IPMI Quick Reference Guide for C-72T, C-168T, C-192T, C-432T, and K-432T Nodes

IMPORTANT: Access to the out-of-bound management (IPMI) port on a public LAN can have serious security implications because it can grant anyone with credentials direct access to your server's hardware and console. Follow security best practices when implementing IPMI access.

IN THIS ARTICLE

This article outlines how you can configure IPMI on C-72T, C-168T, C-192T, C-432T, and K-432T nodes.

Note: For more information about other platforms, see the following resources:

REQUIREMENTS

Root user access through ssh on the client-facing network, for example:

sudo -s

Note: To access the IPMI CLI while physically connected to the node, press CTRL+ALT+F1.

DETAILS

Qumulo node motherboards provide IPMI support which allow for off-band maintenance access even if the node is turned off when plugged into power.

  • Nodes are configured to receive DHCP address assignments by default
  • The IPMI access network can be completely separate from your client facing network

  • The default IPMI username and password are ADMIN.

    • Note that this account name and password are completely independent of your Qumulo root or administrator password

The instructions provided below have to be entered into each node that will be a member of your IPMI maintenance network.

Verify IPMI LAN Configuration

# ipmitool lan print 1

IPMI LAN Configuration with Static IPs

# ipmitool lan set 1 ipsrc static #Set IPMI ethernet interface to static IP
# ipmitool lan set 1 ipaddr XXX.XXX.XXX.XXX #Set the IP address of the interface
# ipmitool lan set 1 netmask 255.XXX.XXX.XXX #Set the Subnet Mask for the interface
# ipmitool lan set 1 defgw ipaddr XXX.XXX.XXX.XXX #Set the IP address of the Default Gateway
# ipmitool lan set 1 arp respond on #(Optional) Enable BMC ARP responses

IPMI User Operation Examples

  • List current users 
# ipmitool user list 1
ID Name Callin Link Auth IPMI Msg Channel Priv Limit
1 false false true ADMINISTRATOR
2 root false true true ADMINISTRATOR
  • Change the default ADMIN password.
# ipmitool user set password 3
Password for user 3:
Password for user 3:
  • Create new user
    • Example: Create administrative user netadmin on user slot 4.
# ipmitool user set name 4 netadmin
# ipmitool user set password 4
Password for user 4:
Password for user 4:
  • Set user access
# ipmitool channel setaccess 1 4 link=on ipmi=on callin=on privilege=4
# ipmitool channel setaccess 2 4 link=on ipmi=on callin=on privilege=4
# ipmitool user enable 4
  • Verify User Level Access
# ipmitool channel getaccess 1 4 
Maximum User IDs : 10
Enabled User IDs : 4
User ID : 4
User Name : ADMIN
Fixed Name : No
Access Available : call-in / callback
Link Authentication : disabled
IPMI Messaging : enabled
Privilege Level : ADMINISTRATOR

Connect to Nodes through IPMI

Once configuration is complete, accessing the nodes through IPMI requires a Java-capable web browser using the IPs assigned by you or your DHCP server as outlined below. Use Firefox or Chrome for best results.

Troubleshooting

If you cannot connect to the IPMI management console and you are sure that your network configuration is correct, reset the BMC through a SSH or KVM Console session to the node in question:

# ipmitool bmc reset cold
