EHC 4.1: ESXi Host Migration Process (vCenter Host Migration with ViPR Export Groups)

This procedure details the steps to execute in order to remove an ESXi host from a source ViPR Export Group and add to an existing target Export Group.

Note: this procedure applies to ViPR 3.0 and below, ViPR 3.5 introduces a more automated procedure which I intend to cover in a future post.

Host Removal – remove ESXi Host from a ViPR Export Group

Please ensure the current ViPR configuration is in a known good state before proceeding and that the ViPR database is edited where required to bring it in synch with the live environment. Contact DellEMC support to assist with any ViPR database remediations required.

Note: Ensure the version of SMI-S complies with the EHC ESSM stated version.

The following steps detail the procedure for removing a host from a vSphere ESXi cluster in vCenter and utilizing the ViPR CLI to remove the same host from the cluster Export Group. Continue reading

V(x)Block – AMP VUM & SQL Active Directory Integration

When a VxBlock is shipped from the factory all Windows & SQL user/db accounts are setup as local accounts, due to obvious reasons (customer AD does not exist in factory!). This post details the steps to integrate a VUM VM & SQL with Active Directory and change the local WIN&SQL accounts to AD accounts, along with modifying the SQL DB permissions to an assigned AD account.

At a high level these are the prerequisite steps:

– Change DNS values on the Windows VUM VM (if different from LCS stated values).
– Join Windows VUM VM to AD.
– Reboot VUM VM.
– Snapshot VUM VM (precautionary step).
– Add domain\svc_vum to local admin group of the VUM VM.

Use the following procedure to configure domain service accounts for the VUM Server and services & configure SQL Server access permissions on a VxBlock based EHC deployment:

vRealize Automation 7.1 Wizard Install – vCenter Agent Name not aligned with IaaS Host

Looks like there maybe a bug in the vRA 7.1 wizard deployment. I’m running vRA version  7.1 build 4270058 and Windows 2012 R2 build 9600.

Even though we configured the vCenter endpoint name as cloudvc01 during the vRealize Automation wizard based install, the IaaS Agent server was displaying the vCenter agent name using the FQDN cloudvc01.ppsilver.lab.local (screen captures below):

Wizard input – ‘Agents’:

vRealize Automation 7.1 – Installation (Part 1)

This post will provide a step-by-step walk through installation of vRA 7.1, utilising the vRA wizard based install and configuration utility.

This example focuses on the ‘Enterprise Install’ for a distributed, highly-available vRA instance, using the wizard-driven walk through for the installation. The wizard helps to drive such tasks as importing the user generated certificates, creates your vRA SQL database and automatically fixes any issues on the IaaS Windows machines encountered during validation, for example removing MS patches that impede the install or fix IIS related configurations.

This post does not cover pre-requisite tasks such as:

  • Deploying the vRA appliance.
  • Provisioning & joining domain for the required Windows 2012r2 servers detailed on the infrastructure list below, SQL|Web|DEM|Agent machines.
  • SQL server installation.
  • DNS entries for all the components including virtual IP addresses.
  • Ensuring NTP & time is correct across all related components.
  • IaaS associated user accounts.
