Grass Valley K2 Summit Storage Area Network Installation - Manual (Page 293)

1. If the server hosts an iSCSI interface adapter, copy down iSCSI bandwidth settings for K2 clients
and other iSCSI clients that use the faulty server as their iSCSI target, as follows:
a) In the K2Config application, select the K2 SAN in the tree view and then click the button in
the toolbar to view client iSCSI assignments. A page opens that displays each client’s primary
and secondary iSCSI targets.
b) In the tree view, select one of the clients that have the faulty server as a primary or secondary
iSCSI target.
c) Open the client’s iSCSI Initiator Configuration page and click Modify . The Bandwidth Input
dialog box opens.
d) Copy down the bandwidth settings configured for that client and then close the Bandwidth
Input dialog box.
e) Repeat these steps for each client that has the faulty server as a primary or secondary iSCSI
target.
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.
