Detach old ESXi installation devices

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… Read More »

Multiple service vROPs dashboard

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… Read More »

vRealise Log Insight and Orchestrator

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… Read More »

SCOM 2012 Hello World !

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… Read More »

The monitor_control.restrict_backdoor setting

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… Read More »
