Infortrend RAID Controller Manual

9-20
Include: If a node's (a workstation or a server) WWN falls in an ID
range specified as "Include," the node will be allowed to access the
storage capacity mapped to the associated LUN. The access mode
can be "read only" or "read/write."
Exclude: If a node's WWN falls in an ID range specified as "Exclude,"
the node will not be allowed to access the storage capacity mapped
with this entry.
Multiple ranges, or filter entries, can be established for a single
channel, target-ID, and LUN combination. Each range can have its
own Exclude/Include attributes. The rules for determining whether a
particular ID is considered as "included" or "excluded" are listed
below:
1. If an ID falls within one or more Include ranges and does not fall
in any Exclude range, then it is included.
2. If an ID falls within ANY Exclude range no matter if it also falls in
another Include range, then it is excluded.
3. If the ID falls in none of the ranges and there is at least one Include
range specified, then the ID should be considered as excluded.
4. If the ID falls in none of the ranges and only Exclude ranges are
specified, then the ID is considered as included.
Access Mode: Read Only or Read/Write
A particular extended LUN map can be setup with an attribute of
"Read Only" in the event that certain hosts may need to read the data
on the media but must not be allowed to change it. In the degenerate
case (range only includes a single ID), different hosts can be mapped
with completely different logical drives/logical volumes/logical
partitions even when they address the same channel, target-ID, and
LUN.
When completed with configuring LUN mask, press [ESC] to map a
logical unit to LUN.
Multiple filter entries can be created for a Host ID/LUN combination,
select the Host LUN again to enter the editing menu.
