Configuring priorities for LLT threads for AIX

On an highly loaded system, LLT threads might not be able to run because of relatively low priority settings. This situation may result in heartbeat failures across cluster nodes.

You can modify the priorities for the service thread by configuring kernel tunables in the file /etc/llt.conf

Note that the priorities must lie within the priority range. If you specify a priority outside the range, LLT resets it to a value within the range.

To specify priority value for LLT service thread

• Specify priority for the tunables by setting the following entry in the file /etc/llt.conf:

llt_thread_pri=<priority value>

Note that these changes take effect when the LLT module reloads.

Sample llt.conf file

llt_maxnids=32

llt_maxports=32

llt_nominpad=0

llt_basetimer=50000

llt_thread_pri=40
