GRASS VALLEY K2 SAN, Installation And Service Manual

10. You now have a blank (empty) file system. Proceed as follows:
• On a 7.x SAN, you also have a blank database. Do not perform additional operations on the
database. Skip to the next step in this procedure.
• On a 3.x SAN, the media database still contains references to media files which are no longer
present in the file system. To clear the media database do the following:
a) In the K2Config application tree view, open the node for the K2 Media Server and select the
Database Server
node to open its property page.
b) On the Database Server property page click
Erase media database
.
A message box displays progress.
c) Wait until a message confirms that the process is complete. This can take several minutes.
d) If you have redundant K2 Media Servers, repeat these steps to clear the media database on
the other (redundant) server.
11. Close Storage Utility.
12. If you have Macintosh systems accessing the K2 SAN, you should check that the SNFS file
system volume is configured correctly on the Macintosh systems.
13. Place the K2 SAN back online.
Expanding the media file system by capacity
Prerequisites are as follows:
• The system must have one LUN per RANK. Expansion by capacity is not supported on systems
with multiple LUNs per RANK.
• The expansion chassis that you add to your K2 SAN must have unbound, unlabeled disks.
NOTE: This procedure should only be attempted under the supervision of qualified Grass
Valley support personnel. Contact your Grass Valley representative for assistance.
If you need to increase the storage capacity of your K2 SAN, you can do so by adding one or more
Expansion Chassis, up to the maximum number of chassis allowed for your level of storage.
1. Rack the Expansion Chassis.
2. If a redundant K2 SAN, 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.
3. On the K2 Media Server with the role of primary media file system/metadata server, save a copy
of the following files to a different location:
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.)
D:\snfs\config\cvlabels
4. Power down the K2 SAN, including RAID storage devices.
5. Power up the RAID storage devices. Verify that they stabilize in an operational state with no
errors indicated.
6. Power down RAID storage devices.
