The next step is to edit Host ID/WWN Mask. Move cursor bar
through the menu items and press ENTER on "Host ID/WWN Mask."
LUN Mask (ID Range) Configuration:
Ranges can be established by combining a basis ID with a mask
similar to the way routing table entries are set up on a LAN/WAN. If
the port name ID "AND'ed" with the mask equals the basis ID
AND'ed with the mask, then the port name ID is considered to fall
within the range. If a default value "0xFFFFFFFFFFFFFF" is selected,
then the port name ID must match the basis ID for the port name to be
considered to fall within the range. "0x" means that all values are
presented in hexadecimal. If, for instance, a value
"0xFFFFFFFFFFFFFC" is selected, and the basic ID is
"0x11111111111111," port name IDs ranging from "0x….1110" to
"0x….1113" will fall in the ID range.
Usually, a host HBA's port name can be used as the basic ID. If the
host adapter's port name is used as the basic ID and the default mask
value, "0xFFFFFFFFFFFFFF," is applied, the host will fall exactly
within the ID range for the port name ID AND'ed with mask equals
the basic ID AND'ed with mask.
Filter Type: Include or Exclude
Filter entry can serve both ends: to include or exclude certain adapters
from data access.
