Just for those encountering the same problem: When backing up a csv-volume (in my case 3-node HA native-SAN) the process of generating the shadow copies consumes all memory on the addressed current node. That leads to a node restart :( That happens with any backup soft (Veeam, DPM ....) using the MS...

thx to Max! I simply forgot to enable MPIO in
MPIOcpl ->second tab-> add support for iSCSI devices

Anatoly,

yes all paths are connected, e.g. on vs1 connection to itself, to vs2 and to vs3 (firstnode, secondnode and thirdnode). Same on vs2 (connections to vs1 and vs3).
But on vs3 the connections don't show up as mpio paths but as singe scsi (iscsi) volumes, see attached images.

Hi, After setting up a two node cluster (working fine) I added a third node, equally configured, but when I try to mount the ISCSI targets I just see the scsi, not the mpio target. This only happens on the third node (vs3), MPIO is configured here but not visible in the targets, thx for any help, Ralf
