Details on incompatibilities
The default value of the environment variable RELIANT_SHUT_MIN_WAIT which specifies the period (in seconds) until the hvshut command times out has been changed from 900 to INTMAX, in order to prevent the command from timeout in case of the default value.
Point
Since RMS terminates abnormally when hvshut command times out, resources under userApplication may remain running without having been stopped.
In this situation, if RMS on another node is started up and forced switch of the userApplication is performed, resources may be online on several nodes simultaneously, and then data corruption could occur if the resource manages shared disks.
Changes
In the case that the environment variable RELIANT_SHUT_MIN_WAIT is set to the default value, if the resource offline processing invoked by the hvshut command is not completed within 900 seconds, the command timeouts and RMS terminates abnormally. In this instance, the resource may remain running without having been stopped.
In the case that the environment variable RELIANT_SHUT_MIN_WAIT is set to the default value, the resource offline processing invoked by the hvshut command terminates abnormally, and then RMS terminates.
Note
When using RMS, you need to change the environment variable to the value corresponding to the configuration setup.
