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.

  • 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.

Caution

  • 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 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

  • WSVs are created by concatenating free areas that are the same size in multiple RAID groups.

    Refer to WSV specifications for details.

Note

  • 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.

  • 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.

    *1  :  Volumes can be created manually for WSVs or when drives are selected manually for Standard type volumes, SDVs, SDPVs, TPVs, 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 Pool mode (enabled or disabled) of the storage system and the setting state of the Extreme Cache Pool of 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 [Extreme Cache Pool] screen in the [System] navigation for details about the Extreme Cache Pool mode of the storage system.

  • 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.

  • In this manual, "volumes" include "External Volumes" if differentiation is not specifically required.

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_DX_Standard-XXXX_VolumeX" (32 characters), "Start of Suffix" is "90", "Digits of Suffix" is "2", and the number of volumes is "11": the volume names "ETERNUS_DX_Standard-XXXX_Volu~90" to "ETERNUS_DX_Standard-XXXX_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.

Note

  • 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.

Settings

In this screen, specify the details of the volumes that are to be created.

When creating Standard type volumes, SDVs, or SDPVs
  • Creating volumes in a RAID group

    • There are two methods to select a RAID group; "Automatic" and "Manual".

    • [The maximum number of volumes that can be created for each model] is applied to the total number of volumes in RAID groups, External RAID Groups, and Pools (TPPs and FTRPs).

    • For "RAID6-FR" type RAID groups, only "Standard" volumes can be created.

    • To create an SDV or SDPV, the Advanced Copy license is required.

    • The following list shows the conditions for creating SDPVs.

      • The volume capacity must be 2 TB or less

      • The volume capacity must be a multiple of SDPE capacity (1 GB/2 GB/4 GB) (*1)

        *1  :  To check the current SDPE capacity, refer to the [Snap Data Pool] screen in the [Advanced Copy] navigation.

    • Creating SDPVs in RAID groups with the same RAID level, drive type, number of drives is recommended.

  • Creating External Volumes in an External RAID Group

    • Select the "Enable" checkbox in the "Use External Drive" field.

    • The only available selection method for External RAID Groups is "Manual".

    • For External RAID Groups, only "Standard" volumes can be created. For the created External Volumes, "Usage" and "Usage Details" are "Migration".

    • The number of volumes cannot be specified when creating External Volumes in the External RAID Group. One External Volume is created in one External RAID Group.

  • For details on the setting items according to each volume type, refer to "Setting Items for Each Volume Type When Selecting "Automatic"" or "Setting Items for Each Volume Type When Selecting "Manual"".

When creating TPVs

  • Volumes are created in TPPs.

  • There are two methods to select a TPP; "Automatic" and "Manual".

  • When a TPP is created, a control volume is created for each RAID group that configures a TPP. Therefore, the maximum number of volumes that can be created in a TPP is calculated by using the following formula.

    Number of volumes that can be created in a TPP = Maximum number of volumes - Number of RAID groups that configure the relevant TPP
    Note that [The maximum number of volumes that can be created for each model] is applied to the total number of volumes in RAID groups, External RAID Groups, and Pools (TPPs and FTRPs).

  • When creating TPVs, "Enable" the Thin Provisioning function. Refer to the [Set Thin Provisioning] function for details.

  • The maximum total logical capacity of the TPVs that can be created in the storage system depends on the maximum pool capacity specified with the [Set Thin Provisioning] function. To check the maximum pool capacity, use the [Settings (Thin Provisioning)] function.

  • The total logical capacity of the TPVs that can be created at a time is 2 PB.

  • The total logical capacity of the TPVs that can be created in a single TPP is 48 PB.

  • For details on the setting items, refer to "Setting Items for Each Volume Type When Selecting "Automatic"" or "Setting Items for Each Volume Type When Selecting "Manual"".

When creating WSVs

  • The only available selection method for RAID groups is "Manual".

  • The conditions for RAID groups to configure WSVs are as follows:

    • The RAID level (RAID1+0/RAID5/RAID6/RAID5+0/RAID1/RAID0) must be the same

    • The number of member drives in the RAID group must be the same

    • The Stripe Depth value must be the same

    • The drive type (Online/Nearline/SSD/NVMe SSD/Online SED/Nearline SED/SSD SED/NVMe SSD SED) must be the same

      (Since the access performance of WSVs is reduced, selecting the same drive type for the "Drive Type" in the "Select RAID Group Information" field is recommended. Selecting "Online/Nearline" and "Online SED/Nearline SED" is not recommended.)

