If the FlashArray is running 5.3.7 or later the ESXi host personality can be set online.

To avoid this possibility, only set this personality on hosts that are in maintenance mode or are not actively using that array. A fabric logout and login may occur and accidental PDL can occur. If an ESXi host is running VMs on the array you are setting the host personality on, data unavailability can occur. So it is highly recommended to do so.įor FlashArrays running 5.3.6 or earlier, DO NOT make this change online. While it is supported to have an unmatching count, it makes cluster-based provisioning simpler, and a variety of orchestration integrations require these to match. It is recommended to not have more or less hosts in the host group as is in the cluster. The host group and its respective cluster should have the same number of hosts. Every ESXi host that is in the cluster should have a corresponding host (as described above) that is added to a host group. Therefore, with every VMware cluster that will use FlashArray storage, a respective host group should be created. In order to provide simple provisioning, Pure Storage also recommends creating host groups that correspond to VMware clusters. Pure Storage recommends grouping your ESXi hosts into clusters within vCenter-as this provides a variety of benefits like High Availability and Dynamic Resource Scheduling.

Host Group-a host group is a collection of host objects.

In the example below, the ESXi host has two online Fibre Channel HBAs with WWPNs of 21:00:00:0e:1e:1e:7b:e0 and 21:00:00:0e:1e:1e:7b:e1 So creating a multi-protocol host object should be avoided on the FlashArray when in use with VMware ESXi. Furthermore, while the FlashArray supports multiple protocols for a single host (a mixture of FC, iSCSI & NVMe), ESXi does not support presenting VMFS storage via more than one protocol. If an initiator is not yet zoned (for instance), and not intended to be, it can be omitted from the FlashArray host object. Every active initiator for a given ESXi host should be added to the respective FlashArray host object.

A FlashArray host object must have a one to one relationship with an ESXi host. Host-a host is a collection of initiators (Fibre Channel WWPNs, iSCSI IQNs or NVMe NQNs) that refers to a physical host.The FlashArray has two object types for volume provisioning, hosts and host groups: The purpose is to outline the proper configuration for general understanding. This section describes the recommendations for creating provisioning objects (called hosts and host groups) on the FlashArray.
