Im using the following powerCLI script to display:
VM Name
Uptime
Operating system
However the operating system part of the script returns a blank value.
#connect to server, setup reportfile
$VIServer="servername"
Connect-VIServer -Server servername
$stat = 'sys.osuptime.latest'
$entity = Get-VM
Get-Stat -Entity $entity -Stat $stat -Realtime -MaxSamples 1 -ErrorAction SilentlyContinue |
Select #{N='VM';E={$_.Entity.Name}},
#{N='Uptime (d.hh:mm:ss)';E={[timespan]::FromSeconds($_.value)}},
#{N=”Configured OS”;E={$_.ExtensionData.Config.GuestFullname}}
Output:
VM : VM_EXAMPLE
Uptime (d.hh:mm:ss) : 00.07:29:04
Configured OS :
If I run:
Get-VM | Select #{Label = "VM Name" ; Expression = {$_.Name} },#{N=”Configured OS”;E={$_.ExtensionData.Config.GuestFullname}}
The operating system displays fine.
Any ideas on how I can get the os to display?
You're piping in the Get-Stat Which doesn't contain the details in the $entity variable.
... | Select #{N='VM';E={$_.Entity.Name}},
#{N='Uptime (d.hh:mm:ss)';E={[timespan]::FromSeconds($_.value)}},

I have a server running Perl and an Apache web server.
I wrote a script which closes running instances of perl.exe and then launches them again, with some system() commands.
When I try and run it from a browser it works as expected, closes all running perl.exe, but then it doesn't restart them with my system("start my_script.pl").
This is my script running from the browser.
#!/Perl/bin/perl
use lib "/Perl/ta/mods" ;
# http://my_domain.com/cgi-bin/myscript.pl?
use CGI::Carp qw(fatalsToBrowser);
use IPC::System::Simple qw(system capture);
use Win32::Process::List;
my $script_to_end = "start \path_to_script\myscript.pl" ;
system($script_to_end);
print "done" ;
exit;
This launching myscript.pl which does the following:
#!/Perl/bin/perl
use strict;
use warnings;
use lib "/Perl/ta/mods" ;
use Win32::Process::List;
my $script = 'io.socket' ;
my #port = (4005,5004) ;
my $scriptpath_4005 = "Perl C:\\path_to_script\\$script.pl $port[0]";
my $scriptpath_5004 = "Perl C:\\path_to_script\\$script.pl $port[1]";
our $nmealogger = "C:\\nmealogger\\nmealogger.exe";
system('TASKKILL /F /IM nmealogger* /T 2>nul');
print "current running perl instance: $$\n" ;
my $P = Win32::Process::List->new(); #constructor
my %list = $P->GetProcesses(); #returns the hashes with PID and process name
foreach my $key ( keys %list ) {
unless ($list{$key} eq 'perl.exe') { next ; }
# $active_perl_pid{$key} = 1 ;
print sprintf("%30s has PID %15s", $list{$key}, $key) . "\n\n";
if ($$ == $key)
{
print "current running perl instance: $key\n";
next;
} else {
print "kill: $key\n";
system("TASKKILL /F /PID $key");
# system('TASKKILL /F /IM powershell* /T 2>nul');
}
}
system "start $nmealogger" ;
system "start $scriptpath_4005";
system "start $scriptpath_5004";
use common_cms;
exit;
This works fine if I run it from the machine, kills all perl.exe and re-launches perl.exe, but running from the browser it only kills them but never re-launches them.
I thought it could be to do with the httpd.conf settings but I'm not sure.
Any help would be greatly appreciated.
Thanks
Update: I couldn't get around this issue so took a different approach.
Ended up changing the script running from the browser to write a log file on the server and created a scheduled task that runs every minute to check if that file exists, which then kicks of my script on the server.
Quite a long way around but hey it works.
Thanks for the suggestions, much appreciated.
"start" runs the script in a new command window, correct? Presumably Apache is a service, please see related https://stackoverflow.com/a/36843039/2812012.
How can I recompose a VM v1 with existing parent VM v2's snapshot s2 ?
