Connecting to Your Dual-Controller Storage System

Verifying the Controller Operating Parameters

Refer to the Getting Started RAID Array 3000 Installation Guide to configure
the virtual disks as communications LUNs.
1. Open the StorageWorks Management Utility.
2. Refer to the Getting Started RAID Array 3000 Installation Guide for
instructions describing how to connect the RA3000 to your host system.
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. Click 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.
