• Initiator ID assigned to each channel : The Galaxy 65 Subsystem assigns each of its FC disk
channels one of the FC loop IDs (initiator IDs). The Initiator ID setting is set via the Disk Array
Administrator. You can change the initiator ID assigned to each channel. You may need to do this if
the default ID, 125, conflicts with an EMP ID. You have two options:
– SOFT: Use this setting if you do not care whether the channel’s initiator ID changes when you
power down and power up. This setting lets the FC loop initialization process determine the
initiator ID.
– Any number between 0 and 125: Select a specific number if you want the initiator ID to stay the
same after you power down and power up. The Disk Array Administrator software cannot tell you
which IDs are available. To be sure that you have successfully assigned the ID you want, check
the ID after you restart the Galaxy 65 Subsystem. If the Galaxy 65 Subsystem cannot get the
specified Loop ID during the loop initialization process, it will try to get a soft address.
To configure the FC disk channels:
1 From the System Menu, select Configuration Menu and press Enter .
The Configuration Menu displays.
2 Select Channel Configuration and press Enter .
The Select Disk Channel screen displays.
