

[omegax]

Good day All,

I have a 2 node cluster with 2x LOCK DISKs and 1x shared VG.
The LOCK DISKs are also data disks in the shared VG.
Let's say the shared VG has 10 disks in it (2x being the lock disks) and I need to migrate the shared VG to another new set of 10 disks (or possibly 5 larger disks). I can easily migrate the single LV in the shared VG to the new disks using lvm
mirroring, BUT how do I "migrate" the lock disks function to 2 disks in the new set of disks?

I would also appreciate the order of steps (because I suspect that may be important)

Most of the documentation for ServiceGuard I have seen only seem to discuss how to replace the LOCK disks when they are in a separate dedicated LOCK VG of their own.

Thanks.
