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 /ifs/data/Isilon_Support by running the following command:

cd /ifs/data/Isilon_Support

3. Run the following command to capture all input and output from the session:

screen -L

This will create a file named screenlog.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.

Check the status of your ICAP servers by running the following commands for your version of OneFS:

OneFS 8.0 through 8.1

Run the following command to list all ICAP servers:

isi antivirus servers list

To view the status of the ICAP servers, run the following command for each ICAP server, where

<URL> is the URL of the ICAP server listed in the output from above:

isi antivirus servers view <URL>

Accessible ICAP servers will show a Status of active.

OneFS 7.1 through 7.2

isi avscan config

Accessible ICAP servers will show a Status of alive.

See Appendix C for example output.

Do you

have any ICAP

servers?

Is each ICAP

server

accessible?

Yes

Go to Page 6Go to Page 6Yes

You must install and configure one

or more ICAP servers. For more

information about configuring an

ICAP server, see the Antivirus

chapter in the Isilon OneFS Web

Administration Guide for your

version of OneFS.

If you continue to experience issue

after installing and configuring ICAP

servers, restart troubleshooting at

the top of this page.

• Page 18 - AVScan takes an unusually long time to complete (2)

Test to see if one of the accessible ICAP servers are reachable from all cluster nodes. From

the OneFS CLI, run the following command, where <URL> is the URL of an ICAP server that

was listed as active or alive in the output from the commands on page 5:

isi_for_array -sX "nc -z <URL> 1344"

If the ICAP server is reachable from all cluster nodes, the output will look similar to the

following, with succeeded listed for each node:

cluster-1: Connection to 10.200.33.192 1344 port [tcp/*] succeeded!

cluster-2: Connection to 10.200.33.192 1344 port [tcp/*] succeeded!
