VMware vSphere 6.5: Migration from Windows vCenter to vCenter Server Appliance

VMware vSphere 6.5: Migration from Windows vCenter to vCenter Server Appliance

Following on from my previous posts (What’s New in vSphere 6.5 and VMware VCSA 6.5: Installation & Configuration), a major area for discussion (and excitement) is the VMware Migration Assistant which, should you wish, is able to easily migrate you away from the Windows-based vCenter Server to the Linux-based vCenter Server Appliance (VCSA).

There are pros and cons to the vCenter appliance of course, as well as a healthy number of supporters in each camp, but if you fancy shaving some licensing costs (Windows Server and SQL Server), would like to enjoy a faster vSphere experience (since 6.0), or would just like to be able to take a quick backup of vCenter without having to either snapshot both Windows and SQL Servers elements, or by utilising your backup product of choice to take a full image of your environment, you might just want to take VCSA for a spin.

This post will detail the migration process of a Windows-based vCenter 6.0.0 U2 to vCenter Server Appliance 6.5. Continue reading

VMware vCNS 5.5.4 to NSX 6.2.5 Upgrade

VMware vCNS 5.5.4 to NSX 6.2.5 Upgrade

I’m a fan of upgrades that ‘just work’, but rarely do they run without a few unforeseens jumping out at you. Reading the VMware Upgrading VMware vCNS 5.5.x to NSX 6.2.x (2144620), I was surprised to see just five upgrade areas. Five? Really?? As this is a business critical system (and one with the potential of being able to turn a long day into an even longer day were things to go awry), I was a little sceptical, however, the vCNS to NSX upgrade process really is that easy.

A great new range of informational overviews is available via the VMware Product Walkthroughs website. Covering a range of product overviews (from vSphere 6.5vRealize Network Insight, and more), to the specifics of vSphere 6.5 Encrypted vMotionNSX VXLAN Configuration, Virtual SAN Fault Domains. Great on so many levels, enabling us to up-skill and dry-run new products, demonstrate solutions to management and technical teams, etc. Continue reading

VMware vSphere: Locked Disks, Snapshot Consolidation Errors, and ‘msg.fileio.lock’

VMware vSphere: Locked Disks, Snapshot Consolidation Errors, and ‘msg.fileio.lock’

A reoccurring issue this one, and usually due to a failed backup. In my case, this was due to a failure of a Veeam Backup & Replication disk backup job which had, effectively, failed to remove it’s delta disks following a backup run. As a result, a number of virtual machines reported disk consolidation alerts and, due to the locked vmdks, I was unable to consolidate the snapshots or Storage vMotion the VM to a different datastore. A larger and slightly more pressing concern that arose (due to the size and amount of delta disks being held) meant the underlying datastore had blown it’s capacity, taking a number of VMs offline.

So, how do we identify a) the locked file, b) the source of the lock, and c) resolve the locked vmdks and consolidate the disks?

VMware vCenter Server Appliance 6.5: Installation & Configuration

VMware vCenter Server Appliance 6.5: Installation & Configuration

Following the general release of VMware vSphere 6.5 last month (see my What’s New in VMware vSphere 6.5 post), I’ll be covering a number of technical run-throughs already in discussion throughout the virtual infrastructure community.

We’ll be starting with a fresh installation of the new and highly improved vCenter Server Appliance (VCSA), followed by a migration from the Windows-based vCenter Server 6.0; the latter task made all the easier thanks to the vSphere Migration Assistant. More on this to come. Lastly, I’ll be looking at a fresh installation of the Windows-based product, however, the experience throughout all of these installation/migration scenarios has been vastly improved.

Microsoft Exchange Server 2013 – Installation & Configuration

Microsoft Exchange Server 2013 – Installation & Configuration

One of the major upcoming projects this year will see the upgrade and possible redesign of our Exchange environment, and this will mean upgrading our current Exchange 2010 solution to Exchange 2013. With this comes a number of differences (the management GUI to name just one), and I aim to capture my initial thoughts of the product in this and upcoming posts. In future posts we’ll cover various topics including the creation of database availability groups (DAGs), load balancing, and general all round resilient goodness! Continue reading
