Second Controller Option 5-15

Verifying the Controller Operating Parameters

For optimal dual-controller performance and load balancing, the host ports should be configured as listed below. Verify these parameters from the Controller Properties page:

■Host I/O channel 0 for Controller 1 (top) to Active

■Host I/O channel 1 for Controller 1 to Passive

■Channel 0 Target ID for Controller 1 to 0

■Channel 1 Target ID for Controller 2 to 1

NOTE: It is allowable to configure the host I/O and target IDs as follows:

Controller 1 (top) may be set to “ Passive” while host I/O channel 1 for Controller 1 is set to “ Active” . As long as each host channel value and channel target ID value is unique, the system is correctly configured for Active/Active mode.

1.Select the Environment tab from the Controller Properties window.

2.Ensure the cabinet and UPS settings are set to normal.

3.Select the Cache tab from the Controller Properties window. The SIMMs parameters must be identical between controllers.

4.Select OK. The system is now ready for dual-controller operation. Configuration of additional RAIDsets may now be performed as desired.
