Veeam Backup & Replication 9.5 Update 3a

In this article we’ll cover the simple process of applying the latest Veeam Backup & Replication 9.5 update, Update 3a (released July 2nd 2018), however, I’d first like to cover what’s new in Update 3a, and why you might like to upgrade.

Update 3a brings support for a host of new VMware and Microsoft features, as well as a substantial number of enhancements. With VMware vSphere 6.5 U2 and 6.7 now well into GA, the release of Update 3a is something most of us have been craving in order to obtain that final green light to upgrade our vSphere environments. From the Veeam Release Notes for Veeam Backup & Replication 9.5 Update 3a the enhancements and newly supported features are detailed below. Continue reading

VMware vRealize Log Insight – End of Availability

Yesterday (Monday 16th July 2018) VMware announced the End of Availability for vRealize Log Insight for vCenter. This enabled all vCenter Server licensees to enjoy a cool 25 OSI (Operating System Instance) usage. Sadly, the current version of vRealize Log Insight (6.4.x) will be the last version to support vRealize Log Insight for vCenter and, as such, the next release will not accept vCenter Server license keys during activation. End of General Support for vRealize Log Insight for vCenter will run until 23rd August 2019.

Please note, vRealize Log Insight standalone (part of the vRealize and vCloud Suites), Log Insight for NSX, and Log Insight for VMware Cloud Foundation will not be affected.

For more information, please view the recent VMware Blog article and Knowledgebase Article KB55980. Likewise, please also check out the VMware Lifecycle Product Matrix.

Veeam Explorer for Microsoft Exchange – Configuring Application Impersonation

To restore an Exchange mailbox/folder/item via the Veeam Explorer for Exchange, the account connecting to the Exchange server will require Full Access to the mailbox in question. To perform such a restore (without having to give your entire backup admin teams Full Access to every mailbox in your estate), we will cover the process of granting Application Impersonation to your administrative staff. This procedure applies to both on premise Exchange and Office 365 and can be easily implemented via a few simple Exchange Management Shell commands.

Reclaim VMFS Deleted Blocks via VAAI UNMAP

Since the release of vSphere 5.5 back in September 2013 we have been able to utilise ESXCLI to manually reclaim deleted blocks from VMFS datastores. Essentially, by using the VAAI UNMAP primitive, we can reclaim previously used blocks by releasing them back to the storage array, allowing them to be re-utilised by other devices/virtual machines. It wasn’t until the release of vSphere 6.5 in November 2016 that the much sought-after automation of disk space reclamation was announced with the availability of VMFS 6. More on VMFS 6 and automated reclamation in a future post.

In this article we will cover the manual process of reclaiming deleted blocks from a VMFS 5 (or earlier) file system via a esxcli UNMAP call. Continue reading

London VMUG – 14th June 2018

Thursday 14th June saw the latest London VMUG take place at Tech UK, London, with the User Group marking it’s third outing for 2018 in just six months! Rarely does any event see such heavy hitters as Duncan Epping, Frank Denneman, and Niels Hagoort in one place, but today, we got to see all three in attendance. Add to that line-up further awesomeness in the form of  vCommunity member, Chris Porter, and this was one truly great London VMUG indeed! I’ve been to a number of VMUGs around the UK, however, this was to be my first time joining the London gang.

VMware NSX for vSphere 6.4.1 – One Click Upgrade

With the release of VMware NSX for vSphere 6.4.1 on May 24th 2018, interoperability/compatibility between VMware vSphere 6.7 and NSX was achieved. In addition to this, a number of nice new features were also included in the update.

In this article we will upgrade a 6.4.0 (build 7564187) lab environment to 6.4.1 (build 8599035) utilising the One Click upgrade process. Continue reading

Editing Protected VMs in vSphere

By design, there are certain virtual machines and/or appliances within vSphere which are protected to prevent editing (this can include NSX Controllers, Edges, Logical Routers, etc.) In a live/production environment, you’d not normally care about editing these appliances, however, in a lab environment (especially one where resource is tight), reducing memory and/or CPU allocation can help a lot. As such, this article will cover the process of removing the lock on protected VM in vSphere, in order to enable editing.

The scenario: a customer needs to reduce the resource allocation of an NSX Controller, however, due to the VM in question being protected/locked, editing the VM’s resources is not possible via UI or PowerCLI.

The process of removing this lock is quick and easy, however, we first need to identify the virtual machine’s Managed Object Reference (moRef ID). Please note, VMware do not support or recommend this procedure in any way.  As such, this procedure should not be implemented in a production environment.

VMware vRealize Log Insight: Part 2 – VMware NSX Integration via Content Packs

In Part 1 of this series we covered the simple installation and configuration of VMware vRealize Log Insight. In Part 2 we will cover how we can further configure and customise Log Insight via Content Packs in order to leverage further logging capabilities.

As mentioned in Part 1, one of the caveats of utilising this ‘free’ version of Log Insight (or more aptly, the 25 OSI license available to all vCenter Server licensees), is the ability to use VMware-only Content Packs. This is far from a bad thing and, as a result, enables us to integrate with other VMware products including NSX, Horizon, SRM, etc. In this article we will focus on the former product.

NSX Manager – Replacing the SSL Certificate

Applying a new SSL certificate to your NSX Manager really couldn’t be easier and, as the NSX Manager is part of a wider, security orientated product, we might as well do things properly and apply one!

First of all, and if already not in place, we’ll need to create a new Microsoft CA Template for SSL in vSphere. To do this, please take a look at VMware KB article 2112009. The procedure itself is a simple one, and I make reference below to a vSphere 6.x SSL certificate template, so it’s worth pointing out. This template was created using the aforementioned VMware KB.

To replace the NSX Manager SSL certificate, and to cert against your CA of choice, simply follow the below process. Continue reading

VMware vRealize Log Insight: Part 1 – Install & Configuration

If, like most of us, you forward vCenter and ESXi host Syslog data to centralised Syslog targets (and if you don’t, then I’d advise you do), then you’ll be pleased to hear that (as long as you have a valid vCenter Server license) you’ll be able to utilise the power of VMware vRealize Log Insight to interrogate this data.

This article will be the first in a two part VMware vRealize Log Insight series, the first of which will detail the simple installation and configuration process, with the second article focusing on advanced configuration and integration with VMware NSX via vRealize Log Insight Content Packs (vRealize Log Insight add-ins enabling further integration with both VMware and 3rd party products).
