DellEMC EHC – ‘Onboarding A Local Cluster’ (Part 2)

The following two-part post details how to add an Enterprise Hybrid Cloud (EHC) vSphere Local Cluster, in EHC terms we refer to this cluster type as LC1S (Local Copy on One Site).

There are a number of prerequisites required in advance of running the Onboard Cluster workflow in EHC, namely:

  • Add a Site
  • Add a vCenter
  • Add a Hardware Island

Part 1 addresses the first two prerequisites (Add a Site, Add a vCenter):

The following Part 2 post details how to:

  • Add a Hardware Island
  • Run the Onboard Local Cluster workflow in EHC

Adding A Hardware Island

An EHC hardware island is a set of compute, network and storage resources belonging to one vCenter for example a hardware island may consist of  subset of resources on one VxBlock, a vCenter can accommodate multiple hardware islands. A hardware island can support multiple vSphere clusters. A ViPR vArray can only be associated with a single hardware island. For further information on the EHC hardware island please refer to the EHC Concepts & Architecture Guide.

Begin by logging into the EHC tenant portal as the system administrator with entitlements to the EHC Maintenance catalog items. Navigate to: Catalog -> EHC Configuration -> Hardware Island Maintenance:

DellEMC EHC – ViPR vPool Volume Migration

This post details the procedure and EHC validation steps to execute in order to move an EHC ViPR provisioned volume to a different ViPR virtual pool leveraging the ViPR Change Virtual Pool services.

High level steps that will need to be followed:

  • Create a new ViPR vPool with all identical properties except for one that you are changing (Best to use the duplicate button and then modify the copy).
  • Migrate ViPR Volume(s) to the newly created vPool using ViPR workflow.
  • Delete old ViPR vPool.
  • Rename the newly created ViPR vPool to the ‘Old pool name’

Renaming the new vPool with the old name results in a successful EHC StaaS provisioning task utilizing the original SRP. Continue reading

DellEMC EHC – ‘Onboarding A Local Cluster’ (Part 1)

The following two-part post details how to add an Enterprise Hybrid Cloud (EHC) vSphere Local Cluster, in EHC terms we refer to this cluster type as LC1S (Local Copy on One Site) other EHC cluster types include:

VS1S – vSAN Storage on One Site (not used by STaaS)
CA1S – CA VPLEX Metro Storage on One Site
CA2S – CA VPLEX Metro Storage across Two Sites
DR2S – DR RecoverPoint Storage across Two Sites

For details on how to add other cluster types please refer to the EHC Admin Guide:

Dell EMC – Enterprise Hybrid Cloud (EHC) 4.1.2

EHC LOGO

EHC (Enterprise Hybrid Cloud) which is the DellEMC turnkey VMware (vRealize Suite) based cloud offering has made great strides in recent releases transforming the cloud strategy for CPSD CI/HCI, namely EHC on VxBlock/VxRack Flex/VxRail (Engineered, manufactured, managed, supported and sustained as one product) and this release is no different with massive improvements around automation especially in relation to both the Install and Upgrade process associated with the EHC platform on VxRail leading to far quicker and more seamless deployments of the EHC stack. Enhanced multi-site capabilities, DRaaS offering on VxRail and factory delivered EHC on VxRack Flex w/NSX are some of the biggest milestones with this release. Continue reading

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 3.6 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 there are no EHC StaaS or VIPR native tasks being executed while performing the following procedure.

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
