Connectivity Test For VLAN/Port Groups

ruckers05 — Tue, 05 May 2009 16:46:32 GMT

Hello there,

I was wondering if anyone has a soloution to my problem, to cut a long story short i want something that would check connectivity to each VLAN from each ESX host.
I manage a 24 host VMware ESX cluster based on IBM LS42 blade servers across 5 racks and 9 chassis and these are all linked together with cisco switches.

The problem i have is the network sometimes experiences failures which mean chassis or rack switches have issues with some of the VLAN's.
At the moment im migrating a vm connected to each vlan between each host / Chassis to ensure it can speak to the Default Gateway on that VLAN.

Is there a way doing this a bit less manually? im prepared to put the time into scripting something but im unsure how best to approach it (or if there is something there already?)

I just need each VLAN's DG pinging from each host... ideas?

Thank you!

Ed

Script to find RDMs

hi1280 — Tue, 03 Nov 2009 02:39:17 GMT

This is my 1st offical communities post. Hopefully I'm following all the rules. I've followed both community posts that copied below. The rdm.sh posted by lamw (also attached below) at http://engineering.ucsb.edu/~duonglt/vmware/ is not producing accurate results for me. It does report back some of my RDM's, but not all. If it's something I'm doing wrong please don't fault lamw, it could just be my environment, please test his script as it did return some results for me. Has anyone (other then a 3rd party app) found a way to script an accurate report on all RDM's? Again below are the links that led me to the rdm.sh script. I'm running ESX 3.5 U4 on a 10 node ESX cluster over FC.

Need help to edit sudoers using script

SBC350 — Mon, 02 Nov 2009 20:16:42 GMT

Hi, im using a kickstart script to automate my ESX installation.

There is a line in the script used to uncomment 1 line in sudoers but it uncomment 2 lines concerning wheel.

Here is the script: sed -i 's/# %wheel/%wheel/g' /etc/sudoers

Here is the part I want to edit in sudoers "# %wheel ALL=(ALL) ALL":

"# Uncomment to allow people in group wheel to run all commands
"# %wheel ALL=(ALL) ALL

"# Same thing without a password
"# %wheel ALL=(ALL) NOPASSWD: ALL

Thank you

Single-host reboot script?

JaySMX — Fri, 30 Oct 2009 13:47:59 GMT

I have a single ESX host with a couple VMs running on it that I want to schedule a reboot for. I need to have it cleanly shutdown the VMs, reboot once the VMs are down, then power the VMs back on once the ESX host is back up. What's the easiest way to do this?

I can schedule all this with cron jobs on the host and scheduled tasks within VC, but at least one of the VMs takes a while to shutdown sometimes and I want to ensure it shutsdown cleanly. I don't want to just guestimate the times if I can avoid it. Anyone know of a way to build some logic into this so the host will only reboot once all VMs are powered off?

View Desktop Provisioning Error - Disabled

elkhornps — Mon, 19 Oct 2009 19:41:49 GMT

We have been using view for about 2 months since the start of school in a few areas. One thing that has happened 2 or 3 times before today is that our automated pool would encounter an error and disable provisioning. When this happened so far enabling provisioning again picks up whever everything left off and no further issues. The negative part about these issues is that I don't find out till about an hour after the error occurs when there are no more available desktops. Then it's a mad rush to get enable the pool and get things going again. I created a script that queries the view ADAM database and if the pool is disabled, sends me an email and a txt message so that I can go check things out before anyone notices an issue. Hope this helps someone. I plan to turn this into a vb.net service at some point, but right now a quick and dirty vbs script that I can run as a scheduled task is working great.

Configure Switching for ESX host based on .CSV

aerodevil — Tue, 06 Oct 2009 17:32:12 GMT

A couple of weeks ago I was in need to configure several new ESX servers with multiple NICs, vSwitches, and VLANs. Since I'm not one to do the same thing over and over again I turned to scripting. To further complicate things I wanted to allow the same script to create vSwitches, configure vMotion switch, add port groups, and create NIC Teams all from a prepopulated .CSV file. I'm doing this primarily so that all configuration could be done before the server arrived and so that I could create "Switch Profiles" when I add new hosts to clusters.

