 | EPC_HARDWARE_DEVICE          | This error is encountered when a Virtual Machine’s parallel Port/USB Device is connected to a device can't be accessed on the destination host. | If you're using an image file (ISO, FLP, and so on), ensure that it's accessible from all ESXi servers of the cluster. Store the files on a data store that is shared between all ESXi servers that participate in the vMotion of the virtual machine. Refer to [this KB article](https://knowledge.broadcom.com/external/article/324829/vmotion-fails-with-the-compatibility-err.html) from Broadcom for more information. |
 | EPC_INVALIDVM / EPC_ORPHANVM | This error is encountered when there's an orphaned or Invalid VM in the inventory | Ensure all your Virtual Machines are accessible to the vCenter. Refer to [this KB article](https://knowledge.broadcom.com/external/article/312831/virtual-machines-appear-as-invalid-or-or.html) for more information. |
 | EPC_VMHOSTDRSRULE | This error is encountered when there's a Virtual Machine with Host affinity/anti-affinity DRS rule. | VM shouldn't block VMware vMotion while putting a host into maintenance mode. Set "should rules" for VM-Host affinity. Refer to [this document](/azure/azure-vmware/create-placement-policy#what-is-the-difference-between-the-vm-host-affinity-policy-and-restrict-vm-movement) for more information. |

+| EPC_FTT_ZERO | This error is encountered when a virtual machine has "Failures to Tolerate" as 0 or "No data redundancy" | Follow [this KB article](https://knowledge.broadcom.com/external/article/391522/the-esxi-host-takes-very-long-time-enter.html) to configure FTT as 1 or 2 for the Virtual Machine. |
+| EPC_FTTVIOLATION | This error is encountered when a cluster does not have the minimum number of hosts that the storage policy needs. | Add hosts as needed by the storage policy or change the VM FTT policy to support putting the host into maintenance mode. Refer to [this KB article](https://knowledge.broadcom.com/external/article/326857/vsan-host-fails-to-enter-maintenance-mod.html) to know more about FTT policy. |

These alarms are used by Azure VMware Solution monitoring to trigger the Azure VMware Solution host remediation process.
