5.5.5 Editing and Creating Additional Host IDs
(Optional)
All RAID arrays are preconfigured when they arrive from the factory.
Default host channel IDs are displayed in
TABLE 5-4
.
The number of host IDs depends on the configuration mode:
■
In point-to-point mode, only one ID should be assigned to each channel.
■
In loop mode, up to 16 IDs can be assigned to each Fibre Channel, not to exceed a
maximum of 32 IDs per array.
Typically host IDs are distributed between the primary and secondary controllers to
load-balance the I/O in the most effective manner for the network.
Each ID number must be a unique number within the host channel. You can:
■
Edit each host ID number to change the target number of each controller host
channel that is seen by the host
■
Add additional host ID numbers for loop configurations
NOTICE: Change made to this setting will NOT take effect until the
controller is RESET. Prior to resetting the controller, operation
may not proceed normally. Do you want to reset the controller now?
