How BMR processes disk classes with prepare-to-restore options

Table: Actions for system disks describes the actions that BMR performs for system disks and any action you should perform.

Table: Actions for nonsystem disks describes the actions that BMR performs for nonsystem disks and any action you should perform.

Note the following about the restore options columns of the tables:

System only is the Restore system disks/volumes only option for prepare to restore
Import is the Make available volumes on non-restored disks after the system is restored option for prepare to restore

To avoid conflicts with other cluster nodes that may use surviving shared disks during a restore, shared disks should remain restricted or be unmapped or remapped to alternate, non-shared restorable locations. Shared disks should only be unrestricted and restored in-place if other cluster nodes are do not hold the share actively during the restore.

Table: Actions for system disks

Restore options	Action
System only = true and import = true	Restore
System only = true and import = false	Restore
System only = false and import = true	Restore
System only = false and import = false	Restore
System only = true and import = true	Restore

Table: Actions for nonsystem disks

Restore options	Restorable	Nonrestorable	Shared	Missing	New
System only = true and import = true	Import	Import	No action	Mark the restricted disk, remap to a restorable disk, or remove the disk from the restore configuration	Not imported
System only = true and import = false	No action	No action	No action	No action	No action
System only = false and import = true	Restore	Import	No action	Mark the restricted disk, remap to a restorable disk, or remove the disk from the restore configuration	Not imported
System only = false and import = false	Restore	Remove the disk from the restore configuration or mark the disk restricted	No action	Mark the restricted disk, remap to a restorable disk, or remove the disk from the restore configuration	No action
System only = true and import = true	Import	Import	No action	Mark the restricted disk, remap to a restorable disk, or remove the disk from the restore configuration	Not imported
