Every x years ssl certificates need to be renew for the vSphere infrastructure. So in order to do this I needed a way to validate SSL expiration date. Well the thing is I don’t know an automated way of doing this. I started by look around google to see if there wasn’t a smart guy who had already done something like this and it turns out there is, so please put your hands together for Vadims Podans and is blog post Test remote web server SSL certificate. With credit due, I’ll continue with my small contribution. How to validate SSL expiration date What Vadims have […]

Been some time since the last blog post and I apologize for that, but it only because off happy circumstances, I became a father, for the second time to a healthy boy 🙂 So I have had some time off to be with my family. Well with that sorted lets move on to the topic of the day. Doing COW math Hope you have been doing your VMware COWs math… And here I’m of course talking about copy on write snapshots. Some time ago now got a few service request stating the some services were down for some VMs (50+). There were nothing obvious wrong, […]
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(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 […]
I’ve been running Log insight for some time now, first as part of the beta and then continued after it became GA, the last upgrade to 1.5 GA was a real pleaser. This tool has fast become one of my favorite VMware products, the insight you get into your environment is astonishing. This is the first tool I login to every morgning, way before vSphere client, vCops or even mail. 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, […]
Log insight – vCOPS Content Pack Log insight’s vCOPS Content Pack was released together with vCops 5.8, this content pack lets you get the same great insight into your vCops environment as log insight provides for your vSphere environment. There are three tasks to setting up vCops content pack for vCenter Log insight. Downloading and installing the content pack. Setting up vCops to syslog to Log insight.

(and if you haven’t downloaded the rpm file, now […]
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 […]
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.
Get-Cluster ClusterName | Get-VM | Get-VMResourceConfiguration | Set-VMResourceConfiguration -CpuLimitMhz $null -CpuReservationMhz 0 -CpuSharesLevel
"Normal" -MemLimitMB $null -MemReservationMB 0 -MemSharesLevel "Normal"
