5.9.2 Mapping a general spare
You will notice in Figure 5-35 that the general spare does not have a LUN
number assigned to it. To get a new LUN number for this drive, you select the
drive and click the Properties button.
The Drive Properties window appears; select the Change FC button. A dialog
box opens, as shown in Figure 5-36.
Figure 5-36 Mapping a general spare
The Original Mapping box will indicate that no LUN was assigned previously.
Click the Get New Mapping button, and the next sequential available LUN
number will appear in the New Mapping box. Click OK. The drive will now appear
in the Physical Drive window of the Control Center.
This can also be used to modify the LUN number on an existing mapped drive,
as well as remove the LUN number to ‘unmap’ a drive and create a general
spare.
It is not necessary to map a general spare. A general spare can be used to
creating a composite, mirror, or copy drive. Mapping a general spare will create a
drive that has a LUN number that can then be used by the host.
5.9.3 Removing a mirror containing composite drive
The mirror in this case was made from logical drives on their own. Once the
mirror is removed, the composite drives that made up the mirror will return to the
Composite Drive window as viewed from the Control Center.
