Disk Path Manager
Disk Path Manager shows you the physical disks seen by ports managed by SANmelody software. By default, information for Fibre Channel ports are displayed, but you can also display information for iSCSI ports by selecting Show All Ports from the Initiator Ports context menu. All information displayed in Disk Path Manager is in the context of disks and ports.
To open the Help for this snap-in, select the snap-in in the console tree and click the Help button on the toolbar.
