Verifying iSCSI connections

Verify that the connections between a primary HA host or secondary HA host and an iSCSI device are operational

1. Using SSH, log in to the primary or secondary HA host as the root user.
2. To test the connection to your iSCSI storage device, type the following command:

   ping iSCSI_Storage_IP_Address

3. Verify the iSCSI service is running and that the iSCSI port is available by typing the following command:

   telnet iSCSI_Storage_IP_Address 3260

   Note: The default port is 3260.
4. Verify that the connection to the iSCSI device is operational by typing the following command:

   iscsiadm -m node

   To verify that the iSCSI device is correctly configured, you must ensure that the output that is displayed for the primary HA host matches the output that is displayed for the secondary HA host.

   If the connection to your iSCSI volume is not operational, the following message is displayed:

   iscsiadm: No records found

5. If the connection to your iSCSI volume is not operational, then review the following troubleshooting options:
   • Verify that the external iSCSI storage device is operational.
   • Access and review the /var/log/messages file for specific errors with your iSCSI storage configuration.
   • Ensure that the iSCSI initiatornames values are correctly configured by using the /etc/iscsi/inititatorname.iscsi file.
   • If you cannot locate errors in the error log, and your iSCSI connections remain disabled, then contact your Network Administrator to confirm that your iSCSI server is functional or to identify network configuration changes.
   • If your network configuration has changed, you must reconfigure your iSCSI connections.
