I have noticed in the past few months as I've been settling my system in (getting everything configured right and all) that my Synology NAS which is hosting an iSCSI volume randomly appears to "disconnect" from certain hosts. I put that in quotes as the Synology UI still shows the host as connected however the host displays that the SCSI route is dead in the network adapters page and the volume is inactive. Upon attempting to shut down the NAS I am left with powercycling using a hard boot. A power cycle of the NAS is the only option as rebooting the host does not reestablish a connection. Any ideas?
