NAME

lcmap - determine path-ownership in a cluster

SYNOPSIS

lcmap

DESCRIPTION

NetWorker software in a clustered environment needs to determine a mapping of a save path (filesystem or raw device) to the proper physical or virtual cluster client. This ensures that the data is saved to the correct NetWorker client name and facilitates recovery of a virtual NetWorker client irrespective of its current physical host. Path-ownership resolution also allows NetWorker server to identify with a virtual service in a cluster with its own configuration directory and become a highly available application when put under control of the cluster software.

A platform and cluster specific lcmap script is installed when the networker.cluster(1m) script is run in order to configure the NetWorker software as highly available. The lcmap script queries the cluster software and outputs to stdout the path-ownership information in the EMC Resource Administration Platform (RAP) format, which is cluster and platform independent. The lcmap script is called by NetWorker software whenever the path-ownership information needs to be determined or updated. The format of the output is NetWorker internal and can change between the releases. The script should not be modified manually.

EXAMPLES

The following is an example output from lcmap script:

        type: NSR_CLU_TYPE;

        clu_type: NSR_LC_TYPE;

        interface version: 1.0;

        type: NSR_CLU_VIRTHOST;

        hostname: chase;

        owned paths: /global/chase/nsr;

        type: NSR_CLU_VIRTHOST;

        hostname: hunt;

        owned paths: /global/hunt/data1, /global/hunt/data2;
