Follow

The following instruction require Host PowerTools for VMware release 6.1 or above. Do NOT follow these instructions with older releases.

It is strongly recommended to use the latest Host PowerTools for VMware release available.

When using Host PowerTools for VMware to help with the following operations, make sure to provide credentials for the relevant InfiniBox system. 

Without the credentials, Host PowerTools for VMware can neither validate the hosts and clusters are registered correction nor fix the registration.

Adding new hosts to a registered cluster

When adding a new host to an already registered cluster, the cluster should be re-registered 

Instructions

  1. Connect the new host to the InfiniBox system(s) that the other hosts in the cluster are also connected to
  2. Select the host object, and locate the Host PowerTools for VMware Infinidat View
    Follow the instructions here: Locating the Infinidat View
  3. Register the host with the relevant InfiniBox system(s)
  4. Add the host to the desired cluster
  5. Select the cluster object, and locate the Host PowerTools for VMware Infinidat View
    Follow the instructions here: Locating the Infinidat View
  6. Refresh the page using the Host PowerTools menu, so that Host PowerTools for VMware identifies that the cluster registration is incomplete
  7. Click the Fix Cluster Registration button which Host PowerTools for VMware presents
    InfiniBox best practices settings will be applied to the new host
  8. Refresh the System List by pressing the Refresh Page option on the top right "more options" menu

Removing a host from a registered cluster

When removing a registered host from a cluster, both host and cluster should be re-registered 

The order of the following steps is important - incorrect steps may cause Host PowerTools for VMware to fail during cluster re-registration.

In such a case, the cluster registration should be complete using InfiniBox CLI or GUI.

Instructions

  1. Place the host in maintenance mode 
  2. Remove the host from the cluster 
    1. Note: do not rename the host 
  3. Make sure no VMs (that use an InfiniBox datastore) exist on the host 
    1. Such VMs are already powered-off, since the host is in maintenance mode
    2. Either remove the VMs from the vSphere inventory or migrate them to another host in the cluster
  4. Unmount any InfiniBox datastores from the host
  5. Reboot the host 
  6. Select the cluster object, and locate the Host PowerTools for VMware Infinidat View
    1. Follow the instructions here: Locating the Infinidat View
  7. Refresh the page using the Host PowerTools menu, so that Host PowerTools for VMware identifies that the cluster registration is incomplete
  8. Click the Fix Cluster Registration button which Host PowerTools for VMware presents
    1. HPT-VM will remove the host entity from the cluster entity in InfiniBox
    2. Note: this unmaps all volumes from the removed host
  9. Exit the host from maintenance mode

When moving a registered host between clusters, both host and cluster should be re-registered 

The order of the following steps is important - incorrect steps may cause Host PowerTools for VMware to fail during cluster re-registration.

Instructions

  1. Place the host in maintenance mode 
  2. Move the host from the original cluster to the new cluster
    1. Note: do not rename the host 
  3. Make sure no VMs (that use an InfiniBox datastore) exist on the host 
    1. Such VMs are already powered-off, since the host is in maintenance mode
    2. Either remove the VMs from the vSphere inventory or migrate them to another host in the cluster
  4. Unmount any InfiniBox datastores from the host
  5. Reboot the host 
  6. Select the original cluster object, and locate the Host PowerTools for VMware Infinidat View
    1. Follow the instructions here: Locating the Infinidat View
  7. Refresh the page using the Host PowerTools menu, so that Host PowerTools for VMware identifies that the cluster registration is incomplete
  8. Click the Fix Cluster Registration button which Host PowerTools for VMware presents
    1. HPT-VM will remove the host entity from the cluster entity in InfiniBox
    2. Note: this unmaps all volumes from the removed host
  9. Exit the host from maintenance mode
  10. Select the new cluster object, and locate the Host PowerTools for VMware Infinidat View
    1. Follow the instructions here: Locating the Infinidat View
  11. Refresh the page using the Host PowerTools menu, so that Host PowerTools for VMware identifies that the cluster registration is incomplete
  12. Click the Fix Cluster Registration button which Host PowerTools for VMware presents
