Details on incompatibilities
The default value of the environment variable RELIANT_SHUT_MIN_WAIT, which sets the timeout duration of the hvshut command, is changed from 900 (seconds) to 2147483647 (seconds). With this change, even if you leave the environment variable to default, the command will not timeout.
Point
A resource in a cluster application does not stop and may remain running because the RMS ends abnormally when the hvshut command times out.
In this situation, data corruption may occur when RMS and cluster application with the resource is forcibly started on another node, if shared disk is controlled by the resource. This is because the resource is started on multiple nodes at the same time.
Changes
If the resource offline processing invoked by the hvshut command is not completed within 900 seconds in an environment where the RELIANT_SHUT_MIN_WAIT environment variable is set to its default value, the command times out and then RMS terminates abnormally. In this case, the resource remains running without stopped.
In an environment where the RELIANT_SHUT_MIN_WAIT environment variable is set to its default value, the command will not time out even if stop process using the hvshut command is not completed.
Note
When using RMS, you need to change the environment variable to the value corresponding to the configuration setup.
