Setting FC Host Port Link Speed
A host port’s link speed must match the speed of the host (HBA or switch) to which
the port is connected. In a dual-controller system, setting the speed of host port 0 on
one controller also sets the speed of host port 1 on the other controller.
A speed mismatch with the host prevents the host from accessing the storage
system.
To set host port link speed:
1. Select Manage > General Config > Host Port Configuration.
2. For each port that is connected to a host, set the appropriate speed.
The default is 4 Gbit/second.
3. Click Update Host Port Configuration.
Setting FC Host Port Loop IDs
A loop ID identifies a controller to a data host. A loop ID is only a requested value.
The controller requests the specified ID when it arbitrates on the FC loop but the
actual loop IDs assigned to each port during FC loop initialization might differ. This
page shows the requested and current loop ID for each controller.
Generally, you only need to change this setting if you want a controller to be at a
specific address; if your system checks addresses in reverse order (lowest address
first); or if an application requires that specific IDs be assigned to recognize the
system.
To set host port loop IDs:
1. Select Manage > General Config > Host Port Configuration.
2. In the Advanced Options panel, click Change FC Loop ID.
The Requested Loop ID for Host Ports panel displays the currently requested loop
ID and the current loop ID for each controller’s host ports.
3. Select a requested loop ID for each controller:
■ Soft – Select this software addressing setting if it doesn’t matter whether the
controller’s loop ID changes after you power down and power up or after a loop
initialization process (LIP). This setting enables the FC loop initialization process
to determine the loop ID.
