When you migrate a virtual machine with I/O filters, specific considerations apply.
If you use Storage vMotion to migrate a virtual machine with I/O filters, a destination datastore must be connected to hosts with compatible I/O filters installed.
- Common Rules for the I/O filters
- Rule Set 1 for the VMFS datastore. Because Storage Policy Based Management does not offer an explicit VMFS policy, the rule set must include tag-based rules for the VMFS datastore.
- Rule Set 2 for the Virtual Volumes datastore
When Storage vMotion migrates the virtual machine, the correct rule set that corresponds to the target datastore is selected. The I/O filter rules remain unchanged.
If you do not specify rules for datastores and define only Common Rules for the I/O filters, the system applies default storage policies for the datastores.
