13. In Storage Utility, select
Tools | Expand File System By Capacity
.
The first of a series of informational screens opens.
14. Work through the informational screens to verify information. When the option to retry becomes
available, if the new disks are not labeled correctly, retry to start the process. If you are not sure,
you can retry to be sure. Doing so does not cause problems.
15. A message box reports progress. When a message reports success, the process is complete.
16. Restart the K2 SAN.
17. If a redundant K2 SAN, test failover capabilities.
Expanding the media file system by bandwidth
If you want to retain your media file system and yet expand the bandwidth of your K2 SAN, you
must use the following procedures for dynamic bandwidth expansion. This process allows you to
add RANKs to the stripe group, thereby expanding its width, without reinitializing the file system.
This keeps the existing media intact. The additional RANKs can be made up of new disks in existing
RAID chassis, disks in new Expansion Chassis, or disks in new primary RAID chassis.
After the file system is expanded, existing media is still striped across the original narrower stripe
group, so it can not take advantage of the increased bandwidth. Also, if there is a significant portion
of the storage pool occupied by this existing media, its presence reduces the extent to which new
media can use the increased bandwidth. For this reason the dynamic bandwidth expansion process
provides the Restripe Utility, which restripes the existing media across the new wider stripe group.
This enables both the existing media and new media to get full benefit of the increased bandwidth.
If the media on your file system has a high turnover rate and you know existing media is to be
deleted soon, you have the option of disabling the Restripe Utility. This saves the system resources
and time required to restripe media.
The expansion chassis that you add to your K2 SAN must have unbound, unlabeled disks. If it
currently has disks bound or labeled, connecting it to your system can cause errors.
Dynamic bandwidth expansion is supported only with K2 system software version 3.2 and higher.
Dynamic bandwidth expansion is supported on systems with one LUN per RANK and on systems
with multiple LUNs per RANK.
NOTE: Adding RAID storage devices changes your system design and must be specified for your
K2 SAN by Grass Valley. Do not attempt to add RAID storage devices without support from Grass
Valley.
