2. Look for the device in the NS list, which lists the nodes connected to that switch. This allows
you to determine if a particular node is accessible on the network.
• If the device is not present in the NS list, the problem is between the device and the
switch. There may be a time-out communication problem between edge devices and the
name server, or there may be a login issue. First check the edge device documentation to
determine if there is a time-out setting or parameter that can be reconfigured. Also, check
the port log for NS registration information and FCP probing failures (using the
fcpProbeShow command). If these queries do not help solve the problem, contact the
support organization for the product that appears to be inaccessible.
• If the device is listed in the NS, the problem is between the storage device and the host.
There may be a zoning mismatch or a host/storage issue. Proceed to Chapter 9, “Zoning”.
3. Enter the portLoginShow command to check the port login status.
4. Enter the fcpProbeShow command to display the FCP probing information for the devices
attached to the specified F_Port or L_Port. This information includes the number of successful
logins and SCSI INQUIRY commands sent over this port and a list of the attached devices.
5. Check the port log to determine whether or not the device sent the FLOGI frame to the switch,
and the switch probed the device.
