mkvolgrp

Parameters

If you are using an HP-UX operating system, the number of volumes in the volume group must not exceed 7 volumes. This restriction only applies when the hostconnect attribute for the -addrdiscovery parameter is set to reportlun and the associated volume group is of type scsimap256.

-dev storage_image_ID

(Optional). Specifies the storage image ID, which includes manufacturer, machine type, and serial number. This parameter is required if you do not specify a fully qualified volume group name.

Example: IBM.1750-68FA120

-hosttype host_type

(Optional) Use this parameter as an alternative method for specifying the type of Volume Group.

Note: You cannot use this parameter with the -type parameter.

-type | scsimask | scsimap256 | os400mask |

(Optional). Specifies the type of the volume group.

scsimask (default)

Creates a SCSI mask volume group. This option is available if the host adapter supports four-byte LUN addresses.

scsimap256

Creates a SCSI-MAP 256 volume group.

os400mask

Creates an OS400 mask volume group. The IBM iSeries host system typically uses fixed block volumes of 520-byte logical block size. This option is available only if the host adapter supports four-byte LUN addresses.

Note: This volume group is also referred to as SCSI520-MASK. When an error message is displayed for the OS400 MASK, SCSI520-MASK is referenced instead.

Note: You cannot use this parameter with the -type parameter.

-volume volume_ID | . . .

(Optional). Specifies the array of volume IDs to include in the volume group. For the -type scsimap256 parameter, the array cannot exceed 256 volume ID entries. Otherwise, up to 64 384 entries are allowed.

The volume ID is a 32-bit number that can be represented as 4 hexadecimal digits in the form of XYZZ where X is the address group (0 - 1), XY together is the logical subsystem number 00 - 1E (for 1750) , and ZZ is the volume number (00 - FF).

To specify a range of volume IDs, separate the volume IDs with a dash (–).

You must separate multiple volume IDs or ranges of volume IDs with a comma between each ID or range of IDs.

Example: 0100-010F,0180-018F,0120

-lun lun_ID

(Optional)Specifies the LUN ID in hexadecimal value (00 - FF) which is mapped to the specified volume ID for a SCSI-MAP256 type volume group. If multiple volume IDs are specified by the -volume parameter, LUN IDs are assigned consecutively in incremental order.

Note: This parameter is only valid for a SCSI-MAP 256 type volume group. If this parameter is specified for any other type of volume group, the command fails.

Volume_Group_Name | -

(Required). Specifies the volume group name, not to exceed 16 characters. Ensure that the name is unique within the scope of the storage image. Accepts a fully qualified volume group name or a shortened version, if the -dev parameter is specified.

If you specify the dash (-), this parameter information is automatically supplied.
