Chapter 14 Administering and maintaining the K2 Storage System
application, add the clients that you removed in step 5 earlier in this procedure.
Refer to the K2 Media Client System Guide for specific procedures, 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.
14. Power up all K2 Media Clients and other iSCSI clients and test media access.
The replacing a server procedure is complete.
Replacing an iSCSI interface adapter (TOE card)
Prerequisites are as follows:
• The K2 Storage System must be at K2 system software version 3.2.7 or higher
before you begin this procedure.
• If the K2 Media Server has two single-port adapters and the replacement adapter is
a dual port adapter, you must remove both single-port adapters, even though only
one adapter is faulty, and replace them with the dual-port adapter.
To replace an iSCSI interface adapter on a K2 Media Server, do the following:
1. In the K2 System Configuration application, for the K2 Media Server with the
adapter or adapters you are replacing, open the iSCSI bridge page and identify the
ports on the adapter or adapters.
2. For the ports on the adapter or adapters you are replacing, make a note of the IP
addresses and subnet mask settings.
Later in this procedure you must assign these same settings to ports on the
replacement adapter.
3. Close the K2 System Configuration application.
4. Take the clients of the K2 Storage System offline and take all K2 Media Servers
out of service.
5. If you are replacing two single-port adapters with a dual-port adapter, uninstall K2
system software from the K2 Media Server.
6. Power down the K2 Media Server and replace the iSCSI interface adapter or
adapters. Refer to the service documentation on the Dell Documentation CD for
procedures. If you are replacing two single-port adapters with a dual-port adapter,
install the dual-port adapter in slot 2. Leave slot 3 empty.
7. Power up the K2 Media Server.
8. If you are replacing two single-port adapters with a dual-port adapter, install K2
system software (version 3.2.7 or higher is required) on the K2 Media Server and
then restart the K2 Media Server.
9. In the K2 System Configuration application, open the iSCSI bridge page for that
K2 Media Server. It displays iSCSI interface adapters on the K2 Media Server,
identified by MAC address. Notice that on replacement adapter ports the MAC
address is different than it was on the former adapter, the IP addresses is set to
0.0.0.0, and bandwidth subscription set to 0.
