Adding Resource Script Search and Replace Values
To enable a resource for business continuity, certain values (such as IP addresses) specified in
resource load and unload scripts need to be changed in corresponding resources in the other clusters.
You need to add the search and replace strings that are used to transform cluster resource load and
unload scripts from this cluster to another cluster.
TIP: You can see the IP addresses that are currently assigned to resources by entering the display
secondary ipaddress command at the NetWare server console of cluster servers.
The search and replace data is cluster specific, and it is not synchronized via DirXML between the
clusters in the business continuity cluster.
To add resource script search and replace values:
1 In the Resource Script Replacements section of the Business Continuity Cluster Properties
2 Add the desired search and replace values, then click OK.

2.9.4 Configuring Cluster Resources for Business Continuity

Cluster resources can be configured for business continuity either at the same time they are created
or after they are created. Configuring a resource for business continuity consists of enabling that
resource for business continuity, adding load and unload script search and replace data specific to
the resource, and selecting peer clusters for the resource.
NOTE: In a business continuity cluster, you should have only one NSS pool for each LUN that
could be failed over to another cluster. This is necessary because in a business continuity cluster,
entire LUNs fail over to other clusters, rather than individual pools, which fail over to other nodes
within a cluster.

When specifying a username, include the Novell eDirectory context for it.
If you selected multiple peer clusters, specify a common administrator username and password
for the selected peer clusters. Each cluster can then use the same username and password to
connect to multiple peer clusters.
Step 1 and Step 2
Step 1 in the
page, click New.
The search and replace values you specify here apply to all resources in the cluster that have
been enabled for business continuity.
For example, if you specified 10.1.1.1 as the search value and 192.168.1.1 as the replace value,
the resource with the 10.1.1.1 IP address in its scripts would be searched for in the primary
cluster and, if found, the 192.168.1.1 IP address would be assigned to the corresponding
resource in the secondary cluster.
You can also specify global search and replace addresses for multiple resources in one line.
This can be used only if the last digits in the IP addresses are the same in both clusters. For
example, if you specify 10.1.1 as the search value and 192.168.1 as the replace value, the
software finds the 10.1.1.1, 10.1.1.2, 10.1.1.3 and 10.1.1.4 addresses and then replaces them
with the 192.168.1.1, 192.168.1.2, 192.168.1.3, and 192.168.1.4 addresses, respectivley.
for the other cluster that this cluster will migrate resources to.
