12.3 Configuration
Listed below are steps necessary for configuring a redundant
controller system:
1. Configure, separately, each controller in "Autoconfig" mode.
When two controllers are powered on later, firmware will
determine which is the Primary.
2. If SCSI channel 0 is used as the communications channel,
firmware will display channel status as "RCCOM (Redundant
Controller Communications)." This channel will then be excluded
from the use of host/drive connection.
3. When powering on both controllers together, LCD will display
"RC connecting." After the controller negotiation is completed, the
communications between controllers will be established.
4. Configure your SCSI/Fibre channels as host or drive. The default
configuration for SCSI channel termination is "enabled." Please
refer to Appendix D of your controller Hardware Manual and
examine whether the termination jumpers on controller backplane
are shunted. If the associated jumpers are shunted, SCSI channels
will be terminated on the controller side no matter firmware setting
is "enabled" or "disabled."
5. Create a "Primary ID" and a "Secondary ID" on every drive
channel.
6. Reset controller for the configuration to take effect.
7. Create Logical drives/logical volumes and assign each logical
unit to the Primary or to the Secondary controller.
8. Proceed with Host LUN mapping. After mapping each logical
unit to a Primary or Secondary ID on host channel(s), the
redundant controller configuration is complete.
