Hypervisor cluster volumes

The hypervisor cluster volumes are the shared SAN volumes attached to a hypervisor cluster to provide storage resources for virtual machines deployed on this cluster. The volumes configured on the hypervisor cluster profile are configured on all the hypervisors in the cluster. These SAN volumes can be of FC, iSCSI, or FCoE.

The SAN storage volumes that have been configured in the associated server profile template are automatically populated within the Storage section during create, edit, or import cluster profile operations and these cannot be removed. The volumes in the server profile template can be made available across multiple hypervisor cluster profiles using the same server profile template. In addition to SAN volumes configured in the server profile template, you can also add or remove these additional storage volumes from the hypervisor cluster profile. These additional storage volumes are specific to each hypervisor cluster profile and are not shared across multiple hypervisor cluster profiles.

The hypervisor cluster volumes can be formatted with VMFS (Virtual Machine File System). If you do not want to format the volumes, you can select Unmanaged as the file system option.

While using iSCSI volumes, do not change CHAP level settings. These setting changes require a manual update on the hypervisor manager. Also, do not regenerate CHAP secrets (passwords) in server profiles that correspond to hypervisor profiles.

Hypervisor cluster profile does not automatically reconfigure the datastore to storage volume size changes. To increase the datastore capacity, increase the size of the storage volume on which the datastore is created, and then using the hypervisor manager user interface, increase the datastore capacity

Auto and Manual are the two LUN types available in HPE OneView. If you select the Auto option, the LUN IDs are assigned for the cluster-defined volumes. If you select the Manual option, you have to provide the LUN IDs for the cluster-defined volumes. By default, Auto option is selected for all the cluster-defined volumes attached to a cluster. Ensure that you do not have any powered on VMs running on the cluster while performing the LUN ID changes.

NOTE:
  • Once added, a hypervisor cluster volume cannot be modified.

  • Cluster volume names must not conflict with local datastore names on the hypervisor hosts in a cluster.

  • Do not use LUN ID 256 in a hypervisor cluster profile while you attach and edit storage volumes due to VMware limitations.
