Change the Hardware
Changing hardware follows these general tasks. Refer to upgrade documentation for the specic change for more detailed instructions.
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 aected 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 Congure I/O Card Changes wizard applies old port congurations to the
new or modied ports. Changes can include replacing an I/O card, moving the I/O card to a dierent PCI slot, and removing an I/O card.
Use the Congure I/O Card Changes wizard to apply existing I/O card port conguration settings to new or modied I/O card ports.
