VMware and other datacenter technologies
When clearing up host storage, you might sometimes encounter an error when you come to detach a device. The cause of this can be an old ESXi installation and you’ll need to erase the ESXi partitions in order to detach old ESXi installation devices. The typical use case for this is reclaiming SAN boot LUNs …
vRealize Orchestrator can communicate directly with the vCenter Server(s) that it is connected to, but uses the old SOAP API. However, with the advent of the REST API for vSphere, some things are easier (for example, tagging) and only possible to handle outside of the builtin abilities. In this post I will look at how …
aving worked with vRealize Operations Manager (vROPS) for a little while now, one of my aims was to enable end-users, i.e. application support teams and VM owners, the ability to log in and see a dashboard of all the VMs that are related to their service. Setting up a dashboard for each service seemed relatively …
I’m a big fan of the vRealize suite as it really adds value to a vSphere deployment. In relation to this post, LogInsight is a great tool for providing log analysis and Orchestrator manages workflows to automate and orchestrate most/all of the infrastructure. A series of posts on vmware.com – “Self Healing Datacenter” – have …
When working with block storage we occasionally need to remove a storage device from the hosts it is connected to. When using the Web Client we can detach devices on a per-host basis, but there is nothing to detach from all its attached hosts. What we do have is a helpful KB article on how …
Quick snippet on how to find the name of a service profile given the MAC address. I found this useful as when troubleshooting ESXi locks, the MAC address of the locking host is shown and sadly not the name. Once I had the name I was able to continue debugging my problem 🙂 Get-UCSCentralServiceProfile | …
This is the second part in an ongoing series looking at using the vSphere REST API and C++ with the cpp rest sdk (formerly known as “Casablanca”). In the first part we authenticated against SSO and got some information from the vCenter. In this part we are going to refine our methods so that we …
One of the main challenges in every (non-small) place I’ve worked is keeping VMware Tools updated, and with Change Management processes this becomes a little bit more complicated. There is a setting on each VM to upgrade Tools when the VM is booted and this is a good way to keep Tools updated on those …
I’ve been investigating how to connect to SCOM 2012 through code in order to extract information, and I thought a good first task (therefore a SCOM 2012 Hello World if you will ;)) would be to retrieve the current alerts. I couldn’t find any examples on how to do this, so after some searching came up …
The monitor_control.restrict_backdoor advanced setting is a strange one that I’ve encountered recently. It was set on a VM that had been (allegedly) security hardened, and researching this setting in a search engine indicated that this was to prevent the backdoor port from being accessed from anything other than ring 0 (source: https://communities.vmware.com/thread/464535). Most of the search results …
