Create zSeries volume — Create volume nicknames

Introduction

Nicknames enable you to create values that have meaning to you and that are easy to remember. The nicknames that you specify here are unique and they identify specific volumes throughout the system.

Fields

Quantity of volumes

The number of volumes that is specified on the previous Define volume properties page.

Generate a sequence of nicknames based on the following

Check this box to specify, in the following fields, a sequence of volume names for the number of volumes that you created that is based on input in the prefix and suffix fields. Either a prefix or a suffix is required if this is selected. You can enter a value in one or both of the fields. The Prefix and Suffix fields can contain any characters except blank spaces and the Prefix and Suffix fields are stored (concatenated) in strings of up to 16 characters.

Note: Prefix and suffix combinations that result in volume nicknames that are greater than 16 characters returns the numbering sequence to 00000000. For example, if the nickname myVolume99999999 is created, the next volume regresses in numbering to myVolume00000000 (16 characters) instead of the next number in the sequence, myVolume100000001 (exceeding 16 characters).

The following fields are disabled if you do not make this selection.

Use hexadecimal sequence

Check this box to create a hexadecimal sequence of volume nicknames. The nickname suffix will be automatically incremented in a hexidecimal sequence of volume names for the quantity that you created. For example, if you create 400 volumes with the nickname prefix Vol and with the suffix beginning with 0000, the range of volume nicknames includes Vol0000 to Vol018F.

Note: You can only check this box if you checked Generate a sequence of nicknames based on the following.

Prefix

A prefix to the volume names. Either a prefix or a suffix is required if you checked Generate a sequence of nicknames based on the following. To disable this field, clear the box for Generate a sequence of nicknames based on the following. You can put a value in one or both of the Prefix and Suffix fields to establish a prefix or suffix to the volume nicknames. If you enter a numeric value for the prefix, the values increase sequentially to reflect the quantity of volumes that you want to create. If you enter an alphabetic value, it precedes and concatenates the suffix. For example, in the process of creating 400 volumes, if you put "myVol" in the Prefix field and "0000" in the Suffix field. These volumes are then nicknamed myVol0000 to myVol0399 for decimal sequences, or myVol0000 to myVol018F for hexadecimal sequences. If you enter only an alphabetic prefix and no suffix, a warning states that the volumes to be created will contain the same nickname.

Note: For OpenVMS and Tru64 Unix hosts, logical volume nicknames are reported to the operating system as the volume user-defined identifier (UDID). Be certain that this value conforms to the appropriate rules for UDIDs. See the topic OpenVMS UDID Support for more information.

Suffix

A suffix to the volume names. Either a prefix or a suffix is required if you checked the Generate a sequence of nicknames based on the following is checked. To disable this field, clear the box for Generate a sequence of nicknames based on the following. You can put a value in one or both the Prefix and Suffix fields to establish a prefix or suffix to the volume nicknames. If you enter a numeric value for the suffix, the values increase sequentially to reflect the quantity of volumes being created. If you enter an alphabetic value, the suffix follows and concatenates the prefix string. For example, in the process of creating 400 volumes, if you put the alphabetic characters "Disk" in the Prefix field and "0000" in the Suffix field, these volumes are then nicknamed Disk0000 to Disk0399 for decimal sequences, or Disk0000 to Disk018F for hexadecimal sequences. If you enter only an alphabetic suffix and no prefix, a warning states that the volumes to be created will contain the same nickname.

Note: For OpenVMS and Tru64 Unix hosts, logical volume nicknames are reported to the operating system as the volume user defined identifier (UDID). Be certain that this value conforms to the appropriate rules for UDIDs. See the topic OpenVMS UDID Support for more information.