    • The drive speed must be the same

      (RAID groups configured with different speed drives can be selected. Note that this reduces the access performance for WSVs. It is recommended to select the same speed drives. The speed of the drives that configure a RAID group can be checked in the [RAID Group Detail] screen ([Drive] tab).)

    • The sector format (Advanced Format (AF) compliant/non-AF-compliant) must be the same

      (Selecting RAID groups that are configured with drives of the same sector format is recommended.)

    • The key group set state must be the same

      (If the drive type is "Online SED", "Nearline SED", "SSD SED", "NVMe SSD SED", or "Online SED/Nearline SED", RAID groups can be selected regardless of the key group setting (enabled or disabled). However, selecting the same key group set state is recommended. The key group set state can be checked with the "Encryption" field in the [Select RAID Groups] screen.)

    • The sequential unused area must be the same size or bigger than the capacity of the volumes that are to be concatenated

  • The number of concatenated RAID groups is from 2 to 64.

  • The WSV capacity is from 24 MB to 128 TB.

  • To expand the WSV capacity, use the RAID migration function instead of the LUN Concatenation function. Refer to the [Start RAID Migration] function for details.

  • RAID group capacity expansion for RAID groups which configure WSVs is not available (LDE cannot be performed). Refer to the [Expand RAID Group] function for details.

  • For details on the setting items, refer to "Setting Items for Each Volume Type When Selecting "Manual"".

When creating Deduplication/Compression Volumes
  • Deduplication/Compression Volumes can be created if all of the following conditions are satisfied.

    • The ETERNUS DX600 S6/DX900 S6 or the ETERNUS DX8900 S6 is used

    • The Thin Provisioning function is enabled

    • The Thin Provisioning Pool capacity is not in a depleted state

    • Deduplication/Compression for the storage system is enabled

    • The Deduplication, Compression, or both Deduplication and Compression setting (hereinafter referred to as "Deduplication/Compression setting of the TPP" in this manual) is enabled for the TPP where the Deduplication/Compression Volumes are to be created

    • The status of the Data Container Volume in the TPP where the Deduplication/Compression Volumes are to be created is not "Readying", "Not Ready", "Broken", or "Data Lost"

  • Deduplication/Compression Volumes are TPVs that have Deduplication, Compression, or both Deduplication and Compression enabled. The volumes are created in TPPs that have the same Deduplication/Compression setting.

  • There are two methods to select a TPP; "Automatic" and "Manual".

  • Deduplication, Compression, or both Deduplication and Compression for data are performed synchronously with the host I/O.

  • For the Deduplication/Compression Volume, a physical capacity as large as the chunk size is used for each volume regardless of the host I/O when the volume is created. Make sure to check the free space in the TPP before creating the volume.

  • The total logical capacity of the Deduplication/Compression Volumes that can be created at a time is 2 PB.

  • The total logical capacity of the Deduplication/Compression Volumes that can actually be created in a single TPP by the customer is limited to the logical capacity of the Data Container Volume in the relevant TPP.

    • If the efficiency of the Deduplication/Compression function cannot be estimated, setting the total logical capacity of the Deduplication/Compression Volumes smaller than the logical capacity of the Data Container Volume is recommended.

    • If the efficiency of the Deduplication/Compression function can be estimated, the total logical capacity of the Deduplication/Compression Volumes must be less than or equal to ten times the logical capacity of the Data Container Volume.

  • If the Deduplication/Compression setting for the TPP is enabled, Deduplication/Compression target volumes (volumes that have Deduplication/Compression enabled) and non-Deduplication/Compression target volumes (TPVs that have Deduplication/Compression disabled) can be created in the same TPP. If both volumes exist, the performance of the non-Deduplication/Compression target volumes (TPVs) may be degraded. To reduce performance degradation of non-Deduplication/Compression target volumes (TPVs), do not create these volumes in the same TPP.

  • If Deduplication/Compression Volumes larger than the logical capacity of the Data Container Volume are deleted or formatted repeatedly, creation of the Deduplication/Compression Volume may fail due to a temporary capacity shortage. If this error occurs, wait a few minutes before starting this function.

