HP P6000 Cluster Extension Software Administrator Guide (5697-0986, June 2011)

5 CLI commands and utilities
Using its CLI and command-line utilities, P6000 Cluster Extension can be integrated with almost any
cluster software for Linux and Windows operating systems.
CLI commands
The P6000 Cluster Extension CLI command clxevarun can be:
• Used as a standalone utility
• Integrated into any cluster software or custom application for Linux and Windows
clxevarun
Description Use clxevarun to manually prepare the application service's disk set before
an existing application service start procedure is invoked. You can use
clxevarun in custom solutions and startup scripts.
When using clxevarun, the status of the associated DR group is checked
to ensure that access to the vdisk(s) will occur under data consistency and
concurrency situations only.
You must invoke clxevarun before the application service disk set can be
activated; it is considered an online-only program. However, the CLI features
provide the same disaster recovery features as the integrated versions of
P6000 Cluster Extension.
Syntax clxevarun [–version] [–forceflag] app_name
Operands Displays the P6000 Cluster Extension version–version
–forceflag Force startup
app_name Application name configured in the UCF.cfg file
Example 1 This example assumes you have defined an APPLICATION tag named my-
exchange in the UCF.cfg file, and have specified all necessary objects,
including the DeviceGroup object, to map the DR group to the application
service my-exchange. P6000 Cluster Extension will check the vdisk set
mapped to the application service my-exchange, run the necessary failover
procedure, and generate a return code.
# clxevarun my-exchange
