IBM SAN Error Message
Not sure if this is more appropriate here or under "Storage" but here it is: We have a 4 node NW 6.5/SP7 NCS cluster on an IBM DS4400 Storage Server. We have been seeing this message for some time: "Logical Drive not on preferred path due to ADT/RDAC failover". Any other IBM SAN users out there ever see this? IBM is telling us it's because we do not have multipathing configured properly. Strange that it's worked fine for over 5 years with no errors and now they say we have a config issue. Thanks.
