GRASS VALLEY K2 SAN, Installation And Service Manual

Page: 304 / 346

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.
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.
