We have cluster of vmware esxi 5.5 hosts and they are connected to HP LeftHand storages.
LeftHand storages are planned to be updated with the latest version.
Because there is a possibility storage update to failed, and Lun presented from the storages to ESXi host to appear as not available, I was wondering is there anything(any advanced settings in esxi 5.5) that I can configure in esxi 5.5 so I can protect VMs in case of this scenario(PDL and APD). From v6 and above it is easy, we have a VMCP module and settings for PDL and APD down scenario, but what about version of esxi 5.5.
Could you recommend me something, or should I stay with the default settings of esxi5.5 hosts.
