4.3.1.1 Configuring Resources for Resource Groups
Once you have defined resource groups, you further configure them by
assigning cluster resources to one resource group or another. You can
configure resource groups even if a node is powered down. However, SMIT
cannot list possible shared resources for the node (making configuration
errors likely).
The following describes the different possibilities for resources that might be
added to a resource group:
Table 20. Options Configuring Resources for a Resource Group
Service IP Label If IP address takeover is being used, list the IP label to be
moved when this resource group is taken over. Press F4
to see a list of valid IP labels. These include addresses
which rotate or may be taken over.
HTY Service IP Label NTX adapters are not supported by HACMP for AIX 4.3
File Systems Identify the file systems to include in this resource group.
Press F4 to see a list of the file systems. When you enter
a file system in this field, the HACMP for AIX software
determines the correct values for the Volume Groups and
Raw Disk PVIDs fields.
You cannot configure a resource group until you have completed the
information on the Add a Resource Group screen.
Note
If you configure a cascading resource group with an NFS mount point, you
must also configure the resource to use IP Address Takeover. If you do not
do this, takeover results are unpredictable.You should also set the field
value Filesystems Mounted Before IP Configured to true so that the
takeover process proceeds correctly.
Note
When setting up a cascading resource with an IP Address takeover
configuration, each cluster node should be configured in no more than
(N+1) resource groups on a particular network. Here, N is the number of
standby adapters on a particular node and network.
