Conguring CMC
Chassis Management Controller enables you to congure properties, set up users, and alerts to perform remote management tasks.
Before you begin conguring the CMC, you must rst congure the CMC network settings to allow CMC to be managed remotely.
This initial conguration assigns the TCP/IP networking parameters that enable access to the CMC.
You can congure CMC using Web interface or Setting up Initial Access to CMC RACADM.
NOTE: When you congure CMC for the rst time, you must be logged in as root user to execute RACADM commands
on a remote system. Another user can be created with privileges to congure CMC.
After setting up the CMC and performing the basic congurations, you can do the following:
• Modify the network settings, if required.
• Congure interfaces to access CMC.
• Setup chassis groups, if required.
• Congure servers, I/O module, or front panel.
• Congure VLAN settings.
• Obtain the required certicates.
• Add and congure CMC users with privileges.
• Congure and enable e-mail alerts and SNMP traps.
• Set the power cap policy, if required.
• Add and congure storage sleds.
NOTE: The following characters cannot be used in the property strings of both the CMC interfaces (GUI and CLI):
• &#
• < and > together
• ; (semicolon)
Enabling or disabling DHCP for the CMC Network Interface Address
When enabled, the CMC’s DHCP for NIC address feature requests and obtains an IP address from the Dynamic Host Conguration
Protocol (DHCP) server automatically. This feature is disabled by default.
You can enable the DHCP to obtain an IP address from the DHCP server automatically.
Enabling or disabling DHCP for DNS IP addresses
By default, the CMC’s DHCP for DNS address feature is disabled. When enabled, this feature obtains the primary and secondary
DNS server addresses from the DHCP server. While using this feature, you do not have to congure static DNS server IP addresses.
To enable the DHCP for DNS address feature and specify the static preferred and alternate DNS server addresses, type:
racadm config -g cfgLanNetworking -o
cfgDNSServersFromDHCP 1
To enable the DHCP for DNS address feature for IPv6 and specify the static preferred and alternate DNS server addresses, type:
racadm config -g cfgIPv6LanNetworking -o
cfgIPv6DNSServersFromDHCP6 1
