Creating disks

Note: If the host is a virtual machine hosted on a hypervisor, review the notes in Creating disks for a virtual machine before creating virtual disks for virtual machines. The hypervisor must appear in the Hypervisors section of the ESI main window and a hypervisor host must be added after the hypervisor is connected and listed in the Hypervisors section or the disk creation will fail.

To create one or more disks or LUNs for a host:

  1. In the left pane of the ESI window, select the host.

  1. In the Actions pane, click Create Disk.

    The Create Disk wizard appears.

  1. Select the storage system, and then click Next.

  2. In the Storage Pool page, select a storage pool, and then click Next.

  3. In the New LUN page, set the following details for one or more new LUNs, and then click Next.



LUN Count

Number of disks to be created

Sequence Number

First number to append to the name for the first LUN

Note: For example,  to create three LUNs with the appended numbers 15, 16, and 17, type 3 in the LUN Count field and type 15 in the Sequence Number field.


Description for the disk or disks


Size and unit of measurement for each disk

Service Node

Storage processor that hosts the disk or disks

Provision Type
