Expanding the media file system by capacity
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.
7. Close Storage Utility.
8. 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. Refer
to procedures in
Chapter 13, K2 FCP Connect access for Final Cut Pro systems on
page 470 .
9. Place the K2 SAN back online.
Expanding the media file system by capacity
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.
When expanding by capacity, the number of LUNs or RANKs added must be a
multiple of the number of LUNs or RANKs currently in the system. For example, if
the current system has four (4) RANKs, then you can add an additional four (4 X 1)
RANKs, eight (4 X 2) RANKs, twelve (4 X 3) RANKs, etc.
The expansion chassis that you add to your K2 SAN must have unbound, unlabeled
disks.
When you add an Expansion Chassis to increase storage capacity, use the following
procedure:
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. Refer to instructions in the K2 System Guide.
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.)
