Note:
Truthfully if the management network path failure scenario failed over storage providers in a quick and efficient manner, the recommended action would be to force the storage provider failover. However, because of how long the provider failover can take, the best recommendation Pure can make at this time is to not use PowerCLI 12 until a fix for this has been released.
Everpure has identified an issue using PowerCLI versions 12.0 and 12.1 when running commands that query the Storage Providers that are registered in vCenter. For example, cmdlets such as Get-VasaStorageArray and Get-SpbmReplicationGroup will fail with the error "Object reference not set to an instance of an object."
