volume create

Description

Creates a new volume and optionally maps the new volume to a server.

  • NOTE: To map an existing volume to a server, use volume map.

Format

volume create –name 
                                 string –size 
                                 integer [k|m|g|t] {options}
                              

Options

–boot
If present, designates the mapped volume to be a boot volume. The –boot and –lun options are mutually exclusive. Specifying the –boot option maps the new volume to lun0. If neither –boot nor –lun option is specified, the next available LUN is automatically assigned ( Storage Center 5.0 and later).
–controller 
                                 string
Specifies the name of the controller on which to activate the volume. See Mapping a Volume for information on the –controller option and mapping volumes.
–diskfolder 
                                 string
Specifies a disk folder for the volume.
–folder 
                                 string
Specifies the name of an existing volume folder in which to create the volume.
–folderindex 
                                 integer
Specifies the index of an existing volume folder in which to create the volume.
–h
Shows help for command options.
–localport 
                                 string
Specifies the WWN of the single local port to use for mapping when the –singlepath option is specified. Use this option with the –localport and –remoteport options to set the single port to use. (The –localport option is deprecated on Storage Center 5.0 and later.)
–lun 
                                 integer
Specifies the logical unit number (LUN) for the mapped volume. The –boot and –lun options are mutually exclusive. If neither –boot nor –lun option is specified, the next available LUN is automatically assigned ( Storage Center 5.0 and later). Dell EMC recommends that you allow LUNs to be automatically assigned to avoid issues with operating Storage Centers that require sequential LUN ordering.
–maxwrite 
                                 integer [k|m|g|t]
                              
Specifies the maximum size for volume writes. This value must be less than or equal to the volume size. By default, no limit is set for volume writes. Enter the number of 512-byte blocks or the total byte size. To specify a total byte size, use m for megabytes, g for gigabytes, or t for terabytes. For example, enter 32m to specify a block size of 32 MB.
–name 
                                 string
Specifies the volume name. This option is required.
–notes 
                                 string
Specifies notes for the volume. By default, no notes are included.
–pagesize 
                                 integer [k|m]
                              
Specifies the pagesize to use for the volume. If you specify a page size that does not exist on the Storage Center, the command terminates without creating the volume.
–readcache {true|false}
Enables or disables volume read cache. The default is false.
–redundancy 
                                 integer
Sets volume storage type. Available options are:
  • 0: Non-redundant
  • 1: Redundant
  • 2: Dual-redundant
The default is 1 (redundant). If you specify a storage type that has not been primed on the Storage Center, the command terminates without creating the volume. For information on storage types, see the

.
–remoteport 
                                 string
Specifies the world wide name (WWN) of the remote port for mapping the volume.
–replayprofile 
                                 string,…,
                                 string
Specifies one or more Replay profiles for the volume. Separate a series of Replay profile names with commas (,). If you specify an invalid Replay profile, the command returns an error and the volume is created without a Replay profile.
–server 
                                 string
Specifies the server for the volume. This is the server to which the volume or volume view will be mapped. See Mapping a Volume .
–serverindex 
                                 integer
Specifies the server index for the volume. This is the server to which the volume or volume view will be mapped. See Mapping a Volume.
–singlepath
Indicates that only a single port can be used for mapping. If omitted, all local ports are used for mapping. Use the –localport option to set the single port to use. See Mapping a Volume. ( The –localport option is deprecated on Storage Center 5.0 and later.)
–size 
                                 integer [k|m|g|t]
                              
Specifies the volume size. Enter the number of 512-byte blocks or the total byte size. To specify a total byte size, use k for kilobytes, m for megabytes, g for gigabytes, or t for terabytes. For example: enter 32m to specify a block size of 32 MB. This option is required.
–storageprofile 
                                 string
Specifies a Storage Profile for the volume. Use storageprofile show to show a list of available Storage Profiles.
–storageprofileindex 
                                 integer
Specifies a Storage Profile index for the volume. Use storageprofile show to show a list of available Storage Profiles.
–storagetype 
                                 string
Specifies a storage type for the volume. This option overrides values specified for the –redundancy, –pagesize, and –diskfolder options. If there is more than one storage type of the same name on the Storage Center, the first storage type found that matches the name is used.
–storagetypeindex 
                                 integer
Specifies a storage type index for the volume. When you specify this option, storage types are found by their indexes. Using this option guarantees that all storage types with the same name on a Storage Centerare found.
–writecache {true | false}
Enables or disables volume write cache. Specify true (or 1) to enable volume write cache or specify false (or 0) to disable volume write cache. The default is false.
