Zerto Error " The Microsoft default SAN policy might cause VM (VM name) volumes to become offli
This alert is triggered by having Windows hosts with multiple drives. The alert mechanism does not check your actual SAN policy but instead just checks your VMs operating system and if it is certain versions of Windows it will throw the alert. This alert is to bring to your attention to the fact that VMs on certain version of Windows may encounter issues with offline drives when they are recovered, due to the default SAN policy.
Solution:
The resolution requires setting the diskpart policy to "OnlineAll" using the following steps:
1) Open the command prompt on the relevant vm. 2) Launch "diskpart" 3) Type "san" to confirm the server is set to "Offline Shared" 4) Typed "san policy=OnlineAll"
