LKU broadcast message disablement

Edit online

Currently, Live Kernel Update (LKU) notifies all the active sessions of an logical partition (LPAR) on the system about the LKU operations by sending a broadcast message. All the users who are logged in to the system need not be aware of the LKU operations. If you do not want to be notified about the LKU operations, disable the LKU broadcast messages.

The LKU broadcast messages can be enabled or disabled by setting one of the following values for the disable_wallmsg LKU tunable parameter in the lvupdate.data file:
  • yes: Disables the LKU broadcast messages.
  • no: Enables the LKU broadcast messages. This is the default value.
If the value of the disable_wallmsg LKU tunable parameter is left blank then the LKU broadcast messages are enabled.
Note: For more information about lvupdate.data file, see Configuring resources for Live Update.
