External RAID Controller Operation Overview
4-64 GAM Client v3.00 and WSAM User’s Manual
Enable All Hosts allows a logical drive LUN assignment that is enabled for
all hosts on the loop. This allows all hosts on the loop access to the logical
drive through the LUN without having to redefine the mapping as new hosts
are added to the loop. Enable All Hosts mapping is the default mapping for
all new configurations and old configurations that are converted to new
configurations.
☛ Note
Enable All Hosts can generate an error if another
logical drive is sharing a LUN with the logical drive
being enabled and hosts have been assigned to the
logical drive. The operation is not allowed.
Host to Logical Drive Mapping
Host to logical drive mapping associates hosts on the fibre channel loop to
logical drives. The hosts are displayed on the left side of the list including
the state of the host and the host’s identity, either WWN or IP address.
☛ Note
The host identity is the WWN (World Wide Name) of
a Host Bus Adapter (HBA) of a server (computer on
the IP network) on the fibre channel loop. An attempt
is made to find the server. Servers with multiple
HBAs have an ordinal number in parentheses after the
name/IP address identifying the HBA. A right mouse
click on the server will toggle through the name/IP
address and WWN of the HBA.
The host states are defined as:
• Not Connected—This is a valid host not logged on to the loop.
• Connected—The host is logged on to the fibre channel loop. The host
cannot be found on the IP network. The WWN of the host HBA is
displayed on the network.
• Found—The lost is logged on and found. The IP address or host name
is displayed. A server may have more than one.
Available hosts on the network are determined from the following:
