Create volume — Select extent pool

Introduction

Selecting an extent pool is required when you are creating a volume. If the list of extent pools do not meet your needs you can create an extent pool. After the extent pool has been created, the system refreshes and the new extent pool is displayed in the extent pool list.

Use the Refresh button to obtain current information.

The columns are defined as follows:

Provides the selection method (a radio button) to specify the extent pool that you want to assign to the volume. You can only select one extent pool at a time.

Nickname

Number

Specifies the extent pool number. The extent pool number is a four-digit decimal number with no leading zeros that is normally prefixed with a P (for example, P5 which is actually P0005). Even-numbered extent pools are associated with rank group 0. Odd-numbered extent pools are associated with rank group 1.

Primary Server

Specifies the primary server that is associated with the extent pool.

Available GB

Note: You cannot create volumes if the selected extent pool has a size smaller than the smallest size of a single volume. If this happens, a validation message is displayed that indicates that the volume cannot be created.

Create new extent pool button

Clicking this button displays the Create extent pool page that is the first page of the create extent pool wizard. The wizard directs you through the steps needed to create a new extent pool. After you create a new extent pool, the select extent pool table refreshes and you can select the extent pool that you created.
