Hi Forum,

we are testing Open-E with iSCSI Failover and Multipathing and Citrix XenServer 5.6 FP1.

All is configured like shown in the webinar last week. Only additional iptable rules are set, so disable connections to the physical ip's of the storage server, so only iscsi traffic to the 2 virtual ip's is allowd. The multipath.conf is configured as shown.
All works like a charme with one exception.

The iSCSI multipath connections are not stable at all 3 XenServers. There are often (all 2-4 minutes) alerts, that only 1 path is active.

We use new HP Servers for storage and XenServer with 2x1GBit connection for every machine to 2 HP Switches (2810-24G).

What is the problem? Are there any hints, if we can tweak some more in the multipath.conf ?

tia, Olaf
