44 Disaster Recovery
NOTE: Network switch configuration is outside the scope of the DX Cluster
Services Node software. Switches must be properly configured by a system
administrator to ensure correct connectivity and bonding mode support.
Administrators must not connect the configured internal network ports to the
external network.
Connecting the DX Cluster Services Node to the
Private and Public Networks
• Connect the lower NIC ports 0-1 of the DX Cluster Services Node to the
external private network switch.
• Connect the upper NIC ports 2-3 of the DX Cluster Services Node to the
internal network switch.
Connecting the DX Storage Nodes to the Private
Network
Connect all the NIC ports (LOM as well as add on card, if available) of each
storage node to the internal private network switch.
NOTE: Do not turn on the storage nodes at this time.
Creating a Local YUM Repository on the DX6000
System
The DX Cluster Services Node software installation process is dependent on
additional rpm packages that are not installed on the systems by default.
These packages are available on the Red Hat Enterprise Linux distribution
media included with the system. A local YUM repository is required to update
the system with the package dependencies for the DX Cluster Services Node
software installation.
To create a local YUM repository on your system:
1
Turn on the DX Cluster Services Node.
2 Insert the operating system media that came with the system into the
optical drive and allow the file system to auto mount. The default
directory path for the auto mounted file system is
/media/RHELx.x\
