When there is a connection failure, use ASUS Storage Management to verify that ASUS DS300f G2 sees the
initiators. See “Viewing a List of FC Initiators on the Fabric” .
If ASUS DS300f G2 sees some initiators but not the one you want, the problem is most likely elsewhere in the
loop or fabric. If ASUS DS300f G2 does not see any initiators:
• Check all of the Fibre Channel connections
• Verify that all nodes are properly connected and powered
• Verify that the fabric router or switch is properly connected powered

Faulty SAS expansion connections are suspected when the link port counter reports a large number of bad link
errors.
Link errors can be caused by:
• Debris blocking the SAS cable connector
• A faulty SAS cable
• A faulty controller or I/O module SAS connector

To check for a bad controller or I/O module SAS connector:
1. With the subsystems online and I/Os running, access the CLI via serial or Telnet.
2. At the command prompt, type the following command and press Enter.
administrator@cli> sasdiag -a errorlog -l expander -e 1 -i 1
3. At the command prompt, type the following command and press Enter.
administrator@cli> sasdiag -a errorlog -l c2cport
By interpreting the two error logs, you can verify which controller or I/O module SAS port is accumulating
link errors.

If you successfully setup and connected to ASUS Storage Management, then suddenly you can no longer
connect, it might be the result of the following three conditions:
• DHCP is enabled on your ASUS DS300f G2’s virtual management port
• The DHCP server does not have a dedicated IP address for the ASUS DS300f G2
• The ASUS DS300f G2 restarted and your DHCP server assigned a new IP address
You must obtain the new IP Address for the virtual management port in order to direct your browser to the
ASUS DS300f G2 and start ASUS Storage Management.
To access the new IP address:
1. Start your PC’s terminal VT100 or ANSI emulation program.
2. Press Enter once to launch the CLI.
3. At the Login prompt, type administrator and press Enter.
4. At the Password prompt, type password and press Enter.
