H.5 Configuring the FC Disk Channels
You can change two configuration options for each FC disk channel:
• Link speed: This is the maximum speed the EF2800 will attempt to
negotiate. You can set the speed to: 1 GB/second or 2 GB/second.
The Link Speed setting is set on the Ops Panel switches (see section
1.2.2.1 on page 6 .
• Initiator ID assigned to each channel: The EF2800 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 EF2800. If the EF2800 cannot get the specified Loop
ID during the loop initialization process, it will try to get a soft
address.
