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.
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 IO card.
4. Replace, move, or remove the IO card(s) and reconnect as recorded on the Port Usage Work Sheet.
5. Plug in and power on the controller.
Manage IO Card Changes
After a change to an IO card in a Storage Center controller, the Congure IO Card Changes wizard applies old port congurations to
the new or modied ports. Changes can include replacing an IO card, moving the IO card to a dierent PCI slot, and removing an IO
card. Use the Congure IO Card Changes wizard to apply existing IO card port conguration settings to new or modied IO card
ports.
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. In the notication banner of the Summary tab, click Congure IO Card Change. The Congure IO Card Changes wizard
appears.
NOTE: If the controller must be restarted to move congurations to the other controller, the Congure IO Card
Changes wizard shows the option to restart the controller.
3. (Optional) Click Restart Controller.
4. Click Next.
5. From the Fibre Channel, iSCSI, or SAS table, identify ports that have been modied.
6. From the Card Location drop-down menu, select a port conguration.
7. Click Finish.
Add a UPS to a Storage Center
An uninteruptable power supply (UPS) provides power redundancy to a Storage Center. When a UPS is added to a Storage Center,
the status of the UPS appears in Storage Manager.
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. In the right pane, select Actions → UPS → Create UPS.
The Create UPS dialog box opens.
3. In the IPv4 Address eld, type the IP address of the UPS.
4. In the Community String eld, type the community string congured on the UPS. The default is Public.
5. From the UPS Type drop-down menu, select the brand of the UPS.
6. Click OK.
