Create volume — Create volume nicknames

Introduction

The Create volume nicknames page is generally displayed with two check marks in the checkboxes. This allows you to specify a nickname for the volumes you are creating by providing a prefix and suffix, which makes your names unique. You can choose not to generate nicknames (not recommended) for your volumes by removing the check mark from the first check box and clicking NEXT.

Fields

Quantity of volumes

The amount of volumes that is specified on the previous Define volume properties page. This is an informational field and acts as a reminder of the number of nicknames that must be created.

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 amount 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 check box 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 in strings of up to 16 characters. The values can either be hexadecimal (you must check the Use hexadecimal sequence check box) or decimal (if the Use hexadecimal sequence is not checked).

Note: Prefix and suffix combinations that result in volume nicknames that are greater than 16 characters will return the numbering sequence to 00000000. For example, if the nickname myVolume99999999 is created, the next volume returns the 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 click the Generate a sequence of nicknames selection.

Use hexadecimal sequence

This check box is automatically marked when you mark the Generate a sequence of nicknames based on the following check box. The hexadecimal sequence designation creates a hexadecimal sequence of volume nicknames. The nickname suffix automatically increments in a hexadecimal sequence of volume names for the quantity that you create. For example, if you create 400 volumes with the nickname prefix Vol and with the suffix beginning with 0000, the range of volume nicknames that includes Vol0000 - Vol018F.

Prefix

Specifies the prefix that you want to add to the volume nicknames. (The prefix is counted as part of the 16 character limitation that is allowed for a nickname). A value in both the Prefix and Suffix fields avoids the problem of volumes being named with the same nickname.

This field is limited to alphabetic characters (A - Z, a - z). If you enter a numeric value for the prefix, the values increase sequentially to reflect the amount of volumes that you want to create. If you enter an alphabetic value, it precedes and joins 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 named myVol0000 - myVol018F for hexadecimal sequences. If you did not check the hexadecimal sequence box, your volumes are named myVol0000 - myVol0399.

Notes:

1. If you enter only an alphabetic prefix and no suffix, a warning is displayed that states that the volumes to be created will contain the same nickname.
2. 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. Review the HP OpenVMS documentation for the UDID rules.

Suffix

Specifies the suffix that you want to add to the volume nickname. (The prefix is counted as part of the 16 character limitation that is allowed for a nickname). A value in both the Prefix and Suffix fields avoids the problem of volumes being named with 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. Review the HP OpenVMS documentation for the UDID rules.
