We are using Windows Server 2008 R2 iSCSI initiator to connect to an iSCSI target on Sun Storage. On some servers iSCSI target shows connected but no volume appears in Disk Management or disk in Device Manager under Disk Drives. In iSCSI target properties under Devices it shows
Name: Disk -1
Address: Port 1: Bus 0: Target 0: LUN 0
I tried restarting iSCSI service, disconnecting and reconnecting all targets, restarting server without success.
Only action that allows target to show up properly under Disk Management is reinstalling Windows Server.
Any ideas how to troubleshoot this?
