Hello, The issue isn't on the Equallogic side, you have "Interface" AKA "IFACE" files, configured in open-iscsi. This does discovery out each defined physical interface and logins as well.
They are located in the open-iscsi directory in the "iface" subdirectory. Logging in to [*iface: libvirt-iface-33d9c275*, target: iqn.2001-05.com.equallogic:4-52aed6-a9251e6aa-f437080d41b5434f-13-1-orig, portal: 192.168.99.55,3260] (multiple) Logging in to *[iface: libvirt-iface-08bf216d*, target: iqn.2001-05.com.equallogic:4-52aed6-a9251e6aa-f437080d41b5434f-13-1-orig, portal: 192.168.99.55,3260] (multiple) If you have multipathd installed it will create an MPIO device allowing you to use multiple paths to reach the SAN, providing better performance and redundancy Typically /dev/mapper/mpath0 /dev/mapper/mpath1, etc... This Tech Report covers how to configure MPIO for RedHat. The basic process is the same for SuSE. Files might be located in different directories. http://en.community.dell.com/cfs-filesystemfile/__key/communityserver-components-postattachments/00-19-86-14-22/TR1062_2D00_LinuxDeploy_2D00_v1-2.pdf Regards, Don On Wed, Oct 22, 2014 at 12:49 PM, Paul Koning <paulkon...@comcast.net> wrote: > > On Oct 22, 2014, at 12:39 PM, Laurent HENRY <laurent.he...@ehess.fr> > wrote: > > > Hello, > > I am noticing a strange behavior with one of my Linux server > (Opensuse > > 13.1 with open-iscsi) > > > > While connecting manually to a iscsi node, my lun is getting mounted > twice. > > This produce troubles on my iscsi disk array, which refuse a multihost > request > > (and i don't want to allow it either). > > > > I think the reason is my disk array (dell equallogic) announce every lun > > twice, i don't know why. > > That would certainly be unexpected, if it is really doing that. > > > > Here is an example: > > > > # iscsiadm -m discovery -t sendtargets -p 192.168.99.55|grep 13.1-orig > > > > 192.168.99.55:3260,1 iqn.2001-05.com.equallogic:4-52aed6-a9251e6aa- > > f437080d41b5434f-13-1-orig > > 192.168.99.55:3260,1 iqn.2001-05.com.equallogic:4-52aed6-a9251e6aa- > > f437080d41b5434f-13-1-orig > > That means either it was announced twice, or it was announced once but the > Linux end turned it into two records.