After referring few documents, I saw command Send-LinkedCloneRecompose for recomposing VM.
I am trying this command as follows:
$myVM = 'v1'
$clone = Get-DesktopVM -Name $myVM
$pool = Get-Pool -pool_id $clone.pool_id
$date = Get-Date
$date = $date.AddSeconds(10)
Write-Host "Recomposing" $clone.name
Send-LinkedCloneRecompose -machine_id $clone.machine_id -parentVMPath $pool.parentVMPath -parentSnapshotPath $pool.parentVMSnapshotPath -schedule $date -forcelogoff $true | tee-object -variable vmState
Here I am getting error as Get-DesktopVM : The term 'Get-DesktopVM' is not recognized as the name of a
cmdlet, function, script file, or operable program. Check the spelling of the
name, or if a path was included, verify that the path is correct and try again.
I am getting the same error for powercli commandlets Get-Pool and Send-LinkedCloneRecompose as well.
I am using VMware VSphere power cli 5.5 release 2 patch 1.
Can anyone please help me in understanding the problem here ?
I missed to add
& "C:\Program Files\VMware\VMware View\Server\extras\PowerShell\add-snapin.ps1"
before executing above commands. So the commandlets were not recognized.
Error: Starting VM on XenServer after migration(export and then import)
This operation cannot be performed because the specified virtual disk could not be found.
Basically when we export the vm and then import to other xenserver, sometime found the above issue.
If you go to the vm console tab using xencenter you can see the DVD drive is blank, you should have to empty that by clicking on eject.
via xe command:
xe vm-cd-list uuid={vmUUID} | grep "empty" | awk '{print $4}
if it returns false (it means the DVD drive is not empty) then run this command:
xe vm-cd-eject uuid={vmUUID}
I am trying to run a script on VxWorks Shell, which will load a module.
I use a Perl script to telnet into the system, login and get access to the shell.
I am able to run the basic commands like 'i', 'time', 'ls' 'pwd' and 'h' and so on.
But I would like to run a script, say 'test.o'.
If I do : <C:\Path\subfolder\test.o the script file WILL run from, the TORNADO Shell.
But I have connected to using Telnet using Perl.
So I connect this way:
use Net::Telnet;
my $username = "username";
my $password = "password";
my $t = new Net::Telnet(Timeout=>10, Errmode=>'die');
$t->open('10.42.177.123');
$t->login($username,$password); # Logins as expected.
my #lines = $t->cmd('i'); # To test
print #lines # This works
#lines = $t->cmd('<C:\\Path\\Subfolder\\test.o'); # This is not working for me. HELP!
print #lines; # Prints the Error below
I get an error saying :
Unknown directory: /C:\Path\Subfolder
can't open input 'C:\Path\Subfolder\test.o
errno = 0x1f5
-
How do I run my script file if it is residing at a particular folder of the host PC?
I am able to run the script manually from the TORNADO SHELL window where the prompt looks like ->. and hence it is a working script. And as I have said, I am able to run and print the basic VxWorks Shell commands ("build-in functions").
Any help? [ My OS is Win7 ]
Thanks!
This is issue is now resolved. Two issues was there, and one was because TORNADO, another VxWorks Client was also logged into the system at the same time, while I am trying run my perl script which sends commands and do instructions using Telnet, and having two clients (Tornado, and my scripts Telnet session) running at the same time (despite the VxWorks OS running on the Embedded system having TelnetDeamon running) it didn't like it.
As for the Error above, why it didn't work and gave an error was a syntax error. I should have used
$t->cmd('<\\Path\\subfolder\\test.o');
No need to give C:

Please guide what shall I do to run IIS administration scripts.
Below link says Powershell SnapIn is not available for IIS 6.0:
http://forums.iis.net/p/1156851/1903821.aspx#1903821
WMI is the option to go with IIS 6.0 administration.
But WMI is not the option for me as soon we will be upgrading to IIS 7.5
In IIS6 on Windows 2k3 platform, I suggest you try accessing IIS via the old WMI provider ("Microsoftiisv2") or ADSI provider as both are accessible from the PowerShell.
Neither snapins nor WebAdministration module is available for IIS 6.0, so we can access IIS6 metabase from PowerShell using either
For IIS7.0, we can "import WebAdministration" module.
For example, I had to set the physical path for a virtual directory for IIS6, so I made use of a vbs script,iisvdir that comes along with IIS6 in c:/Windows/System32 .
Copying the code snippet
Function resetSiteLocation ($newPath)
{
Write-Host "List of Virtual directories for the site Test123 before reset :"
C:\WINDOWS\system32\iisvdir /query Test/Test123
Write-Host "About to reset site location"
C:\WINDOWS\system32\iisvdir /delete Test/Test123/Test1
C:\WINDOWS\system32\iisvdir /create Test/Test123 Test1 C:\projects\Test\Test123\Test1
C:\WINDOWS\system32\iisvdir /delete Test/Test123/Test2
C:\WINDOWS\system32\iisvdir /create Test/Test123 Test2 C:\projects\Test\Test123\Test2
Write-Host "Finished to reset site location"
Write-Host "List of Virtual directories for the site Test123 after reset :"
C:\WINDOWS\system32\iisvdir /query Test/Test123
}
Since you would be making a switch to higher version of IIS, you could put a switch in your code to determine the IIS version and take action as appropriate.
I did this:
Write-Host "Checking Installed IIS version:"
$iisVersion = Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\InetStp";
Write-host IIS major version : $iisVersion.MajorVersion
Write-host IIS minor version : $iisVersion.MinorVersion
Write-Host "Finished the check."
## IIS inclusion module
## Neither snapins nor WebAdministration module is available for IIS 6.0, so we can access IIS6 metabase
## from PowerShell using either old WMI provider ("Microsoftiisv2") or ADSI provider as both are accessible from the PowerShell.
## For IIS7.0, we can import WebAdministration module
if (($iisVersion.MajorVersion -eq 7 ) -or ($iisVersion.MajorVersion -ge 7 ))
{
Write-host Detected IIS Major Version : $iisVersion.MajorVersion and Minor version : $iisVersion.MinorVersion. Hence importing WebAdministration module.
Import-Module WebAdministration;
Write-Host "About to reset app pool"
Restart-WebAppPool("Application")
Write-Host "Finished resetting app pool"
resetSiteLocation
Write-Host "About to reset site"
Restart-WebItem("IIS:\Sites\My application")
Write-Host "Finished to reset site"
}
elseif ($iisVersion.MajorVersion -eq 6)
{
Write-host IIS version 6 detected. Hence accessing IIS metabase using old WMI provider
##2. Reset App Pool
Write-Host "About to reset app pool"
Write-Host "Finished resetting app pool"
##3. Reset site location
resetSiteLocation
##4.Reset site
Write-Host "About to reset site"
Write-Host "Finished to reset site"
}
else
{
Write-host Detected IIS $iisVersion.MajorVersion
}

Here is some good information on using the WMI interface with IIS 6:
http://network-nick.blogspot.com/2015/01/powershell-and-iis-6.html
He also points to the Microsoft documentation of cmdlets for this environment, here:
https://learn.microsoft.com/en-us/previous-versions/iis/6.0-sdk/ms525265(v=vs.90)
During the article he develops and explains the following PowerShell script for listing a server's web sites and their virtual directories. I actually tried this and it works.
$WebSiteID = Get-WmiObject -Namespace "root/MicrosoftIISv2" -Class IIsWebServer | Select-Object -ExpandProperty Name
ForEach ( $Site in $WebSiteID ) {
$WebSiteName = Get-WmiObject -Namespace "root/MicrosoftIISv2" -Class IIsWebServerSetting | Where-Object { $_.Name -like "$site" } `
| Select-Object -Expandproperty ServerComment
write-host "`r`n" $WebSiteName
$AppPath = Get-WmiObject -Namespace "root/MicrosoftIISv2" -Class IIsWebVirtualDirSetting | Where-Object { $_.Name -like "$site/*" } `
| select -expandproperty path
$AppPath = $AppPath | select-object -unique | sort-object
$AppPath
}
