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).

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

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.

Integrating Active Directory with VMware vSphere SSO

One item I see mentioned fairly often, either in relation to personal labs or production environments, is the integration of vSphere SSO with Active Directory. Configuring vSphere’s SSO/AD integration via LDAP is a simple process, more so thanks to vSphere 6.5. Continue reading
