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

May I ask you to provide us with the screenshots that`d illustrated that there is no MPIO, as you have mentioned?

Also, can you confirm that you have added all paths to target in iSCSI initiator?

Thank you

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.
