I have ESXi hosts configured to boot from SAN LUN with four active paths and RR PSP. I lost connectivity to the LUN on one of the paths which trigerred a failover, I did not notice any disconnect (ESXi/Datastore) but found that the server stopped writing any logs, what could be the reason for this? I assume that no disconnect was reported because the hypervisor was available from the in-memory file system. What can I do to ensure that the failover of the boot LUN is seamless and the ESXi host is not affected in any way, kindly share any best practices for ESXi.
Thanks in advance.
