Note: Mirrored disk note
In a mirrored disk system, the Primary system disk is always installed in the bottom level
of the brackets.
If you are upgrading to a mirrored disk system, position the new hard disk (Mirror
Primary) over the existing hard disk, between the tall brackets. There will be a space
between the hard disks. Refer to
Figure 107 on page 247 .
Note: If you are replacing a failed disk on a mirrored disk system, ensure the new disk is
replaced in the same position in the bracket that the failed disk was removed from.
