Figure 3 on page 29 and the examples that follow show two possible mappings.
Figure 3 HACMP configuration example
.
Example 1
The application OracleRG corresponds to an HACMP resource group OracleRG, which consists of
the volume groups ora1vg and ora2vg. The corresponding XP RAID Manager device group oracle
controls all disks which form the volume groups of the HACMP resource group. The resource group
is configured to wait for a pair resynchronization in case you have not done any disk pair recovery
after the resource group has been moved to an alternate system. The resource group will be brought
online on the local system again (ApplicationStartup object is set to RESYNCWAIT). The AutoRecover
object is set to NO, which means that you will not utilize XP Cluster Extension capabilities to
automatically recover suspended disk pair states. The DataLoseMirror object and DataLoseDataCenter
object are set to NO, which means XP Cluster Extension will not allow you to bring the resource group
online if the disk pair is suspended or a takeover operation leads to a suspended disk pair.
Example 2
The application SapRG uses the device group sap to control all the disks of the corresponding HACMP
resource group SapRG, which uses the volume group sap1vg and sap2vg. The resource group is
configured to fail back to the remote system rather than waiting for a pair resynchronization, in case
you have not done any disk pair recovery after the resource group has been moved to an alternate
system. The resource group will be brought online on the local system again (ApplicationStartup object
is set to FASTFAILBACK per default). This setup will lead to an error loop, as HACMP does not
provide the feature to automatically failback after an error has been reported. The AutoRecover object
is set to NO by default, which means that you will not utilize XP Cluster Extension capabilities to
automatically recover suspended disk pair states.
The following example shows the configuration file for examples 1 and 2:
