Hello, Using FILEIO as the backend and VMware ESXi as the client we often see: dmesg root@linuxstore-4:~# dmesg |tail [155728.026328] rport-0:0-15: blocked FC remote port time out: removing rport [155847.025545] MODE SENSE: unimplemented page/subpage: 0x1c/0x02 [155847.028062] MODE SENSE: unimplemented page/subpage: 0x1c/0x02 [157374.686113] MODE SENSE: unimplemented page/subpage: 0x1c/0x02 [157374.688565] MODE SENSE: unimplemented page/subpage: 0x1c/0x02 [157921.909960] MODE SENSE: unimplemented page/subpage: 0x1c/0x02 [157921.912399] MODE SENSE: unimplemented page/subpage: 0x1c/0x02 [158722.277771] rport-0:0-24: blocked FC remote port time out: removing rport [160465.594136] MODE SENSE: unimplemented page/subpage: 0x1c/0x02 [160465.596641] MODE SENSE: unimplemented page/subpage: 0x1c/0x02 This is on Ubuntu 13.10. The question is what it means and if it's anything we need to worry about? After digging a bit in the sources it looks like some commands which are not implemented but it's hard for me to say about their importance.
