Creating open systems volumes

Complete this task to create open systems volumes and to specify their attributes and properties.

1. In the navigation, select Real-time manager or Simulated manager > Configure storage > Open systems > Volumes – Open systems. On the Volumes – Open systems main page, in the Select storage unit list, select a storage unit.
2. Select a volume. From the Select Action list, select Create..., and then click Go. The Create Volume – Select extent pool page is displayed.
3. You must select an extent pool for the target volumes. After you select the extent pool, click Next. The Create Volume – Define volume characteristics page is displayed.
   Note: If there are no available extent pools available for selection, you can create one by clicking the Create new extent pool button. When you have finished creating an extent pool, you are returned to this page, and the extent pool that you created is available for selection.
4. In Create Volume – Define volume characteristics, define the volume type for the new volumes. You can select any number of volume groups from the Select volume groups list to associate with the new volumes. After you define the volume characteristics, click Next. The Create Volume – Define volume properties page is displayed.
5. Define the volume properties. To calculate the maximum size, enter a value in the Quantity field and click the Calculate max size button. To calculate the maximum quantity, enter a value in the Size field and click the Calculate max quantity button. The Extent size and Available Storage Capacity in Extent Pool fields are displayed in the units that correspond to the selected volume type.

   If you click the Calculate max size button, the Size field is populated with the calculated value. You can overwrite the value and enter an integer value for a lesser size. If you selected one of the iSeries volume types on the previous Define volume characteristics page and Decimal GB (10⁹ bytes) for the capacity units, the values here include 8.56, 17.54, 35.16, 36.00, 70.56, 141.12, and 282.25. If you selected one of the iSeries volume types on the previous Define volume characteristics page and Binary GB (2³⁰ bytes) for the capacity units, the values here include 8.00, 16.34, 32.75, 33.53, 65.72, 131.44, and 243.80.

   If you select the Select LSSs for volumes checkbox, you are required to select from the list of available LSSs for these open systems volumes.

   After you define the volume properties, click Next. The Create Volume – Create volume nicknames page is displayed.

6. In Create Volume – Create volume nicknames, you can optionally create one or more nicknames that are based on entries in the Prefix or Suffix fields. If you do not specify nicknames, only a volume number is created. Click Next. The Create Volume – Verification page is displayed.
   Tip: If you plan to create volume groups, you can use a unique and meaningful nickname that can help you easily find the volumes that you want to include in a volume group. For example, if you are creating multiple volumes of data for a specific department, you can make the nickname prefix an abbreviation of that department's name. Then you can use a predetermined range of numbers in the nickname suffix to identify each individual volume.
7. In Create Volume – Verification, review the attributes and values to verify that they are correct. If the attributes and values are not correct, click Back as appropriate to return and to specify the correct values. Otherwise, click Finish to complete the volume creation process.
