SCOM - a link to an article I wrote on How to Play Sound Alerts on SCOM Console

One of the problems with System Center Operation Manager console is the lack of sound alerts.
I wrote an article a while back on how to implement a sound alert for events.

Here is the link from perti.co.il - http://www.petri.co.il/play-sound-alerts-on-microsoft-system-center-operations-manager-console.htm

Xen Server environment mapping script

Hello,

do you want a basic xen server environment mapping script ?, you got it.
for starting it will list all the hosts and guests, in the future I will add UUID and more...

================================
echo off
set user=[]
set password=[]
set server=[]

del auto_host_list.txt /q
del auto_vm_list.txt /q

"C:\Program Files\Citrix\XenCenter\xe.exe" -s %server% -u %user% -pw %Password% host-list params=name-label,uuid >auto_host_list1.txt
for /f "tokens=1,2,3,4 delims=( " %%A in (auto_host_list1.txt) do (echo %%D >> auto_host_list.txt)

"C:\Program Files\Citrix\XenCenter\xe.exe" -s %server% -u %user% -pw %Password% vm-list params=name-label >auto_vm_list1.txt
for /f "tokens=1,2,3,4 delims=( " %%A in (auto_vm_list1.txt) do (
if NOT %%D==Control echo %%D  >> auto_vm_list.txt
)

del auto_host_list1.txt /q
del auto_vm_list1.txt /q

XenServer disaster recovery script in batch

Hi all,
I wanted to make my life easier when the disaster will hit (and between you and me it allays a meter of time) so I wrote a menu driven disaster recovery script.
The script is covering:

1. Pool Master failure
2. Host Member Failure
3. resetting the power state of VM's
4. Recovering them to another HOST

My goal was giving a simple name based actions rather than using UUID's.

You will need 2 more files that create your environment:

1. host_list.txt - all the hosts and their role, one each line. example: [servername, member]
2. vm_list.txt - all the vm

Those 2 files are case sensitive so be sure to write the names correctly.
Note: in host_list.txt the role should be in lower letters (member/master)

To help you I saved it also as a GoogleDoc.

Any comments/improvements will be welcomed...

Xen Server Automatic Host backup script using batch

Hi,

You can never be too carefull, here is an automated backup script for xen server host.
Be careful, it can reach to 1G... (Mine did).

as always you will need a list file with the names of the xen hosts (case sensitive), name it host_list.txt.
and the following: (this will keep 2 versions, you can remove those lines if you want)
replace [] with your data.
====================================
for /f %%A in (host_list.txt) do (
del "D:\Backup\XenServer\OLD_%%A_Backup.bak" /q
ren D:\Backup\XenServer\%%A_Backup.bak Old_%%A_Backup.bak
"C:\Program Files\Citrix\XenCenter\xe.exe" -s [server ip] -u [user] -pw [password] host-backup host=%%A file-name=D:\Backup\XenServer\%%A_Backup.bak
)
====================================

Automatic script for Xen Coalesce (gain space back after using snapshots)

If you are using snapshots in XenServer you may noticed a spaced beed used on the storage that you cannot explained.
This is due to using snapshots. After you create the initial snapshot xen will continue writing to it even if it is not there.
To reclaim the space the VM's VDI need to go a proccess named "Coalesce" which integrates the data from the snapshot into the original VDI.

I used article CTX123400 to base my script on.
Also you will need to download "plink".

3 files:

1. VM_List.txt - a list of the machine names (case sensitive)
2. Step1.cmd
3. Step2.cmd

Step1.cmd: replace [] with your own data
==========================
echo off
set user=[user]
set password=[password]
set server=[server ip]
del log_Coalesce.txt /q
for /f %%A in (vm_list.txt) do (step2.cmd %%A >>log_Coalesce.txt)
==========================

Step2.cmd:
==========================
title ***** Working on %1 *****
echo ***** Start working on %1 *****
echo.echo Start at:
echo %date% - %time%
set vm_uuid=
"C:\Program Files\Citrix\XenCenter\xe.exe" -s %server% -u %user% -pw %Password% vm-list name-label="%1" --minimal > vm_uuid.txt
set /p vm_uuid=

plink -ssh %server% -l %user% -pw %password% coalesce-leaf -u %vm_uuid%
echo.
echo %date% - %time%
echo ***** End working on %1 *****
echo.