In the end I developed a script that reads from a .CSV file and then creates the desired switching. The first column tells the script what type of addition it is and the script processes the information for that object accordingly. I've noticed a few others have been posting recently about scripts on setting up portgroups, etc. and thought it was time to no longer keep this to myself (i.e. finally found the time to post). I too would like to also credit Hal Rottenburg's book Managing VMware Infrastructure with Windows Powershell which was very helpful for this and many other scripting projects I will be posting soon. Mike Laverick's post linked below helped in configuring the vMotion switch.

I hope you find this helpful. It has been HUGE in my environment.

GhettoVCB script implementation question.

saldon — Wed, 16 Sep 2009 14:43:52 GMT

First, I'd like to thank WIlliam for his outstanding work on the various tools he has created.

Now I have a question concerning using the ghettoVCB srcipt in my environement. I have 4 ESX servers in a cluster. It appears that the script needs to be run on each individual ESX host to get a backup of all the various VM's I need to protect. The catch is, with vMotion and DRS, how do I know where each VM is currently being hosted so I can back it up?

The short answer is write a script to determine which VM's are actually running on a given host. Compare this list to a list of VM you know you want to back-up, and then dynamically create your list of VM's to back-up each time you run backups.

So has anyone written a script like this that they can share? I've searched the communities and I have not found one yet. I could go create my own but why re-invent the wheel?

Thanks.

Getting the DNS name servers from an existing virtual machine?

karnowski — Thu, 20 Aug 2009 14:13:50 GMT

I can set the DNS name servers successfully (by using the CustomizationGlobalIPSettings object), but how do I get the list of DNS name servers from an existing virtual machine through vSphere's web API? I'm trying to get the values of the "nameserver" lines in the /etc/resolv.conf file for a Linux VM.

"service mgmt-vmware restart" in a scripted install...

hharold — Thu, 28 May 2009 14:41:30 GMT

Hi,

as a lot of you propably do, I do a "service mgmt-vmware restart" in a scripted install.
I need this because I want to use vmware-vim-cmd ommands.

When the "service mgmt-vmware restart" is executed, the complete installation halts, and just sits there.
When I do a "service mgmt-vmware restart" manully from a SSH session, no problems.
When I do a "service mgmt-vmware restart" from a console session (HP iLOE) the problem become clearer.
During the restart the screen moves to the "logon to ESX server....press ALT-F1 etc " - screen

When I press ALT-F1 i re-enter my session again and see the result of the "service mgmt-vmware restart" command.
But this clearly kills my script as it cannot continue.

Anyone any ideas?

btw: ESX 3.5 U3

Thanks and kind regards,

Harold

ESX 3.5 & the elusive hponcfg

Chage — Thu, 30 Jul 2009 00:11:25 GMT

Hi All,

Our ESX environment is mostly a HP affair, running(typicall) ESX 3.5 Update 3. At the moment Ihave the unenviable task to turn on AD Integration on 200+ HP servers, with a significant portion of them being ESX Hosts. This is relatively painless for the windows standalone servers, where the hponcfg utility is available and I just feed it a scripted configuration. This does not seem to be the case with ESX.

I have read a number of posts about this, and all seem relatively "hacky", cobbling together various linux rpms, and hoping it will work.

Is there a silver bullet solution to installing hponcfg, or is it a case of HP dropping the ball on this one?

Automator Actions

etung — Wed, 03 Sep 2008 01:25:34 GMT

I've been toying with Automator recently, and came up with some actions for Fusion. Currently, the actions include:

List running virtual machines
List virtual machines in the Virtual Machine Library
Perform power operation on a list of virtual machines
- Power On
- Shut Down (soft)
- Power Off (hard)
- Reboot (soft)
- Reset (hard)
- Suspend
- Pause
- Unpause

Suggestions for more actions are welcome.

I will update this top post if and when I make updates so you don't have to search through the thread.

Nothing too exciting yet, this is mostly stuff you can trivially do with vmrun (pause/unpause is perhaps particularly interesting, since Fusion doesn't currently have a UI for this). For example, one useful combination would be to list all running VMs and pause them, and a matching action to list all running VMs and unpause them - this might be handy if you want to quickly devote computing power to some task but don't want to suspend.

The current version is 0.2008.09.02. To use, unzip and put the resulting actions in /Users/${USER}/Library/Automator/ or /Libarary/Automator/
