Hi,
I am getting a two C and D drive for single server in NPM monitor. How to resolve and what is the issue?
If this is a virtual machine, it could be that the machine was reconfigured, leading to the drives having new identifiers within the OS, which then leads to NPM picking them up as new. This isn't automatically resoulved during rediscoveries/polling, so you'll need to find out which drives are the 'dead' ones, but looking at the polling data. The ones which have no data can be deleted by going to 'list resources' for the node in question, selecting the erroneous drives, and then clicking the delete button.
That will resolve your problem.
