Dell DX6000 Manual de iniciação
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

4.2.4. Administration Password

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.

4.3. Booting DX Storage Nodes

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.
