To check the Name Server (NS)

1. Enter the nsShow command on the switch to which the device is attached:

2. Look for the device in the NS list, which lists the nodes connected to that switch, allowing you to

determine if a particular node is accessible on the network.

•If the device is not present in the NS, the problem is between the storage device and the switch.

There might be a time-out communication problem between edge devices and the Name Server, or

there might 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. You should 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 might

be a zoning mismatch or a host/storage issue. Proceed to ”To check for zoning problems” on

page 312.

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.

The Local Name Server has 9 entries {
