Test Network Connectivity for an iSCSI Port in a Fault Domain
Test connectivity for an iSCSI physical or virtual I/O port by pinging a port or host on the network.
Steps
1. If you are connected to a Data Collector, select a Storage Center from the drop-down list in the left navigation pane of
Unisphere Central.
2. From the
SYSTEM menu, click Ports.
The Ports view is displayed.
3. Click the Front End Ports tab.
4. Expand iSCSI, then select the physical port for which you want to test connectivity.
5. Click (More Actions) and select Ping.
The Ping dialog box opens.
6. Type the IP address of the host to which you want to test connectivity.
● If the host uses either IPv4 or IPv6 addressing, type the IP address of the host to which you want to test connectivity in
the IP Address field.
● If the host uses IPv4 addressing only, type the IPv4 address in the IPv4 Address field.
7. From the Ping Size drop-down menu, select a size in bytes for the ping packets, not including overhead. If you select
Other, type a value between 1 and 17000 bytes in the field below the menu.
NOTE: The Ping Size drop-down menu might not appear depending on the hardware I/O cards used by the Storage
Center.
8. Click OK. A message displays the results of the test.
9. Click OK.

Remove Ports from an iSCSI Fault Domain
To repurpose front-end iSCSI ports, remove the ports from the fault domain.
About this task
● If the front-end ports are configured for virtual port mode, the storage system must be running Storage Center 7.5.1 or later
to remove all ports from a fault domain.
● If the front-end ports are configured for virtual port mode, but the storage system is running a version of Storage Center
earlier than Storage Center 7.5.1, an error occurs if the port being removed is the last port in the fault domain.
● If front-end ports are configured for legacy mode, all the ports in a fault domain can be removed from a storage system
running any supported version Storage Center.
NOTE: You cannot remove the last port in the fault domain for an SCv2000 Series or SCv3000 Series system.
Steps
1. If you are connected to a Data Collector, select a Storage Center from the drop-down list in the left navigation pane of
Unisphere Central.
2. From the SYSTEM menu, click Ports.
The Ports view is displayed.
3. Click the Front End Ports tab.
4. Expand iSCSI, select an iSCSI fault domain, and click (Edit).
The Edit iSCSI Fault Domain dialog box opens.
5. In the Select Ports for the Faullt Domain table, click (Edit).
6. Select the port to remove from the table, then clear the Include in Fault Domain check box, and click Set.
