Chapter 12 Administering and maintaining the K2 SAN
Accessing a K2 SAN from multiple PCs
It is recommended that you install the SiteConfig application and the K2 System
Configuration (K2Config) application on one PC only in your facility. This eliminates
potential problems in the installation, configuration, and maintenance of your K2
SAN.
If you run SiteConfig and/or K2Config on multiple PCs in your facility, you must
enforce an operational policy whereby you constrain your use of the applications as
follows:
• Designate a control point PC as the configuration PC and then make changes from
that PC only.
• On the other control point PCs, limit operations to view-only when accessing the
K2 SAN. Do not make changes. With K2Config there is some basic protection, in
that the first instance of the application in essence “locks out” any other instances.
However, SiteConfig has no such protection and making changes on devices from
multiple SiteConfig instances can result in configuration and software deployment
errors.
SiteConfig has no features that are designed to support access from multiple
instances. If you access systems from multiple instances of SiteConfig, you must
define and enforce your own policy. For example, you can import system descriptions
or otherwise create systems and discover devices in each instance of SiteConfig and
then enforce policy whereby instances are kept in synch.
In K2Config, to access a K2 SAN from multiple control point PCs, do the following:
1. Install Control Point software on the designated K2 System Configuration control
point PC and complete the initial system configuration. Close K2Config on that
PC.
2. Install Control Point software on another control point PC and open the K2Config.
3. Select Retrieve Configuration and enter the name or IP address of the K2 Media
Server for the K2 SAN. If the K2 SAN has multiple K2 Media Servers, you must
enter the name or IP address of the server configured first.
If there is another instance of the K2Config on a different control point PC
currently accessing the K2 SAN, a message informs you of this and you are not
allowed to access the system.
If access is allowed, a Retrieving Configuration message box shows progress. It
can take over 30 seconds to retrieve the configuration. When the configuration is
retrieved, the K2 SAN appears in the tree view. Make sure that you only attempt
view-only operations from this PC. Do not configure the K2 SAN from this PC.
4. Repeat the previous steps for other control point PCs from which you need access
to the K2 SAN.
When you expand and select nodes in the tree view to view K2 SANs, individual
devices, and configuration settings, K2Config displays information as found in a
configuration file, rather than continuously polling devices to get their latest
information. The configuration file is saved on the V: drive, along with the media files
in the shared storage system. When you use the Retrieve Configuration feature, you
are connecting to the configuration file.
