Storage Center Alert: How to Troubleshoot a Storage Center iSCSI Port Down

Storage Center has reported a port as being down.

• If the port is not in use:  To clear the alert, right-click the alert and select "Acknowledge Alert."
• If the port is in use:  Use these instructions to troubleshoot.

Review any recent network or environment changes to ensure that they are not responsible for the connection issue.

Follow these steps to verify which ports are down.

1. In Enterprise Manager, click the Storage view.
2. In the Storage pane, select the Storage Center.
3. Click the Hardware tab.
4. In the Hardware tab navigation pane, expand Controllers→ controller name→ IO Ports.
5. Note whether the ports are up or down.

1. Log in to the switch used for iSCSI and disable/enable switch port in which the array port is plugged into. 
   NOTE: Before disabling the port, verify it shows down, if the port is listed as up, the port may not be the correct port.
2. Reseat the cable on both ends.  Before reseating the cable, verify it is the correct one, the link or speed LED should not be illuminated.
3. Reseat the SFPs on the switch and array (if present).
4. Replace the cable with a known good cable.
5. Test with a known good SFPs on the switch and array (if present).
6. Move the cable to a different switch port.  If this resolves the issue, depending if VLANs are implemented, the VLAN may need to be updated to establish the connection.

If the issue is not resolved, and the port is still down, contact your service provider.
