Managing I/O Card Changes
The Congure I/O Card Changes wizard simplies the task of moving, replacing, upgrading, or repurposing I/O cards in Storage Center
controllers. The wizard is used to congure I/O card hardware changes on a per-port basis after physical I/O card changes have been
made. The wizard is typically used when upgrading I/O cards or controllers.
For each local port, you can specify:
• Whether to link an I/O card to an existing conguration
• Whether the I/O card is new hardware
• Whether to delete the conguration for a removed I/O card
The wizard guides you through the following actions:
• Associating I/O cards with existing port congurations
• Indicating which I/O cards are new hardware
• Deleting congurations 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 certied 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 conguration changes are complete.
Plan a Hardware Change
Upon boot, the Storage Center searches back-end targets for the conguration. Because a controller cannot boot without conguration
information, back-end access must be maintained during the controller replacement procedure. This can be done in two ways:
• Keep at least one common back-end slot/port dened and connected in the same manner on the new hardware conguration as it was
on the old hardware conguration.
• Connect the back-end to a port that is undened on the new hardware conguration. Storage Center is able to detect iSCSI targets
and acquire the boot conguration from the drives even though the slot/port is marked as undened.
When the appropriate back-end slot/port is identied, record this information on the Port Usage Work Sheet and continue the upgrade
process.
