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
In the environment where the environment variable RELIANT_SHUT_MIN_WAIT remains in default and the shutdown processing of a resource by the hvshut command has not been completed in 900 (seconds), the command times out and then RMS ends abnormally. The resource does not stop and remains running at this time.
In the environment where the environment variable RELIANT_SHUT_MIN_WAIT remains in default, the hvshut command does not time out even when the shutdown processing of a resource by the command has not been completed.
Note
When using RMS, make sure to change this environment variable to suite the configuration setting.
