CP server deployment and migration scenarios describes the supported deployment and migration scenarios, as well as the required procedures to be performed on the VCS cluster and CP server node or cluster.
On the designated CP server, perform the following tasks: On the VCS cluster nodes, configure server-based I/O fencing. See the Veritas Cluster Server Installation Guide for the procedures. |
|||
Add a new VCS cluster to an existing and operational CP server |
On the VCS cluster nodes, configure server-based I/O fencing. See the Veritas Cluster Server Installation Guide for the procedures. |
||
Replace the coordination point from an existing CP server to a new CP server |
On the designated CP server, perform the following tasks:
See the Veritas Cluster Server Installation Guide for the procedures. On the VCS cluster nodes run the vxfenswap command to move to replace the CP server. See Replacing coordination points for server-based fencing in an online cluster. |
||
Replace the coordination point from an existing CP server to an operational CP server |
On the designated CP server, prepare to configure the new CP server manually. See the Veritas Cluster Server Installation Guide for the procedures. On the VCS cluster run the vxfenswap command to move to replace the CP server: See Replacing coordination points for server-based fencing in an online cluster. |
||
Enabling fencing in a VCS cluster with a new CP server Note: This procedure incurs application downtime on the VCS cluster. |
Existing VCS cluster with fencing configured in disabled or scsi3 mode |
On the designated CP server, perform the following tasks:
See the Veritas Cluster Server Installation Guide for the procedures. |
|
Refreshing registrations of VCS cluster nodes on coordination points without incurring application downtime |
Existing VCS cluster using the CP server as coordination point |
On the VCS cluster run the vxfenswap command to refresh the keys on the CP server. See Refreshing registration keys on the coordination points for server-based fencing. |
