Creating a snapshot of the cluster configuration

Edit online

You can initiate cluster snapshot creation from any cluster node. You can create a cluster snapshot on a running cluster. The cluster snapshot facility retrieves information from each node in the cluster. Accessibility to all nodes is required and the snapshot is stored on the local node.

About this task

To create a cluster snapshot, complete the following steps:

Procedure

  1. From the command line, enter smit sysmirror
  2. In SMIT, select Cluster Nodes and Networks > Manage the Cluster > Snapshot Configuration > Create a Snapshot of the Cluster Configuration and press Enter.
  3. Enter field values as follows:
    Table 1. Create a Cluster Snapshot of the Cluster Configuration fields
    Field Value
    Cluster Snapshot Name The name you want for the basename for the cluster snapshot files. The default directory path for storage and retrieval of the snapshot is /usr/es/sbin/cluster/snapshots. You can specify an alternate path using the SNAPSHOTPATH environment variable.
    Custom Defined Snapshot Methods Specify one or more custom snapshot methods to be executed if desired; press F4 for a picklist of custom methods on this node. If you select All, the custom methods will be executed in alphabetical order on each node.
    Save Cluster Log Files in a Snapshot The default is No. If you select Yes, PowerHA® SystemMirror® collects cluster log files from all nodes and saves them in the snapshot. Saving log files can significantly increase the size of the snapshot.
    Cluster Snapshot Description Enter any descriptive text you want inserted into the cluster snapshot. You can specify any text string up to 255 characters in length.
