A system for monitoring virtual machines includes a master host and a slave host. The slave host includes a primary virtual machine and a secondary virtual machine. The slave host is configured to identify a failure that impacts an ability of at least one of the primary virtual machine and the secondary virtual machine to provide service. If the failure is a Permanent Device Loss failure, the slave host is configured to terminate each impacted virtual machine. If the failure is an All Paths Down failure, the master host is configured to apply one of the following: a first remedy if the primary virtual machine is impacted and the secondary virtual machine is not impacted; a second remedy if the secondary virtual machine is impacted and the primary virtual machine is not impacted; or a third remedy if both the primary virtual machine and the secondary virtual machine are impacted. |
