If you select an unacceptable configuration, the Finish button remains gray and unavailable until you correct the configuration. Examples are an odd number of drives for a mirrored stripe configuration, 1 or 2 drives for a parity volume, and 1 drive for a Mirror configuration. If you specify a volume larger than the selected drives can support, an error message appears after you click the Finish button. Click OK to remove the message, then repeat this procedure and specify a smaller volume. Table 5-6 Manual Create Volume Wizard - Select Volume Type to Create Screen Settings Name Size Setting Configuration Chunk Size Description Enter the name of the volume you are creating. Enter the size of the volume you are creating ((MB, GB, TB, etc.). Do not type a decimal point. Use the drop-down box to select the volume capacity: Select the desired organization (JBOD, Stripe, etc.). Table 5-2 lists the volume organizations. Select the size (32K, 64K, etc.) of each chunk from one of the commonly used chunk sizes. If you selected JBOD or Mirror as your configuration setting, the Chunk Size setting is gray and unavailable. After a volume is created, you can use the Advanced tab to write-protect the volume and suppress Synch Cache commands from the host (see 5.4.1.4). 5.4.1.2 Expanding a Volume If you want to add capacity to a volume, expand the volume to increase its physical capacity. 1. In the Logical Resources tab, click the volume whose capacity you want to expand. 2. On the Storage menu, click Expand Volume. The Expand Volume dialog box appears (see Figure 5-15). xStack Storage User's Guide 63
