Rules for Creating IM Volumes and Hot Spare Disks
When creating IM volumes and hot spare disks, the following rules apply:
• All disks that are part of an IM volume or a hot spare for an IM volume must be on the same
SAS controller.
• IM volumes are supported.
• Only two IM volumes (plus a global hot spare) per controller can be created.
• An IM array must have two disks.
• A hot spare disk cannot be created without at least one IM volume already created.
• The utility does not allow adding a hot spare disk type different from disk types in the volume.
• With the AUTO command all drives used are the same type as the first available disk found,
and the size is limited to the size of the smallest disk.
