Managing Front-End I/O Port Hardware
Front-end FC and iSCSI ports can be renamed and monitored with threshold definitions. iSCSI ports can be assigned network
configuration and tested for network connectivity.
For a Storage Center in virtual port mode, the Hardware tab displays a virtual port for each physical port. For physical ports, the physical
identity, speed, and hardware are given. For virtual ports, the current and preferred physical ports are shown.
NOTE: For user interface reference information, click Help.

Change the Preferred Physical IO Port for a Virtual IO Port
Under normal operating conditions, a FC or iSCSI virtual port is hosted by its preferred physical port.
Prerequisites
The fault domain must be configured for virtual port mode.
• If a Storage Center has IO ports with different performance characteristics, you may want to configure a virtual port to use a
particular physical port.
• If a physical port is removed from a Storage Center, the corresponding virtual port must be assigned to a different physical port.
• A single physical port can be the preferred port for multiple virtual 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.
