Hi,

you can disable at the Storage by using: setsys HostDIF no

Or on the OS Side example for ESX and qlogic:

esxcli system module parameters set -p ql2xt10difvendor=0 -m qlnativefc

thank very much for you answer cali,

In my case i have disable this opcion in our 3par

System parameters from configured settings

------Parameter------ --Value---
RawSpaceAlertFC : 0
RawSpaceAlertNL : 0
RawSpaceAlertSSD : 0
RemoteSyslog : 0
RemoteSyslogHost : 0.0.0.0
SparingAlgorithm : Default
EventLogSize : 3M
VVRetentionTimeMax : 336 Hours
UpgradeNote :

To do an online migration, is it enough to have this parameter disabled at the Storage level? or do you also have to disable it at the OS level (Redhat) like the example you show me with ESXi?
