LUN Mapping Overview
External RAID Controller (Firmware 5.x and below) LUN Mapping allows
logical drives (or system drives) to be made available or unavailable on one
or more host ports. The mapping is performed by assigning Logical Unit
Numbers (LUNs) to logical drives. The LUN assignments are per host port
and are independent of the assignments on other host ports. Logical drives
may be assigned only one LUN per host port.
By not assigning a LUN to a logical drive on a particular host port, that
logical drive is made inaccessible to that host port.
LUN Mapping in Global Array Manager (FW 5.x or below)
For External RAID Controllers using Firmware 5.x or below, Global Array
Manager implements LUN Mapping by allowing the user to map Logical
Unit Numbers (LUNs) to specific controller/port combinations.
After configuring the desired number of logical drives on the Mylex External
RAID Controller, click the LUN Mapping tab in Manual Configuration
(Figure 4-49). (The Controller-Port columns are shown or not shown
depending on the current controller configuration of host ports and duplex
controllers.) By default these logical drives are made available to all existing
host ports in the configuration. LUNs are assigned automatically in
sequential order for each port.
