Creating pass-through SCSI disks

If the selected hypervisor supports pass-through SCSI disks, then selecting Passthrough SCSI is an option when you are creating a disk for a virtual machine. See Creating raw device mapping disks if the hypervisor instead supports a raw device mapping disk.

To create one or more pass-through SCSI disks after adding a host:

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

  2. Select the host disk from the center pane.

  3. In the Actions pane, click Create Disk.

  4. The Create Disk wizard appears.

  5. Select Passthrough SCSI Disk as the disk type, and then click Next.

  6. In the Storage System page, select the storage system, and then click Next.

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

  1. In the New LUN page, set the following details for the disk or disks, and then click Next.

Field

Description

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.

Name

Name of the disk or disks

Description

Description for the disk or disks

Size

Size and unit of measurement for each disk

Service Node

Storage processor that hosts the disk or disks

Provision Type

Select either Thick or Thin

  1. In the Hypervisor Settings page, select the SCSI controller and SCSI controller location settings, and then click Next.

Note: For hypervisors, ESI does not support creating SCSI controllers. However, ESI uses existing SCSI controllers to create disks for virtual machines.

  1. In the Disk Preparations Settings page, set the following values for the disk or disks, and then click Next.

Field

Description

Partition Type

Type of partition to be created, either MBR (Master Boot Record) or GPT (GUID Partition Table)

File System

  • Partition Type of MBR: Either NTFS (New Technology File System) or FAT32 (File Allocation Table 32 bit

  • Partition Type of GPT: NTFS, the only available choice

Allocation Unit Size

Size of the allocation unit measured in bytes

Volume Label

Label for the volume

Drive letter or mount path

Drive letter or a mount path for the disk or disks

  1. In the Review Parameters Input page, review the settings, and then click Next to confirm them.

  1. In the Progress page, click Next.

    Note: Click More Information for more progress details. If a problem occurs while you are creating a disk, an error message appears along with options to resume or roll back the process. After the error is resolved, click Resume to resume the process. Click Rollback to revert to the previously executed step.

  2. In the Summary page, click Finish.

  3. The disk or disks appear in the list of Host Disks for the specific host and in the LUNs list under Storage Systems.
