LCMAP(8)LCMAP(8)NAMElcmap - determine path-ownership in a cluster
SYNOPSISlcmapDESCRIPTION
NetWorker software in a clustered environment needs to determine a map‐
ping 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-owner‐
ship 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 net‐
worker.cluster(8) 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;
