Extending a DataKeeper Resource
Field Tips
Target
Priority
Select or enter the Target Priority. This is the priority for the new extended
DataKeeper hierarchy relative to equivalent hierarchies on other servers. Any
unused priority value from 1 to 999 is valid, indicating a server’s priority in the
cascading failover sequence for the resource. A lower number means a higher
priority (1=highest). Note that LifeKeeper assigns the number “1” to the server on
which the hierarchy is created by default. The priorities need not be consecutive,
but no two servers can have the same priority for a given resource.
After receiving the message that the pre-extend checks were successful, click Next.
Depending upon the hierarchy being extended, LifeKeeper will display a series of information
boxes showingthe Resource Tags to be extended, some of which cannot be edited.
3. Click Next to launch the Extend Resource Hierarchy configuration task.
4. The next section lists the steps required to complete the extension of a DataKeeper resource
to another server.
Extending a DataKeeper Resource
1. After you have been notified that your pre-extend script has executed successfully, you will be
prompted for the following information:
Field Tips
Mount Point
Enter the name of the file system mount point on the target server. (This dialog
will not appear if there is no LifeKeeper-protected filesystem associated with the
DataKeeper Resource.)
Root Tag
Select or enter the Root Tag. This is a unique name for the filesystem resource
instance on the target server. (This dialog will not appear if there is no
LifeKeeper-protected filesystem associated with the DataKeeper Resource.)
Target Disk
or Partition
Select the disk or partition where the replicated file system will be located on the
target server.
The list of disks or partitions in the drop down box contains all the available
disks or partitions that are not:
l already mounted
l swap disks or partitions
l LifeKeeper-protected disks or partitions
The drop down list will also filter out special disks or partitions, for example, root
(/), boot (/boot), /proc, floppy and cdrom.
Note: The size of the target disk or partition must be greater than or equal to
that of the source disk or partition.
