vCenter lost DVS configuration – Fixing the hosts

Networking, VMware, , , , ,

So I hit an interesting issue whilst performing a VMware upgrade from 4.0 to 5.5. There was a legacy issue left where vCenter had lost its knowledge/configuration of the DVS Setup.

Im not entirely sure what happened or when, as it was an existing environment, I only know I had to fix it. (Many thanks to the help from my good friend over at www.vmtechy.com for refreshing me on the ESX 4.0 command line to fix this).

The Symptoms

Within the vCenter Client, on the host summary tabs.

Installing VMware Horizon View Composer fails with Error 1920

The issue

So today I was installing VMware Horizon View Composer on my Server 2012 R2 vCenter machine, where the SQL database is also local to this machine.

And I came across the below error,

"Error 1920, Service VMware Horizon View Composer (svid) failed to start. Verify that you have sufficient privileges to start the system service"

Which I something I’ve dealt with before, but I must admit I forgot the fix, and was looking into the following area’s;

  • Check account is Administrator and has “Log on as a Service” right
  • Check there is no pending restarts
  • Check ODBC is set up correctly and gives a successful message when testing

Back to the Future – Configure ESX 4.0 iSCSI Multipathing

Networking, VMware, , , , , , , ,

So I’m in the middle of an upgrade of environment that has;

  • 2 x Hosts on ESX 4.0
  • SAN using SAS connections to Hosts
  • No resources available for failover and testing
  • Limited network ports

I’m installing;

  • 3 x Hosts on ESXi 5.5
  • Nimble SAN – iSCSI

So to move all the virtual machines from the SAS SAN to the Nimble, I need to move the VM’s whilst turned on,

I’ve setup the iSCSI networking on the ESX host,

  • Creating VMKernal ports with IP addresses,
  • Mapping a VMNIC to each VMKernel directly
  • Setting MTU size to 9000

Veeam: High Level End user case study, from an engineer’s perspective

Uncategorized, , ,

Sometimes we get so bogged down into the technical details, we forget that some people just want to know about a product and how it’s used, not how to configure it and the advance settings.

This blog post was first wrote for my employers blog by me, but I think it’s a perfect High Level post detailing a customer and how the product met their requirements.

The Company

Working in the financial sector, the company has around 200 on-site employees, projecting to expand up to 300 with a recruitment drive they are planning. After having a new VMware infrastructure implemented and upgrading their Microsoft Servers to the latest and greatest, the backup solution was the next on the upgrade list.
