Procedures for expanding the media file system by bandwidth
Grass Valley personnel who have received K2 SAN training can use the following procedures.
Prepare system for bandwidth expansion
1. If a redundant K2 Storage System, do the following:
a) Verify that MPIO is updated to the latest version on all shared storage K2 clients.
b) Put the system into an “original primary” state.
This means that for all redundant devices (switches, servers, RAID controllers, etc.) the current
device acting as primary is the one that was initially configured as primary when the system
was originally installed.
2. Back up configuration files from the primary K2 Media Server. To do this, save a copy of the
following files to a different location:
D:\snfs\config\cvlabels
D:\snfs\config\default.cfg
On some systems this file is named gvfs_hostname.cfg, where hostname is the name of the
SNFS file system server.
If there is a problem with the expansion process, contact Grass Valley Support for instructions
on using these files to recover.
3. If K2 storage contains Aurora media, do additional steps.
4. Verify recovery disk images. Update if necessary

Set up and configure RAID for bandwidth expansion
1. Rack any new RAID equipment
2. Stop all media access and power down K2 clients and other clients.
3. Clean unreferenced files and movies.
K2 Media Servers with role of file system/metadata server, both primary and redundant, must
be powered up but offline.
4. Power down the remaining devices of the K2 SAN.
5. Add disks or RAID equipment to support the additional RANKs
As applicable, remember to set Fibre Channel addresses on RAID controllers and chassis addresses
on Expansion Adapters.
6. Start up the RAID equipment.
7. Start up the primary K2 Media Server.
If there are multiple K2 Media Servers, this is the server that takes the role of media file system
server. On a redundant K2 SAN, this is the server functioning as primary when the system was
last powered down.
