Resurrect SRM Protection Groups
Use case: Some operational error or an environmental change has left all your protection Groups in an error state. All the VMs under the protection Groups have IP customizations defined using the vSphere UI. Therefore, a CSV file for dripcustomizer is not available. drIpReporter and XmlToCsv to rescue: Most versions of SRM ship with a handy tool called drIpreporter. This tool can generate a XML file for all your protection group settings including IP customization specifications. While most other configurations are quite straight forward to recreate IP customization can be a operational nightmare XmlToCsv can help you to create a CSV file from the output XML generated using drIpreporter . This csv file can be used with dripcustomizer after little modification. Feel free to check the code at https://github.com/akshaykalia-chd/XmlToCsv Modifications needed to csv file:
- VM ID: This filed need to be updated with the ID reported by dripcustomizer for the ...
Install and Configure a resilient network @Home!
A few weeks ago I posted a blog with a network design that can help you achieve better connectivity at your home. In this blog we will discuss the Installation and configuration of various devices use in that design. High Level Network Design Installation and configuration Step1: Reset all your devices to factory defaults The devices can be reset to factory defaults using the reset button. The location of this button varies for device and vendor. Make sure to keep a note of DSL and PPOE credentials before following this step Step2: Find the default IPs You can find the default IP of the device by reading the device label usually located behind the device. A few examples below
Building a resilient Work from Home network!
In last one year we have all battled the largest pandemic ever witnessed by the human race. One positive outcome of this pandemic is Work from Home culture. Not only do we know it works, but we also have KPIs and Matrices to prove that it is productive. The organizations around the world are talking about implementing some form of work from home strategy. The question is, Is your home ready for the future of work? Today in this blog I will cover a Home network that provides low-cost resilient Internet access High Level Network Design Investments Looking at the above diagram you might be thinking what should I buy to implement! To implement the above network we need following devices
- FTH Modem
- ADSL Modem
- 4g/5g Modem
- WAN Load Balancer
- Wifi Router

vMware vSphere Bitfusion – Cluster Destroy and Downsizing Demo
Till now I have covered: In this blog we will cover the Cluster Downsizing and destroy operations with a demo The steps to Downsize a VMware vSphere Bitfusion cluster are as under:
- Delete a node using VMware vSphere Bitfusion plugin
- Check the output of “nodetool status” on one of the remaining nodes
- Once the Node deleted using the vSphere Bitfusion plugin is no longer present in the output of “nodetool status”
- Power Off the Node
- Delete from disk or inventory (Optional)
- If you keep the VM, do not power it on without adding it back to cluster
- An accidental power on of this VM may overwrite the VMware vSphere Bitfusion plugin
- Repeat Step 1 to Step 3 for every node you would like to delete
