Test Network Connectivity for an iSCSI Port
Test connectivity for an iSCSI I/O port by pinging a port or host on the network.
About this task
NOTE: If multiple virtual fault domains (VLANs) are associated with the port, the physical fault domain is used for ping
tests issued from the Hardware tab. To test network connectivity for a VLAN, initiate a ping test from a physical port in a
fault domain on the Storage tab.
Steps
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. Click the Hardware tab.
3. In the Hardware tab navigation pane, expand Controllers→ controller_name → IO Ports→ iSCSI, then select the iSCSI I/O
port.
4. In the right pane, click Ping Address. The Ping Address dialog box opens.
5. If the port uses an IPv4 address, in the IPv4 Address eld, type the IP address of the host to which you want to test
connectivity.
6. If the port uses either an IPv4 or IPv6 address, in the IP Address eld, type the IP address of the host to which you want to
test connectivity.
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 eld 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.
NOTE: If the physical or virtual port is located on a Chelsio iSCSI card, the rst ping test to a specic IP address
fails and displays the error SendPing: No ARP entry for nn.nn.nn.nn, sending ARP now. Try
again later.
Run the ping test again to verify connectivity.
9. Click OK to close the message.

Set Threshold Alert Denitions for a Front-End IO Port
Congure one or more Threshold Alert Denitions for an IO port if you want to be notied when an IO port reaches specic
bandwidth or latency thresholds.
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. Click the Hardware tab.
3. In the Hardware tab navigation pane, expand Controllers→ controller name→ IO Ports→transport type, then select the IO port.
4. In the right pane, click Set Threshold Alert Denitions. The Set Threshold Alert Denitions dialog box opens.
5. Select the alert denition for which you want to congure a threshold alert, then click Create Threshold Denition. The Create
Threshold Denition dialog box appears.
6. Congure the threshold denition attributes as needed, then click OK. These attributes are described in the online help.
7. From the Available Alert Denitions table, select the new Threshold Alert Denition.
8. (Optional) To remove the Threshold Alert Denition, hold Ctrl and click the selected Threshold Alert Denitions.
9. Click OK to close the Set Threshold Alert Denitions dialog box.
Congure Front-End IO Ports (SAS and Fibre Channel)
On SCv2000 series controllers, ports must be congured before they can be used as front-end ports. After Storage Manager
congures the port, it is also added to a fault domain.
Prerequisites
• The Storage Center must be a SCv2000 series storage system.
