	usage: $0 ($methods)

$0 manages a SAP HANA Instance as an HA resource.

The 'start'        operation starts the HANA instance or bring the "instance" to a WAITING (for primary) status
    The 'stop'         operation stops the HANA instance
    The 'status'       operation reports whether the HANA instance is running
    The 'monitor'      operation reports whether the HANA instance seems to be working in master/slave it also needs to check the system replication status
    The 'notify'       operation always returns SUCCESS
    The 'validate-all' operation reports whether the parameters are valid
    The 'methods'      operation reports on the methods $0 supports

<resource-agent name="SAPHanaTopology">
    <version>0.151.3</version>
    <shortdesc lang="en">Analyzes SAP HANA System Replication Topology.</shortdesc>
    <longdesc lang="en">This RA analyzes the SAP HANA topology and "sends" all findings via the node status attributes to
        all nodes in the cluster. These attributes are taken by the SAPHana RA to control the SAP Hana Databases.
        In addition it starts and monitors the local saphostagent.

1. Interface to monitor a HANA system: landscapeHostConfiguration.py
landscapeHostConfiguration.py has some detailed output about HANA system status
and node roles. For our monitor the overall status is relevant. This overall
status is reported by the returncode of the script:
0: Internal Fatal
1: ERROR
2: WARNING
3: INFO (maybe a switch of the resource running)
4: OK
The SAPHanaTopology resource agent will interpret returncodes 1 as NOT-RUNNING (or 1 failure) and returncodes 2+3+4 as RUNNING.
SAPHanaTopology scans the output table of landscapeHostConfiguration.py to identify the roles of the cluster node. Roles means configured and current role of the nameserver as well as the indexserver.

2. Interface is hdbnsutil
   The interface hdbnsutil is used to check the "topology" of the system replication as well as the current configuration
   (primary/secondary) of a SAP HANA database instance. A second task of the interface is the posibility to run a
   system replication takeover (sr_takeover) or to register a former primary to a newer one (sr_register).

3. saphostctrl
   The interface saphostctrl uses the function ListInstances to figure out the virtual host name of the
   SAP HANA instance. This is the hostname used during the HANA installation.
