Firstly Check true multipath
status (XenCentre can report it incorrectly). You should see two paths in Round
Robin for each Storage Repository
Multipath –ll
If this reports two per SR as
expected then we simply need to tell XenCentre to update/refresh its view this
is accomplished by running the below command, give it a minute and XenCentre
should then report the correct number of connections.
/opt/xensource/sm/mpathcount.py
If the multipath –ll doesn’t
report as expected the quickest and simplest way to resolve is to put the host
in maintenance mode, disable multipathing wait 2 minutes and then re-enable
multipathing. Wait a couple of minutes and then check the multipath status as
per above. Once happy you can leave maintenance mode. This seems to sort
the problem 9/10 times. Failing that if you may need to restart the
open-iscsi service, command below;
Service open-iscsi restart
