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.
8. Click Finish.
