How to Increase VCSA External PSC Disk Space in vSphere 6

The vCenter Server Appliance 6.0 uses the Linux Logical Volume Management (LVM) that allows you to dynamically increase the disk size of the vCenter Server disks. For the vCenter server itself the process to increase the capacity is well documented in KB2126276. When you have an external Platform Services Controller, the tool mentioned in the KB is missing. You can’t use “vpxd_servicecfg storage lvm autogrow” to increase the space automatically so you have to do it manually.

This post explains how to increase the disk space for an external platform service controller.

VCSA6 Bash and SSH Key Authentication

The Linux Version of the vCenter Server is not new anymore but with vSphere 6.0 the vCenter Server Appliance (VCSA) has overtaken the Windows Version in many aspects. The completely rewritten linked mode removes the need for a Windows-based vCenter and the scalability of both appliances are identical.

VCSA6 is delivered as appliance based on openSUSE. Nevertheless its a Linux, VMware want’s you to use the GUI. Unless you are in a testing environment I would highly recommend to limit shell usage to the following usage scenarios:

  • During Service Requests under advice of VMware GSS
  • For advanced troubleshooting
  • When required for complex deployments (eg. PSC 6.0 High Availability)

How to get “Use Windows session” Checkbox to work in VCSA6

You’ve just installed vSphere 6 vCenter Server Appliance (VCSA) and want to use the “Use Windows session authentication/credentials” checkbox like you know it from the vCenter Server running on a Windows Server?

You’ve already added an Active Directory as Identity source, and you can login with AD users, but the “Use Windows session authentication/credentials” still does not work?

You see the following error messages in the vSphere Client:
Windows session credentials cannot be used to log into this server.

Or in the vSphere Web Client (If the checkbox is greyed out, install the Client Integration Plugin from the bottom of the login page):
Incorrect username/password

This post explains how to get the “Use Windows session” checkbox to work

How to Join AD Domain in vCenter Server Appliance 6.0 (vCSA)

In vSphere 6.0 the vCenter Server Appliance (vCSA) has been changed a lot.

VMware vCenter Server Appliance 6.0 (vCSA) Enhancements

vCenter Server Virtual Appliance (vCSA) is still very rare in a production environment.

VMware vCenter Server Appliance 6.0 does now support up to 1000 ESXi Hosts and 10.000 Virtual Machines with the embedded Postgres database. I hope i can deploy more vCenter Linux Appliances in the future. Read more »

Failed to connect to VMware Lookup Service during Web Client Login

Howto Install Additional Software in VCSA 5

The vCenter Server Appliance (VCSA) becomes an alternative to the Windows-based vCenter more and more. There are several reasons to install additional software in the VCSA. When you want to implement additional services like DNS for your lab, or you want to monitor the Appliance via Nagios or SNMP, you need additional packages. The Appliance is based on SuSE Linux Enterprise Server 11, so you can use YaST to install packages. In this post I am going to show how to configure the vCenter Server Appliance to enable the installation of additional packages.
