[Iscsi Multipath - unknown key DMP]

Thanks for the responses, I have solved this issue by disabling the DMP driver and making a couple of adjustments to the multipath.conf file, the original multipath.conf file was apparently for the eternus DX60 s2 not the s3 version.

[Iscsi Multipath - unknown key DMP]

Hopefully someone can help with this issue.

 

I am trying to configure a shared iscsi storage repository in xenserver 7.1, however when i try via the cli i get 

the target device is a fujitsu eternus DX60 s3 which is on the HCL

 

SR_BACKEND_FAILURE_1

Error reporting error, unknown key DMP failed to activate mapper path,

 

i get the same error via xen center.

 

multipath -ll gives
