I am having a strange kind of issue.
couple of days before one port lost on san switch and our ESXi stop responding. even we have redundant path and configured fail-over through PowerPath.
so once i fixed the port connection and tried to reboot the host other nodes and this one again stops responding.
Storage is FC /EMC unity/ ESX6.5
LOG
vcenter-server: Issue detected on <ESXi Name> in datacenter : PowerPath:Path vmhba2:C0:T3:L41 to<serial number of stroage array> is dead.
I can also see that even after my fix ( ilo is showing the connection is ok ) but esxi was still complaining about lost datastore.
now I have powered off my esxi server to keep cluster stable.
if i power-up my server i might again have issues with my whole cluster. So in this problem how i fix it.
How i can make sure that if i powered-up the issue will not come back.
should i need to reboot everything or any other suggestion. thanks
