To check the Simple Name Server (SNS):

1.

Issue the

nsshow

command on the switch to which the device is attached.

2.

Look for the device in the SNS 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 SNS, the problem is between the storage device and the switch.

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

Server. Check the edge device documentation to determine if there is a time-out setting or

parameter that can be reconfigured. If this does not solve the communication problem, contact the

support organization for the product that appears to be timing out.

• If the device is listed in the SNS, 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 185.

To check for zoning problems:

1.

Issue the

cfgactvshow

command to determine if zoning is enabled.

If zoning is enabled, it is possible that the problem is being caused by zoning enforcement (for

example, two devices in different zones cannot see each other).

2.

Confirm that the specific edge devices that need to communicate with each other are in the same

zone.
• If they are in the same zone, zoning is not causing the communication problem.

• If they are not in the same zone and zoning is enabled, proceed to

step 3
