6. A dialog box opens asking if you want to restripe existing media after bandwidth expansion.
Proceed as follows:
• Click Yes in most cases. This is the typical response. In any case this does no harm.
• Click No only if you are sure you do not need to restripe existing media, such as in the
following cases:
• You have very little existing media so the fact that it cannot use the new stripe group does
not impact future media operations or capacity.
• Your existing media is to be deleted soon so you don’ t care if it uses the new stripe group.
The first of a series of informational screens opens.
7. Work through the informational screens.
When prompted to retry, if you are not sure if the process started, you can retry to be sure. Doing
so does not cause problems.
The expansion process runs. A dialog box displays progress
8. Wait for the process to complete. On a large system this can take over 30 minutes.
9. A “…succeeded…” message is displayed when done. Click OK and Storage Utility closes.
10. The K2Config application displays a message informing you to restart servers. Click OK.
11. Make sure Storage Utility is closed before proceeding.
12. If directed, modify RTIOS.
Depending on your use of the expanded file system, you might need to change the RTIOS value.
This value can be calculated only by Grass Valley Support. Do this step only under the direction
of Grass Valley Support.
As directed, use a text editor to modify the SNFS configuration file on K2 Media Servers (both
primary and backup) with the role of media file system/database server.
NOTE: Don’t use the SNFS configuration tool to modify the system configuration. Doing so
causes unexpected changes in the configuration file, resulting in a failure of the expansion
process.
13. Restart all K2 Media Servers.
Make sure to first start servers with the role of media file system/metadata server.
When the server that takes the role of FTP server starts, one of the following happens:
• If you answered “Yes” to restripe existing media in the step above, the Restripe Utility
automatically launches and begins restriping media.
• If you answered “No” to restripe existing media in the step above, the Restripe Utility does
not launch.
