Administrator Guide

• 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 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.
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 Congure I/O Card Change.
NOTE
: If the controller must be restarted to move congurations to the other controller, the Congure I/O Card Changes
wizard shows the option to restart the controller.
The Congure 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 modied.
7 From the Card Location drop-down menu, select a port conguration.
8 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 is displayed in Storage Manager.
1 If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
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.
