I have an IBM DS3500 ISCSI 1GB/s with 7.84.44.00 firmware, connected to two ESX version is 4.1U3 path11 buil 988178
Do you know about compatibility of multipathing ALUA with ESX 4.1U3?
Look this link:http://www.ibm.com/developerworks/forums/thread.jspa?messageID=14900863&tstart=0
an ALUA-supported multipath driver is installed in the host
How can I check if my ESX host there is an ALUA-supported multipath driver?
