Netware 6.5 SP4, traditional SYS volume & an NSS Pool with four volumes (VOL1-4).

Today I've gone into ConsoleOne to expand VOL2 (100GB available in pool) and the Media, Devices tab is blank with the message "This device does not appear to have a valid partition table. It must be initialized before it can be used."

This is possibly the first time I've gone to change a Volume since the migration 2 & a half years ago, when I originally allocated space. I've done some searching & found a very old TID (10025907) that has the following "SET IGNORE DISK GEOMETRY=ON must be added to STARTUP.NCF", is this all I need to do, or is my problem something more serious?
