6. When the Unlocking Devices window reports that the unlock process completed successfully,

Take SAN clients offline
When upgrading software on a K2 SAN, you upgrade software on K2 Media Servers before you
upgrade software on the connected SAN clients. This includes K2 clients, K2 appliances, Aurora
clients, and generic clients. While you are upgrading software on K2 Media Servers you must keep
all connected client devices of ine (all media access stopped) or shut down. Do not power up or
start media access on connected devices until the upgrade on K2 Media Servers is complete and the
media le system/database server is fully operational.
1. If you have not already done so, stop all media access on SAN clients. This includes all record,
play, and transfer operations
2. For K2 Summit Production Clients, if you have not already done so, disable (unlock) the write
lter.
3. Shutdown all the SAN K2 clients on the SAN. To do this in SiteCon g, right-click a client device
in the tree view and select
Next upgrade K2 Media Servers. If you have multiple K2 Media Servers you must manage them
properly for the upgrade process.
Manage multiple K2 Media Servers
Do not do this task if:
You are upgrading a K2 SAN with only one K2 Media Server. Skip ahead and begin upgrading
your K2 Media Server.
Do this task if:
You are upgrading a basic (non-redundant) K2 SAN with multiple servers. This means you have
just one K2 Media Server that takes the role of media le system/database server and one or
more other K2 Media Servers dedicated to other roles, such as FTP server.
You are upgrading a redundant K2 SAN. This means you have two K2 Media Servers (primary
and backup) that take the role of media le system/database server.
NOTE: If the K2 SAN has multiple K2 Media Servers, you must upgrade all to the same version.
If you are upgrading a basic K2 SAN with multiple servers:
1. Upgrade the server that takes the role of media le system/database server rst.
2. After the media le system/database server is upgraded and when instructed to do so in a later
task, upgrade your other servers.
If you are upgrading a redundant K2 SAN:
Use the following steps to manage primary/backup roles and upgrade your two media le
system/database servers in the proper sequence. This avoids triggering a failover event.
