exchange 2010 log drive switch

Hi all,

Exchange 2010 SP1

We have one DAG with 4 MBX servers.  One DAG member with passive copy databases
has very low disk space in the log drive E.  Now, we added another disk with more space
for the log drive E.  I need to switch this DAG member (passive copy databases) to use this
new disk for the log.

What's proper way to change this server to use the new disk for the log drive?

Thank you very much!
