Fabric OS 5.x administrator guide

Verifying device connectivity

Connect to the switch and log in as admin.

Optional: Issue the

switchShow

command to verify that devices, hosts, and storage are connected.

Optional: Issue the

nsShow

command to verify that devices, hosts, and storage have successfully

registered with the Name Server.

Issue the

nsAllShow

command.

The 24-bit Fibre Channel addresses of all devices in the fabric are displayed. For example:

The number of devices listed should agree with the number of devices that are connected.

Tracking and controlling switch changes

The TC feature allows you to keep a record of specific changes that might not be considered switch

events, but might provide useful information. The output from the TC feature is dumped to the system

messages log for the switch. Use the

errDump

errShow

command to view the log.

Items in the log created from the TC feature are labeled

TRCK

Trackable changes are:

•

Successful login

•

Unsuccessful login

•

Logout
