6 Create the /u01 directory in root directory and mount the file system to
the
/u01 directory. For example, run the following command:
mkdir /u01
mount /dev/sdb1 /u01

To keep the mount path persistent across reboot, add the mount path to
/etc/fstab . For example, run the following command:
vi /etc/fstab
Table 5-2 lists the options that must be selected to create a mount path.
Reinstalling the DX Cluster Services Node
Software
Setting Up and Configuring the Network
The DX Cluster Services Node software requires access to both the external
network and to a dedicated internal network. The internal private network
ensures that the DX Storage Cluster traffic is protected from unauthorized
access and that the external network is isolated from both the PXE boot
server and cluster multicast traffic. The DX Cluster Services Node software
automatically allocates the first half of the Ethernet ports detected on each
NIC interface card to the external network and the second half of the
Ethernet ports detected on each NIC interface card to the internal network.
All NICs allocated to a network are bonded into a bond interface using
mode 6 or balance alb bonding. For example, on a server with four LOM ports
and a quad port NIC adapter, LOM ports 0-1 and NIC adapter ports 0-1 are
allocated to the external network in a balance-alb bond interface and LOM
ports 2-3 and NIC adapter ports 2-3 are allocated to the internal network in a
balance-alb bond interface.
