fabric_vms 0.2.4.2

An addon for managing OpenVMS hosts with fabric

An addon for managing OpenVMS hosts with fabric. It wraps some of the methods available in Fabric enabling a user to execute commands on an OpenVMS (tested with OVMS 7.3 and 8.x releases) host.

Install

fabric_vms is on PyPI, so run:

pip install fabric_vms

Compatibility

There are no special requirements for the managed hosts, in particular GNV, vmspython are not required.

Only a subset of fabric’s commands are ported, pull requests are more than welcome.

As an additional feature, an extra module allows to run arbitrary commands on Xura’s v5 SMSC platform PML interpreter if imported as follows:

from fabric_vms import pml

Usage examples

An example of fabfile using fabric_vms.safe_run() wrapper:

fabfile.py

from fabric.api import env, task
from fabric.utils import puts

from fabric_vms import *
from fabric_vms import safe_run as run  # override fabric_vms.run

# Environmental settings
env.use_ssh_config = True
env.colorize_errors = True
env.hosts = ['menta']
env.user = 'SYSTEM'

@task(default=True)
def test():
    run('show device dsa /size /units=bytes')
    with cd('DSA0:[DELIVERABLES]'):
        run('md5sum packed_file.zip')

@task
def restart_snmp():
    run_clusterwide(['@SYS$STARTUP:TCPIP$SNMP_SHUTDOWN',
                     '@SYS$STARTUP:TCPIP$SNMP_STARTUP'])

@task
def stop_custom_services():
    run_clusterwide(['@SYS$STARTUP:STOP_SERVICES'])
    run('@T4$SYS:T4$STOP ALL')
    my_job = queue_job('HOUSEKEEPER')
    watchdog = queue_job('WATCHDOG')

    my_job.stop_queued_job()
    watchdog.stop_queued_job()

    # Check open files in DSA2, DSA3:
    for shadow_set in ['DSA2', 'DSA3']:
        open_files = lsof(shadow_set)
        if open_files:
            for _file in open_files:
                puts(_file)
