Details on incompatibilities
Securing the dedicated monitoring disk area and setting the MonitorOnly attribute are not required when using a shared disk device.
Changes
Securing the dedicated monitoring disk area and setting the MonitorOnly attribute were required.
PRIMECLUSTER is fixed, which results in that unnecessary switchover due to failure detection is unlikely to occur even when I/O is overloaded, so the following is not required.
Securing the dedicated monitoring disk area and registering the area to the userApplication as an Fsystem resource
After migration from an earlier version, it is recommended to delete the dedicated monitoring disk area. Before deleting the area, disable the MonitorOnly attributes of all Fsystem resource.
However, after migration from an earlier version, the operation is also available in the configuration where the dedicated monitoring disk area is registered to the userApplication as an Fsystem resource. In this case, do not change the settings of the MonitorOnly attribute.
Note that this configuration does not allow cluster switchover if the Offline processing of Fsystem resources for other areas than the dedicated monitoring disk area fails while the Offline processing due to a resource failure and manual switchover is in progress.
Note
None.
