11iv3 - creating VGs and using mknod ..minor numbers

i created an vg some time ago on host1  say with minor number 10.

We utilize BCVs mapped on  host2 so we can daily sync with primary hosts (ie host1)  and then  backup the bcvs.

 

I normally export the vg  from host1 and import to  host2.

Does the minor number on the host2 (bcv host) need to match that of host1 when I run the mknod on it host2?

heres my issue.. the minor is already in use on host2

The minor number doesn't need to be same.

Hope this helps!

As Thorsten said, it does not need - but if you keep them your life will be much easier in case of troubleshooting or let's say it's just better style.
