Hi team
I am having 17 host Synergy 660 G10 HPE and all running with Esxi 6.5 U3 15256549 and have the same driver.
Last day, when I shutdown one lane of SAN Switch to test redundancy of SAN Switch, one path SAN of 7/17 host was offline.
But when I powered on SAN Switch, one path SAN of host was not online as below:
All Lun of Host only saw one path as below:
I had to reboot host to fix issue. After host was rebooted, all Lun saw 2 path online.
All lun was configed to use Path selection policy: Most recently used (Vmware) and Storage Array Type policy: VMW_SATP_ALUA.
I use storage Hitachi VSP, All san switch are Cisco MDS9148s.
Please check for me why only 7/17 host had issue and how to fix this issue? This issue happened because of OS or driver of host? I had opened case with HPE but they want me to open case with Vmware to check this issue together.
Thank you!
