When I run vgdisplay I get the following messages:
I have two iSCSI LUN's connected to this host, multipath-tools is NOT installed.
When I run fdisk -l I see several /dev/sdX devices for the same LUN's as follows:
What is going on here? I am having iSCSI problems and was wondering if this is related.
EDIT:
output of iscsiadm -m session shows:
This implies iSCSI is multipathing even though I have not installed or configured multipath-tools??? All I done was enter a single portal IP in the GUI for iSCSI then configured LVM on my 2 LUNS's.

This implies iSCSI is multipathing even though I have not installed or configured multipath-tools??? All I done was enter a single portal IP in the GUI for iSCSI then configured LVM on my 2 LUNS's.
