Use the following recommendations and rules when configuring storage operations or when selecting the storage location for a policy:

• It is not recommended to allow Capacity Managed images and Fixed retention images to be written to the same volume in a disk storage unit. The volume may fill with fixed-retention images and not allow the space management logic to operate as expected.

• All SLPs that write to a volume in a disk storage unit should write images of the same retention type: Fixed or Capacity Managed.

• Do not write images both to a volume in a disk storage unit within a storage lifecycle policy and to the same volume (by the storage unit) directly from a policy.

• Mark all disk storage units that are used with SLPs as On demand only.

• Check any storage unit groups to make sure that fixed and capacity-managed images cannot be written to the same volume in a disk storage unit.
