Create a host group

Contributors Download PDF of this page

There are two ways to create a host group:

  • From the Host Groups page, described below.

  • As part of creating a new disk. Use this method when you need to create a host group on a block store that has not yet been initialized. For more information see Create a new disk.

    It is possible to create an empty host group and map it to a disk as a placeholder. You must update the empty host group to add initiators before you will be able to access the storage.

Before you begin

You need the following to create the host group:

  • The subtenant, region and zone in which to create the host group.

If the block store for a subtenant/zone combination has not been previously initialized, you will not be able to create a host group using this method. An alternative is to follow the Create a new disk process, which allows you to initialize the block store and create a host group as part of the process.
  • A name for the host group

  • The host group protocol: iSCSI or FCP

  • The list of initiators to add to the group: WWPNs for FC hosts nodes or IQNs for iSCSI host node names.

  • An alias for each initiator; an alias is a simple name to identify the initiator server, or an individual port/interface on the server. For example, Server 4.

Steps

  1. Display the Host Groups list.

  2. Click Create Host Group.

  3. On the Create Host Group page:

    1. Select the protocol: iSCSI or FCP.

    2. Select the subtenant, region, and zone and for the host group.

  4. Specify a name for the host group.

  5. Select the OS Type: the disk operating system.

  6. Add the Initiators for the group. For each initiator, specify the alias and the initiator.

  7. If required, add tags (key-value pairs) to the host group in the Tags section.

  8. Click Create. This creates the host group.

After you finish

After the host group is created, it is available for mapping to disks.
