HI,
Diskpart didnt work for me and I dont know why. I have the free space at
the end of the drive I wish to extend and I powered off one node then took
the Group I wanted to work with offline and brought only its disk back online
and no luck. What am I missing? I have three disk groups on the cluster.
Quorum, SQL Virtual Server, and a 3rd Party App. Each have their own IP's,
Names and Drives. I am trying to extend the drive on the 3rd party app
group. I even ran handles.exe and saw no open handles. I am using HP
hardware. Do I need to disable any services? I have multipath 2.0, HP diag
stuff and cluster service. I would assume that I shouldnt stop the cluster
service. I tried stopping all the HP and compaq services and it still didnt
work. Multipath was stopped as well and no go. I am desperate now. Please
does anyone have any advice?
Thanks
