When using the all keyword, DX Storage automatically excludes the DX Storage USB flash drive

from being used for storage.

To explicitly set the disk device names, set vols to a space-separated list of drive identifiers. DX

Storage uses standard Linux volume identifiers like /dev/sda, /dev/sdb, and so on. If you are

not sure what your volume identifiers are, you can access the DX Storage node using another Linux

system.

Using the preceding example, set vols to:

vols = /dev/sda /dev/sdb

For more information about the Admin Console, see the DX Object Storage Administration Guide.

Warning

After performing the tasks discussed in this section, you must make sure that no one

(including your IT personnel and any on-site contractors) boots a non-DX Storage system

from this USB flash drive. If a computer is accidentally booted from a configured USB

flash drive, some or all of its disks could be reformatted, leading to permanent data loss.

4.2.3. DHCP or Static Network

The simplest way to set up your cluster is using DHCP to automatically administer nodes' IP

addresses. DHCP is default when using a CSN; otherwise, you need a DHCP server in the network

in which the nodes are located. No other configuration is required and DX Storage is ready to be

booted from the USB flash drive or network boot environment.

To use static IP addresses for DX Storage nodes, edit the following parameters in the node and/

or centralized configuration files: ipaddress, netmask, and gateway. All three parameters

must be set when using the static IP address configuration option. In a centralized configuration

environment, the status IP address configuration must be set in a custom configuration file per node

because this information cannot be shared among nodes. An example follows:

ipaddress = 10.20.30.101

netmask = 255.255.255.0

gateway = 10.20.30.1

DX Storage nodes require an administration password for making changes using the Admin

Console or to perform SNMP operations on a node. You should change the default password

when you deploy DX Storage. You should also encrypt the password to make it more secure. The

administrators parameter in node.cfg defines administrator user names and passwords.

See the DX Object Storage Administration Guide for additional details on using the administrators

parameter and the CSN Installation and Configuration Guide for details on editing administrators

from the CSN Console.

After either completing all basic configuration for a USB flash drive boot configuration and inserting

the USB flash devices into a DX Storage nodes or making the network boot environment is

configured and available, you can power up your DX Storage nodes.

Attaching a monitor to the node is optional.
