To examine how a host is configured on a FlashArray, click on the host object in the vCenter inventory. To see a summary view, click on the Summary tab and identify the Everpure panel.

This shows all available FlashArrays and their connectivity status. For more information click on the Manage link or click directly on the FlashArray you would like more information on. Alternatively, click on the Configure tab, then Everpure > Host Connections.

This table shows the host object(s) that represent a given ESXi host on the FlashArray.

To view the host configuration on a specific FlashArray, select the FlashArray in the drop-down. If the desired FlashArray does not appear, ensure that it is added in the home screen of the Everpure plugin.

This table has the following columns:

  • Host: This is the network address of the ESXi host
  • Status: This indicates the configuration status of the host. The following are valid options:
    • Connected: This means that the ESXi host has a corresponding host object for that protocol on the array and the FlashArray sees it as online.
    • Not Connected: This means that the ESXi host has a corresponding host object for that protocol on the array but the FlashArray DOES NOT see it as online. This means the initiators are on the FlashArray, but connectivity is down. So for Fibre Channel this could be a zoning issue, and for iSCSI this could mean the hosts are not configured correctly or that there is a networking issue.
    • Not Configured: This means that the ESXi host does not have a corresponding host on the FlashArray at all.
  • Array Host Group: The name of the host group on the FlashArray that the corresponding host is in. For clustered hosts it is recommended to always put a host in a host group.
  • Array Host: The name of the host object on the FlashArray for the corresponding host.
  • Protocol: FC, iSCSI, or NVMe-oF

When a FlashArray is selected, the plugin will inquire the FlashArray for host configuration.

If there is no host for the ESXi host, it will show as Not Configured.

If there is a correctly configured host, it wil show as Connected. This will also show the host group it is in, and the protocol in use.

If a host is created but is not seen as online by the FlashArray (fabric FC or iSCSI login) that host will appear as Not Connected.

If the host is configured properly, but not in a host group, it will report a warning on the host.

If the host is configured for multiple protocols, more than one listing will appear.

Other hosts in this cluster are configured and in a host group but this specific host is not configured.

If the ESXi host personality has not been set for a host object, this screen will show that and offer a button to FIX this issue. More can be read about the ESXi host personality setting in Setting the FlashArray “ESXi” Host Personality.

For FlashArrays running 5.3.6 or earlier, DO NOT make this change online. If an ESXi host is running VMs on the array the host personality is being set on, data unavailability can occur. A fabric logout and login may occur and accidental PDL can occur. To avoid this possibility, only set this personality on hosts that are in maintenance mode or are not actively using that array. If the FlashArray is running 5.3.7 or later, the ESXi host personality can be set online.
