120 Configuration: Disk Groups and Virtual Disks

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.

NOTE: 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.

Changing the I/O Type

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. For more information about the Automatic Configuration Wizard,

see the PowerVault Modular Disk Storage Manager online help topics.

NOTE: 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.

To change the I/O type:

Select from these virtual disk I/O characteristic types, based on your

application needs:

•
