Maximum vDS ports per host

Posted 1 CommentPosted in Script

First of all its been awhile since my laste port and for that I apologize. Maximum vDS ports per host Some settings are just left default, maybe because it seems to be of no use/harm, maybe because it seems sufficient and some are just left default as the consequences of changing them are unknown. Well I guess this is just one of the problems where all of the above fit right in. You may know that there are some limitations of whats supported by different vSphere components – and this is were the problem in question comes to play. When you […]

Correcting Multi Path Policy

Posted Leave a commentPosted in Script, VMware

Correcting Multi Path Policy(MPP), is some thing i had to do recently – The story goes… The storage team had brought in a new storage array/vendor and started making datastores from that, now a few hundred datastores later, someone noticed that some path where highly utilized while others again was hardly used at all. So after looking into this, it was desisted to change the Multi Path Policy to RoundRobin as per the vendors recommendations and best practices. While making the script for this I noticed that some local disks were already set to RoundRobin where they were suppose to be […]

So how can that be… Hopefully what comes next will make you understand what I mean   Log Insight Snapshot Content Pack So I’ve had some time to work with Log insight, […]

Bulk create vSwitch networks

Posted Leave a commentPosted in Script

I blogged a bit about this in the Consolidating datacenters post. As part of moving a customers VM’s in to our datacenter, the network and storage was streched and host deployed in our datacenter was presented to the customeres vCenter, so that it was a simple (s)vMotion, that was all that was needed to move the VM’s from customer site to our datacenter. Simple, fast and effective. All this was only possible because the customer still used the standard vSwitch – As our datacenter uses the distributed virtual switch, I created this script in order to stadalize how network was created […]

Reset VM reservations and limits

Posted Leave a commentPosted in Script

I was moving a customers VM’s from their site via vMotion into our datacenter, and one of the problems you can run into is with reservations and limits. There may have been valid reasons for having limit and reservations, but they can also be the root of performance problems. As this was not the case with this customer, I created the one liner below in order to remove the reservation and limits.

 

vCops Forced password change

Posted Leave a commentPosted in Vcops, vRops

Short after vCops 5.8 was released I upgraded, all went smooth. But then the other day, I had to restart the appliance, after waiting a while and I was still not able to login to the web gui. I open up a console to the two VMs, only to see the both VMs were stuck at boot waiting for a password change. So I typed in the old password and a new one and shortly after vCops was up and running again.   Well as it turns out had I just read the release notes properly, I would have know […]

I was trying get some hardware info via CIM, the other day and ran into this error message:

After googling the error i found a lot of site pointing to this command –

  which needs to be run as admin. Only problem it doesn’t work on windows 7/2008+… As it turns out, it was for windows xp/2003 – So I starting looking for the same command for windows 7/2008+ and guess what I found one. Once again this needs to be run as admin in powershell this size can be changed as needed on some HP G7 […]

Batch rename of VMs

Posted 1 CommentPosted in Script

The other day a consultant came by my desk. He had a problem, the 400 VMs we just move from the customer site in to our datacenter; The backup jobs were failing for most of the VMs. He had looked into it and it turns out that Symantec Netbackup, which is what is used, is case sensitive and the VM names were all a mix of low, high and low and high cases. So the backup team had to recreate the backup jobs, but before they did that, the consultant asked if it wasn’t possible to rename all of the […]
