M.9.2 hvswitch command

Details on incompatibilities

In the forced startup (when using -f option) of a cluster application is issued, data corruption may occur if you start cluster applications when nodes where RMS is not running exist in the cluster. Therefore, to deal with this issue, the function is added. This function forcibly shuts down the nodes where RMS is not running before forced startup of cluster applications.

Changes

Before upgrading [PRIMECLUSTER 4.3A20]

When using -f option, RMS performs forced startup of cluster applications even if nodes where RMS is not running exist in the cluster and it may lead to data corruption.

After upgrading [PRIMECLUSTER 4.4A00]

In the use of -f option, when nodes where RMS is not running exist in the cluster, RMS performs the forced startup cluster applications after forcibly shutting down the nodes for reducing the risk of data corruption. However, if RMS failed to the forced shutdown, the forced startup of cluster applications are not performed.

Note

When using -f option, confirm "7.5.1 Notes on Switching a Cluster Application Forcibly " and then execute the command.
