This article will cover how to update existing NVMe-TCP target controller connections keep alive value. Unfortunately you can not just update the active controller connection and have to disconnect and then reconnect that controller with the updated values. This really applies for NVMe-TCP controller connections created in vSphere 8.0 U2 or earlier. The default keep […]

My FlashArray REST API 2.x Authentication Journey
My journey in understanding FlashArray REST API 2.x Authentication was full of bumps, confusion and frustration. Here is how I progressed in figuring out how to authenticate with Oauth2 to issue REST API 2.14 requests.
New REST API’s for vVols Objects in Pure Storage FlashArray REST API 2.14
There are some new REST API’s for vVols objects in Pure Storage’s FlashArray REST API 2.14! Specifically operations for virtual-machines and virtual-machine-snapshots. I won’t lie, the hardest part for me was figuring out how to use REST 2.0 with the FlashArray. The change from using standard authentication to using Oauth2 for REST 2.0 took some time. I had a lot of fun playing around and learning about them and want to share that process!
How to Enable CBRC and Digest for a Data vVol in vSphere 7.0
Recently I was working through an issue that was reported by one of our Partners. I wanted to see if I could reproduce the issue and if it may have been an issue with vVols with Pure. What was the issue you ask? Essentially there was an issue reported that inconsistent behavior was seen with […]
How to Refresh VASA Certificates with vSphere 7.0
When VMware released vSphere 7.0 they disabled the ability to refresh certificates for VASA Providers in the vCenter UI. When logging into vCenter and trying to manage the certificate for the storage providers you will see that the refresh button is greyed out. Whether this option being disabled was done inadvertently or on purpose I’m […]
How to Create SOAP Trace Logs to Troubleshoot PowerCLI Errors
Ugh! That’s my first reaction to seeing a failure from PowerCLI when I’m running through a workflow with PowerShell, however, I recently learned the process of creating a SOAP trace log to better troubleshoot failures in PowerShell when using PowerCLI. Based off of prior experience, nine times out of ten the error messaging is not […]
FlashArray Replication, vVols and SRM 8.3 – Test Failover
VMware vSphere Virtual Volumes (vVols) and FlashArray based replication will now be supported with Site Recovery Manager (SRM) 8.3! Along with the ability to leverage the API calls for SPBM Failover and Reverse operations for vVols with PowerCLI or vRO, SRM will now support the SRM recovery workflows with vVols and array based replication.
vVol Troubleshooting – What to do with a Empty VP URL
One of the more common issues I have seen when getting started with vVols is when an ESXi hosts is unable to authenticate with the VASA Providers. There can be a few reasons for this happening, so I wanted to dig into some of those reasons, how to troubleshoot them and hopefully fix them.
Too Many Authentication Failures when trying to ssh to SRM
With the release of the Photon based SRM server there were bound to be some issues pop up. One of these has to do with the sshd service and configuration. What’s the issue? Specifically the issue is with the MaxAuthTries option in the sshd.config, in which I found that it’s commented out. What does that […]
Why does vCenter report ‘lost access to volume’ during a non-disruptive Storage Array event?
A question that I see asked in forums, slack channels, direct messages, etc, is why I see that access to storage was lost during events that are viewed as non-disruptive…since you know, lost access to volumes seems to be a disruptive event. By a non-disruptive event I am talking about an HBA SFP or cable […]
