2. If the server hosts an iSCSI interface adapter, in the K2 System Configuration application, for
the faulty K2 Media Server, open the iSCSI bridge page and make a note of the IP addresses.
3. Copy down network and hostname settings for the faulty K2 Media Server. You can do this from
SiteConfig or from the K2Config application Network Configuration page.
4. Save a copy of the host table from the faulty K2 Media Server. You can use SiteConfig hosts
file features or you can find the host table at the following location on the K2 Media Server:
C:\WINDOWS\system32\drivers\etc\hosts
5. If the server hosts an iSCSI interface adapter, in the K2Config application, remove the K2 clients
and other iSCSI clients that use the faulty server as their iSCSI target, as determined earlier in
this procedure.
6. Stop all media access and power down all K2 clients and other iSCSI clients.
7. If the faulty server is a media file system/metadata server, take the K2 Media Server out of
service. If it is a redundant server, it must be the backup before you take it out of service.
8. In the K2Config application, remove the faulty K2 Media Server as follows:
a) In the tree view, select the K2 Media Server
b) Click
Remove
and
Yes
to confirm. The K2 Media Server is removed from the tree view.
9. In SiteConfig, remove the K2 Media Server.
10. Physically remove the faulty K2 Media Server and put the replacement server in its place.
Reconnect all cables to the replacement server as they were to the faulty server.
NOTE: If the replacement server was previously configured on a K2 SAN, you must restart
it before adding it to a K2 SAN or in any other way reconfiguring it for use.
11. In SiteConfig, add, discover, and assign the replacement server. Configure the hostname and all
network settings on the replacement server to be the same as they were on the faulty server.
12. Copy the host table onto the replacement server. You can use SiteConfig for this task.
13. In the K2Config application, add and configure the replacement server. Refer to the installation
chapter for the level of your system earlier in this manual for specific procedures, with the
following special instructions:
a) Add the server to the K2 SAN, using the
Add Device
button.
b) Configure the replacement server so that its settings are all the same as they were on the faulty
server.
• On the Define Server Roles page, assign the same roles.
• On the Network Configuration page, verify the same network settings for the FTP network.
• If the server hosts an iSCSI interface adapter, on the iSCSI Bridge Server Configuration
page, verify the same settings.
c) After completing the configuration, restart the machine to put changes into effect.
14. If the server hosts an iSCSI interface adapter, in the K2 System Configuration application, add
the clients that you removed in step 5 earlier in this procedure, with the following special
instructions:
a) Add the client with the highest iSCSI bandwidth first.
b) On each client, configure iSCSI bandwidth settings so they are the same as they were before.
15. Power up all K2 clients and other iSCSI clients and test media access.
