I have a configuration mistake in my dx80 and the system is already in production. I have to set "iSCSI Discovery Reply Mode" at "Host Response" configuration to "All - Reply All Ports (Default)". Is it safe to change this value in operation, or do I really need a downtime? Some practice experience would be great.
There are 11 XenServer attached to it with multipathing. 4 of 4 paths active but just 1 iSCSI session (thats the reason why I need to change this setting).
