Updating View Objects

In any view, the values of the view properties represent the state of the server-side objects at the time the view was created. These property values are not updated automatically. In a production environment, the state of managed objects on the server is likely to change frequently. If your client script depends on the server being in a particular state (poweredOn or poweredOff, for example), then you can refresh the view object’s state. You can use the vSphere SDK for Perl Vim::update_view_data() subroutine to refresh the values of client-side views with server-side values. Example: Updating the State of View Objects uses Vim::update_view_data() to refresh view data.

Example: Updating the State of View Objects

#!/usr/bin/perl

use strict;

use warnings;

use VMware::VIRuntime;

. . .

# Get all VirtualMachine objects

my $vm_views = Vim::find_entity_views(view_type => 'VirtualMachine');

 

# Power off virtual machines.

foreach my $vm (@$vm_views) {

# Refresh the state of each view

$vm->update_view_data();

if ($vm->runtime->powerState->val eq 'poweredOn') {

$vm->PowerOffVM();

print " Stopped virtual machine: " . $vm->name . "\n";

} else {

print " Virtual machine " . $vm->name .

" power state is: " . $vm->runtime->powerState->val . "\n";

}

}
