connection, host resets, I/O errors eventually (DRBD, but not only)

How can I list logged in nodes?

Hi, is there a way using iscsiadm to list only nodes which are currently logged in? I find that running "iscsiadm -m node" always lists discovered nodes, but can't find a way to list only those which are logged in and therefore available. --~--~-~--~~~---~--~~ You

I'm still getting the hang of iSCSI and multipath, so bear with me if this is a FAQ that I've missed... I have a host attaching to an MD3000i via iSCSI/dm-multipath that is working but showing a lot of the following errors in syslog: multipathd: sdc: readsector0 checker reports path is down M
