Create Volume
Overview
This function creates new volumes.
The following types of volumes can be created.
Standard
The most commonly used volumes. Volumes are created in RAID groups or External RAID Groups.
Wide Striping Volume (WSV)
Volumes that are configured by multiple RAID group areas that are concatenated with striping to improve performance.
Thin Provisioning Volume (TPV)
Volumes that are created in TPPs. TPVs can also be used as the copy destination for SnapOPC or SnapOPC+.
Snap Data Volume (SDV)
Copy destination volumes for SnapOPC or SnapOPC+ that are created in the RAID group.
Snap Data Pool Volume (SDPV)
Volumes used as expansion areas for SDV that are created in the RAID group.
NAS Volume
Volumes used for NAS system operation (hereinafter referred to as "NAS user volume") in the Unified Storage environment that are created in TPPs.
Deduplication/Compression Volume
Volumes that have Deduplication, Compression, or both Deduplication and Compression enabled. The volumes are created in TPPs that have the Deduplication/Compression function enabled.
The ETERNUS DX60 S5 does not support the encryption function.
Volumes are formatted automatically when they are created in RAID groups or TPPs. If the error message "An internal resource is insufficient." appears after volumes are created, a format of volumes may have failed. Check the "Status" of the created volumes in the [Volume] screen. Refer to the [Volume (Basic Information)] function for details. Volumes in the "Readying" state have not been formatted. Wait until the currently running format processes are complete and reformat the relevant volumes. Refer to the [Format Volume] function for details.
- The maximum number of volumes that can be created is reduced in the following conditions:
When TPPs exist in the storage system
When concatenated volumes exist in the storage system
When REC Disk Buffers exist in the storage system
When Extreme Cache exists in the storage system
When Extreme Cache Pools exist in the storage system
When volumes undergoing RAID migration exist
When volumes undergoing Balancing TPV exist
When the Automated Storage Tiering feature is enabled
When Deduplication, Compression, or both Deduplication and Compression are enabled for the TPP
When the Veeam Storage Integration License is registered
Volumes are formatted automatically when they are created in RAID groups or TPPs. Standard, WSV, TPV, and SDV can be accessed from the host when host affinity is set after volume creation. NAS user volumes can be accessed from the host when NAS interface is set and shared folder is created after volume creation.
External Volumes are not formatted after a volume creation. They inherit the External LU Information of the External RAID Group (or the External Drive).
When a volume is created manually (*1), the volume number can be specified. Note that volumes have to be created one at a time. Multiple volumes cannot be created when specifying the volume number for a new volume.
*1 : Volumes can be created manually for WSVs or when drives are selected manually for Standard type volumes, SDVs, SDPVs, TPVs, NAS volumes, or Deduplication/Compression Volumes. When "Automatic" is selected to create a volume or when "Manual" is selected but a volume number is not specified, the volume number is allocated when a volume is created from the smallest unused decimal number in ascending order.
When "Manual" is selected, create the specified number of volumes by using the maximum free space that is available in the RAID group. Specifying a "Capacity" value is not required. "Standard", "WSV", and "SDPV" type volumes are created by using the maximum free space.
This function cannot be used to create an ODX Buffer volume. Refer to the [Create ODX Buffer Volume] function for details.
The Extreme Cache mode (enabled or disabled) of the storage system and the set states of the Extreme Cache mode for each volume are not linked. Regardless of the mode of the Extreme Cache for the storage system, the default state of Extreme Cache for each volume is "Enable". Note that External Volumes do not use Extreme Cache. Refer to the [Setup Extreme Cache] function in the [System] navigation for details about the Extreme Cache mode of the ETERNUS DX500 S5/DX600 S5/DX900 S5 and the ETERNUS DX8900 S4.
The Extreme Cache Pool mode (enabled or disabled) of the storage system and the set states of Extreme Cache Pool for each volume are not linked. Regardless of the mode of the Extreme Cache Pool for the storage system, the default state of Extreme Cache Pool for each volume is "Enable". Note that External Volumes do not use Extreme Cache Pool. Refer to the [Setup Extreme Cache Pool] function in the [System] navigation for details about the Extreme Cache Pool mode of the ETERNUS DX100 S5/DX200 S5.
Enabling or disabling Extreme Cache for each volume can be performed with Web GUI, CLI, or ETERNUS SF Storage Cruiser. Use the [Modify Cache Parameters] function to change the setting from Web GUI (for the ETERNUS DX500 S5/DX600 S5/DX900 S5 and the ETERNUS DX8900 S4).
Enabling or disabling Extreme Cache Pool for each volume can be performed with Web GUI or CLI. Use the [Modify Cache Parameters] function to change the setting from Web GUI (for the ETERNUS DX100 S5/DX200 S5).
In this manual, "volumes" include "External Volumes" if differentiation is not specifically required.

- Procedures for when the NAS user volume creation is not completed successfully
Confirm that the general status (detail) of the storage system and the status of the NAS Engine are both "Normal". If the status is not "Normal", the storage system requires maintenance.
The storage system general status (detail) can be checked in the [Storage] screen. Refer to the [Storage] function for details.
The NAS Engine status can be checked in the [Internal Parts] tab of the [Controller Module Detail] screen. Refer to the [Controller Module] function for details.
If the NAS user volume was created, delete the relevant volume. If the NAS user volume cannot be deleted, the storage system requires maintenance.
For the NAS user volume, "File" is displayed as the usage in the volume list screen ("NAS Data" is displayed as the usage details of the volume detailed information screen). Refer to the [Volume (Basic Information)] function for details.
Create the NAS user volume again. Confirm that the volume creation was successfully completed.

Naming Conventions for Creating Volumes
When creating multiple volumes at the same time, the volume name is automatically applied to the volumes according to the specified "Name", selected "Start of Suffix", and selected "Digits of Suffix".
(Example) When the specified volume name is "Volume" (six characters), "Start of Suffix" is "90", "Digits of Suffix" is "2", and the number of volumes is "11": the volume names "Volume90" to "Volume100" are applied to the volumes.
If the automatically applied volume name exceeds 32 characters due to the "Start of Suffix" and "Digits of Suffix" settings, the excess characters are deleted from the specified "Name", and replaced with a "~".
(Example) When the specified volume name is "ETERNUS_DXAF_Standard-XX_VolumeX" (32 characters), "Start of Suffix" is "90", "Digits of Suffix" is "2", and the number of volumes is "11": the volume names "ETERNUS_DXAF_Standard-XX_Volu~90" to "ETERNUS_DXAF_Standard-XX_Vol~100" are applied to the volumes.
When a volume name including the suffix number already exists, the suffix number is increased by one (+1). The suffix number is increased by one (+1) until no volume names overlap.
If "Start of Suffix" starts with "0" and it exceeds "Digits of Suffix", the zeros are deleted from "Start of Suffix" and then applied to the volume name.
(Example 1) When the specified volume name is "Volume", "Start of Suffix" is "000", and "Digits of Suffix" is "1": The volume name "Volume0" is applied to the volume.
(Example 2) When the specified volume name is "Volume", "Start of Suffix" is "00005", and "Digits of Suffix" is "2": The volume name "Volume05" is applied to the volume.
