Administrator Guide

• Whether to delete the configuration for a removed I/O card
The wizard guides you through the following actions:
• Associating I/O cards with existing port configurations
• Indicating which I/O cards are new hardware
• Deleting configurations for I/O cards that have been removed
Before using the wizard, you should be aware of the following:
• Changes should be performed by a certified installer or with the assistance of technical support.
• At least one back-end port must remain in its original location.
• A controller restart is required to implement changes.
• Do not rebalance any ports until controllershave been replaced and all hardware configuration changes are complete.
Plan a Hardware Change
Upon boot, the Storage Center searches back-end targets for the configuration. Because a controller cannot boot without configuration
information, back-end access must be maintained during the controller replacement procedure. This can be done in two ways:
About this task
• Keep at least one common back-end slot/port defined and connected in the same manner on the new hardware configuration as it
was on the old hardware configuration.
• Connect the back-end to a port that is undefined on the new hardware configuration. Storage Center is able to detect iSCSI targets
and acquire the boot configuration from the drives even though the slot/port is marked as undefined.
When the appropriate back-end slot/port is identified, record this information on the Port Usage Work Sheet and continue the upgrade
process.
Change the Hardware
Changing hardware follows these general tasks. Refer to upgrade documentation for the specific change for more detailed instructions.
Steps
1. Power down and unplug the controller. This reduces downtime by facilitating re-cabling. In a dual-controller Storage Center, the
second controller takes on all functions of the Storage Center, preventing a system outage.
2. Record/tag the cabling for the affected card.
3. Disconnect the cables on the I/O card.
4. Replace, move, or remove the I/O cards and reconnect as recorded on the Port Usage Work Sheet.
5. Plug in and power on the controller.
Manage I/O Card Changes
After a change to an I/O card in a Storage Center controller, the Configure I/O Card Changes wizard applies old port configurations to the
new or modified ports. Changes can include replacing an I/O card, moving the I/O card to a different PCI slot, and removing an I/O card.
Use the Configure I/O Card Changes wizard to apply existing I/O card port configuration settings to new or modified I/O card ports.
Steps
1. If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2. Click the Hardware tab.
The Hardware view is displayed.
3. In the Hardware navigation pane, select a controller, then click Configure I/O Card Change.
NOTE:
If the controller must be restarted to move configurations to the other controller, the Configure I/O Card
Changes wizard shows the option to restart the controller.
The Configure I/O Card Changes wizard opens.
4. (Optional) Click Restart Controller.
5. Click Next.
6. From the Fibre Channel, iSCSI, or SAS table, identify ports that have been modified.
7. From the Card Location drop-down menu, select a port configuration.
