Continuing my recent work on learning vRealize Orchestrator and ran into some funkiness with the “Invoke REST host” workflow, that I wanted to write down so I don’t forget how I fixed/worked around it (which I suppose is the impetus for basically every post I do). Anyways, I am working on a REST-based package for the FlashArray and I was using that workflow and had some trouble. Basically, any REST call I made through it to a REST host seemed to fail.
Starting to mess around with vRealize Orchestrator and just deployed the 6.0.3 vRO appliance. A few gotchas, many of which are well denoted by other blog posts:
- DNS, DNS, DNS!! Pre-configure everything and make sure names are correct
- Certificates, make sure they are accurate
One of the first issues I ran into was registering it with my SSO. My setup has two vCenters with two separate but federated Platform Services Controllers. I wanted to authenticate my vRO instance with SSO, not my Active Directory to keep user management a bit more central to VMware. Ran into some fun gotchas. (more…)
Somewhat surprisingly I have been getting a fair amount of questions in the past few months concerning VMware vCenter Site Recovery Manager and Raw Device Mappings (RDMs) and using this with Pure Storage. Common question is whether or not we support this (we do) but more commonly it is about how it works. There is a bit of a misunderstanding on how they differ or do not differ from VMFS management in SRM. So figured I would put a post out to explain this. Old topic somewhat, but worth reviewing for those newer SRM customers. Plus, I haven’t found a whole lot of on-point posts anywhere, so why not?
That time of the year again, VMworld Europe! My second one with Pure Storage and my 5th VMworld Europe (just finished my 8th VMworld US!). I am hoping I get to actually attend some sessions this time, was far too busy at the US show, but most likely won’t this time around either. Anyways, what’s in store for Pure Storage in Barcelona?

Quick update. I have posted a new version of the PowerCLI UNMAP script that I maintain. I usually do not put a blog post out every time I update it, but there were enough changes here I think it was worth a quick note.
A question came up on our community about a Chrome extension called Advanced REST Client and I had never used it before, so I decided to check it out. Install it here. It will add an extension that allows you to make REST calls to, well whatever from your Chrome browser.
Of course there are a billion ways to do this (I traditionally have just used Invoke-RestMethod in PowerShell) but this is another one for your tool arsenal . A quick and easy way to pull REST information from the FlashArray without having to learn another tool like PowerShell to do it.
One of the things in vSphere 6.0 that I really wanted to look at was the Instant Clone functionality that was included in the release. Instant Clone (AKA Project Fargo AKA VMFork) is the ability to essentially instantly create new virtual machines that are identical copies of a running parent VM by sharing the current memory and virtual disk files of that parent. The “forked” VMs are basically resumed copies of a stunned parent and the disk write/memory changes are committed down to delta VMDKs or delta memory pages while the children continue to read from any unchanged data in the parent VMDKs.
Plenty of other people have gone into more detail on this and the architecture, so instead of me re-writing all of this check out this post from Duncan Epping:
Or Google it.
Cool stuff. So I plan on doing a few different posts on this, tons of thoughts how this could be used, this first post though will focus on just simply setting it up. (more…)
Quick post here. I recently updated my environment to vCenter 6.0 Update 1 and VMware Site Recovery Manager 6.1 and after my first attempted test failover (and subsequent ones) the test would always fail when it tried to power on the virtual machines. Some powered-on and some didn’t. The following errors appeared for about half of my VMs:
I was working on rebuilding my VMware lab environment today and for simplicity’s sake decided to leverage two external Platform Services Controllers (PSC), one for each of my vCenter environments (I need two because I am setting up Site Recovery Manager) in a federated manner. Akin to the previous term of “linked mode” If you are not familiar with PSC which was added in vSphere 6.0, check out this KB. I went with the 3rd deployment model illustrated in this KB. (more…)
