Configuration: Disk Groups and Virtual Disks

To change the segment size of a virtual disk:

1 In the AMW, select the Logical tab and select a virtual disk.
2 Select Virtual Disk Change Segment Size.
3 Select the required segment size.

A message prompts you to confirm the selected segment size. 

4 Click Yes.

The segment size modification operation begins. The virtual disk icon in the 

Logical pane shows an Operation in Progress status while the operation is 

taking place. 

To view the progress or change the priority of the modification operation, 

select a virtual disk in the disk group, and select Virtual Disk Change 

Modification Priority.

You can specify the virtual disk I/O characteristics for the virtual disks that 

you are defining as part of the storage array configuration. The expected I/O 

characteristics of the virtual disk is used by the system to indicate an 

applicable default virtual disk segment size and dynamic cache read prefetch 

setting. 

The dynamic cache read prefetch setting can be changed later by selecting 

Virtual Disk Change Cache Settings. You can change the segment size later by 

selecting Virtual Disk Change Segment Size.

The I/O characteristic types shown below are only presented during the create 

virtual disk process.
When you choose one of the virtual disk I/O characteristics, the 

corresponding dynamic cache prefetch setting and segment size that are 

typically well suited for expected I/O patterns are populated in the Dynamic 

cache read prefetch field and the Segment size field.
