Working With Stripe Groups

•Non-realtime MB/sec (optional): The lower threshold (in MB per second) that is reserved for non-realtime applications. If both Non-realtime MB/sec and Non-realtime IO/sec Fields are selected, then the system uses the lesser of the two values. This is an optional setting and can be left blank.

4Click OK.

5After the status screen indicates that the new stripe group has been added, click Close.

Caution: When you add a new disk or stripe group to your SAN, often an OS-dependent operation must be run to make the added device recognizable by a host. Some of these utilities can disrupt access to existing disks, causing access hangs or failures. To avoid this, stop all file system operations on the affected host before rescanning for the new device.

Use this procedure to modify a stripe group configuration.

1From the SNFS home page, choose Stripe Groups from the Config menu. The Configure Stripe Groups screen appears.

2Select from the File Systems drop-down menu the file system whose stripe group you want to modify.

3Select from the Stripe Groups list the stripe group you want to modify.
