Configure screen logging through SSH
We recommend that you configure screen logging to log all session input and output during your troubleshooting session. This log file can be shared with Isilon Technical Support, if you require assistance at any point during troubleshooting.
Note: The screen session capability does not work in OneFS 7.1.0.6 and 7.1.1.2. If you are running either of these versions, you can configure logging by using your local SSH client's logging feature.
1. Open an SSH connection to the cluster and log in by using the root account.
Note: If the cluster is in compliance mode, use the compadmin account to log in. All compadmin commands must be preceded by the sudo prefix.
2. Change the directory to / i f s/ dat a/ I si l on_Suppor t by running the following command:
cd / i f s/ dat a/ I si l on_Suppor t
3. Run the following command to capture all input and output from the session:
scr een - L
This will create a file named scr eenl og. 0 that will be appended to during your session.
4. Perform troubleshooting.
Before you begin
CAUTION!If the node, subnet, or pool that you are working on goes down during the course of troubleshooting and you do not have any other way to connect to the cluster, you could experience data unavailability.
Therefore, make sure that you have more than one way to connect to the cluster before you start this troubleshooting process. The best method is to have a serial console connection available. This way, if you are unable to connect through the network, you will still be able to connect to the cluster physically.
For specific requirements and instructions for making a physical connection to the cluster, see article 304071 on the EMC Online Support site.
Before you begin troubleshooting, confirm that you can connect through either another subnet or pool, or that you have physical access to the cluster.
