CVM 4.1 Master Role
Is there any way to choose the next CVM master?
Who would become the next CVM master when vsfcbe4 stops it's CVM SG?
Can I change a config file to make, let us say, sjmemfs07 the next CVM master?
Here is my nidmap as fed from vxclustadm:
# vxclustadm nidmap

- somehow I missed this post...
well there is no file where you can change this information......
Usually the next CVM master is decided with the CVM Node ID, currently in your scenario vfscbe4-prod is master server, if that fails, the next lower CVM Node ID should take over , so I would expect vfscbe1-prod since that has lowest CVM Node ID.
But trust me I have seen inconsistency in this behaviour, I have seen lower LLT node ID taking this behavior... & for sure this is unconfigurable..
