Disabling CS Linux

Disabling the CS Linux software automatically stops the CS Linux node and its associated connectivity components. Disabling CS Linux also stops any other processes (such as an LUA application) from using CS Linux resources on this server.

In general, you should stop individual services as users finish using them, and only disable the system when there is no CS Linux activity.

If you need to disable CS Linux while users are active, warn users that CS Linux is stopping, and give them time to finish their activities before you disable the software.

When you disable the CS Linux software, applications using the APPC, CSV, LUA, NOF, or MS APIs are notified by a COMM_SUBSYSTEM_ABENDED return code and CPI-C applications by a CM_PRODUCT_SPECIFIC_ERROR return code.

To disable the CS Linux software, enter the following command at the Linux command prompt:

If CS Linux is disabled successfully, sna stop returns an exit code of 0. Any other exit code indicates that an error occurred and that the CS Linux software was not disabled. Refer to IBM Communications Server for Data Center Deployment on Linux Diagnostics Guide for more information about exit code values.
