Determine the IB Path Continuity

If you have root access to the fabric, you can log in as the root user and use the ibclear errors command and then the ibcheckerrors command to reset all the IB error counters. This action starts a fresh statistics-gathering session. This step is not mandatory, but if you decide to perform it, log out and log back in to the fabric as the admin user to run the show ib-path stats command.

This procedure is for the CLI.

1. Determine which server is experiencing problems.
2. Log in to the fabric as the admin user.
3. Verify that the server appears in the resulting list.

   Type the show ib path-stats command without any qualifiers and press Tab or a question mark (?). For example:

   [OFOS] show ib path-stats ?
   Possible completions:
       10e08508ac0005  Port Guid of host nsn178-42
       10e085095a0005  Port Guid of host nsn178-76
       10e08b53a80005  Port Guid of host leaf_01
       10e09a86500005  Port Guid of host hca-10e09a86500004
       2c9030057b4de   Port Guid of host nsn178-32

4. Clear the counters on the server to get a fresh batch of statistics.

   For example:

   show ib path brick -clear

5. Display the IB path and counters.

   See the example in Determine the IB Path Continuity.