  • Non-Deduplication/Compression target volumes (TPVs) can be changed to Deduplication/Compression target volumes. Also, Compression target volumes (Compression Volumes) can be changed to non-Compression target volumes. Refer to the [Start RAID Migration] function for details.

  • "Provisioned Capacity" for TPVs that are created in the storage system does not include the Deduplication/Compression Volume capacity. Refer to the [Thin Provisioning Pool (Basic Information)] function for details.

  • The following information for Deduplication/Compression Volumes can be checked. Refer to the [Volume (Basic Information)] function for details.

    • Pre-compression data capacity (Original Data Size) that is written to the relevant TPV.

    • Usage rate that uses the pre-compression data capacity as the used capacity.

  • The following performance information for Deduplication/Compression Volumes can be checked. Refer to the [Performance (Host I/O)] function for details.

    • The compression rate of the data that is written to the Deduplication/Compression Volume from the host.

    • The percentage of data that is not suited for the basic data size of the compression process (Unaligned I/O Rate).

  • For details on the setting items according to each volume type, refer to "Setting Items for Each Volume Type When Selecting "Automatic"" or "Setting Items for Each Volume Type When Selecting "Manual"".

Item Description Setting values

Name

Specify the volume name.

An existing volume name cannot be specified. Volume names starting with "$SYSVOL", "$VVOL_META", or "$DATA_CNTNR" cannot be used.

When creating multiple volumes at the same time, the new volumes are named automatically. Refer to Naming Conventions for Creating Volumes for details.

Up to 32 alphanumeric characters,

symbols (except "," (comma) and "?"),

and spaces

Capacity

Specify the volume capacity and select the unit of capacity.

Up to a 15-digit number including the "." (decimal point) can be input. Note that when "MB" is selected, the specified value is rounded down to the nearest whole number. When "GB" or "TB" is selected, the specified value is converted to "MB" and rounded down to the nearest whole number.

Caution
  • An error screen appears in the following conditions:

    • Free space in the RAID group is insufficient

    • The total capacity of TPVs or Deduplication/Compression Volumes that can be created in a single operation exceeds 2 PB.

      • For Automatic Setting

        Total capacity = Capacity × Number of volumes

      • For Manual Setting

        Total capacity = Capacity × Total number of volumes for each TPP

  • If "Use all Largest Free Space" is selected when creating volumes manually, inputting the capacity is not required. The specified value and unit are not used.

  • If the same capacity is entered in the same format (digits and units (GB/TB)) as the "Largest Free Space", all of the largest free space is used. To add the capacity without adjustments, input the capacity in units of MB.

  • Create any of the following types of volumes in advance when using SnapOPC or SnapOPC+.

    • SDV and SDPV (the SDV is created with the minimum necessary capacity)

    • TPV

  • The maximum logical capacity of Deduplication/Compression Volumes (or the total logical capacity of Deduplication/Compression Volumes in a TPP) varies depending on the logical capacity of the Data Container Volume in the relevant TPP. If the efficiency of the Deduplication/Compression function cannot be estimated, setting the maximum logical capacity of the Deduplication/Compression Volumes smaller than the logical capacity of the Data Container Volume is recommended.

  • When creating multiple volumes in a RAID group, the maximum number of volumes that can be created for the user capacity may be reduced. To use the entire user capacity, the volume size must be an exact multiple of the basic size (stripe size). Refer to "Basic Size for each RAID Level" for details.

  • If all of the following conditions are satisfied, the capacity cannot be entered.

    • "Standard" is selected for "Type"

    • The "Enable" checkbox in the "Use External Drive" field is selected

Note

  • To create a volume that is larger than the largest free space, concatenate the free spaces in the RAID group to the existing volume. These volumes cannot be created by only using this function. Refer to the [Expand Volume] function for details.

  • When creating an SDV, 24 (MB) + "Capacity of source volume only SDV" × 0.1 [%] is automatically secured in the storage system. This setting is not required. "24 (MB)" is the smallest volume capacity. "Capacity of source volume only SDV" × 0.1 [%] is the capacity that is used for the controlling information area in the SDV.

  • The same input condition as the TPVs is applied for the Deduplication/Compression Volume capacity.

  • The number of entered characters includes the "." (decimal point) and the "0" before the decimal point.

    (Example) 0.1234567890123 (15 characters)
