PRIMECLUSTER Installation and Administration Guide 4.2 (Linux for Itanium)

F.2 Deleting a Cluster Service

This section describes the procedure to be performed in the following cases:

• If userApplication is deleted

After carrying out the procedure indicated in this section, perform the "Associating Resources to a Cluster Service Instance" operations in the following cases:

• If the configuration of a cluster application is changed

• If a new IP address takeover is to be executed or if an IP address takeover is to be discontinued

• If a takeover IP address is changed

Operation Procedure:

1. Log in with the system administrator authority.

   Log in with the system administrator authority to one of the nodes of the cluster system.

2. Delete the IP address takeover resources.

   • Execute the "clgettree" command in the format shown below, and check the resource IDs of the IP address takeover resources. The resource classes of the IP address takeover resources are "SHD_Host" and "IP_Address." If resources of the "SHD_Host" and "IP_Address" resource classes are not output, the execution of the subsequent steps is unnecessary because there are no IP address takeover resources.

     # /etc/opt/FJSVcluster/bin/clgettree

   (Example) In the following case, the resource IDs of the IP address takeover resources are "29," "27" and "28."

   # /etc/opt/FJSVcluster/bin/clgettree

   Cluster 1 /

                Domain 2 RC9

                         Ethernet 26 hme0 ON

                                IP_Address 28 hme0:1 UNKNOWN

                         DISK 20 c0t0d0 UNKNOWN

   • If the previous procedure indicates that there is an IP address takeover resource, execute the "cldelrsc" command in the format shown below, and delete the IP address takeover resource. Execute this step only if there is an IP address takeover resource.

     # /etc/opt/FJSVcluster/bin/cldelrsc -r resource-ID-of-IP-address-takeover-resource(*)

     * For "resource-ID-of-IP-address-takeover-resource," specify all resource IDs of IP address takeover resources that were obtained with the previous "clgettree" command.

   (Example) If the resource IDs of the IP address takeover resources are "29," "27" and "28."

   # /etc/opt/FJSVcluster/bin/cldelrsc -r 29,27,28
