Creating a New Unit
Whether you create a unit through 3BM or 3DM, when you create a new unit,
you specify the following:
„ Drives to be included in the unit
„
Type of configuration
„ Name for the unit (optional)
„
Stripe size, if appropriate for the RAID level
You can make some changes to the unit later. For details, see “Changing An
Existing Configuration” on page 98.
Drives to be included in the unit
You may include from one to twelve drives in the unit, depending on the
number available. (For information about how many drives to select for a
given RAID level, see Table 2 on page 12.)
You may only select available drives that are not currently part of a unit. If
you want to use drives that are currently part of a different unit, you must
delete that unit, first, to make the drives available. (For details, see “Deleting
a Unit” on page 103.) If drives are listed under “Incomplete Drives and
Others,” they must be deleted before they can be used.
If you want to add drives to be used in the unit, see “Adding a Drive through
3DM” on page 110.
