My client has QNAP library that I've used to share 2 iSCSI connections. One to physical machine and the other to virtual machine on top of that machine. One is 4TB (connected to physical machine) and the other one is 1.4TB. Both use Windows 2008 R2 Enterprise
It's 2nd time that iSCSI drive disappeared from virtual machine (and physical host still is connected to the other iSCSI device) and when I used iSCSI initiator to reconnect the drives, they were reconnected but the 1.4TB is treated as RAW and I can't access data. The first time we assumed it was accident but now it's clearly something wrong.
What can be happening and why? How can I fix it?
