Important: IPMI on a Public LAN can be a major security liability providing anyone with the proper credentials direct hardware and console level access to your server. Please use good security practices when implementing IPMI access.

Outlines how to configure IPMI on K-144T and K-168T nodes
- IPMI port location
- Verify IPMI LAN Configuration
- IPMI LAN Configuration with static IPs
- IPMI User Operations
- Connect via IPMI
Note: You can use the following IPMI Instructions for K-144T or K-168T nodes. For other platforms, see:
- IPMI Quick Reference Guide for QC24 (Gen1)
- IPMI Quick Reference Guide for Qumulo C-Series
- IPMI Quick Reference Guide
- K-144T or K-168T platform
- Root user access via ssh on the client facing network
Note: To access the IPMI CLI while physically connected to the node, press CTRL+ALT+F1.
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 account & password is ADMIN/ADMIN all uppercase
Note that this account name and password are completely independent of your Qumulo root/admin password
The instructions provided below have to be entered into each node that will be a member of your IPMI maintenance network.
IPMI Port Location
Verify IPMI LAN Configuration
- Use the following command:
# 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 default ADMIN password
# ipmitool user set password 3 Password for user 3: Password for user 3:
- Create new user
- Example: Create Admin user “netadmin” in 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 via IPMI
Once configuration is complete, accessing the nodes via 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.
If you cannot connect to the IPMI management console and you are sure that your network configuration is correct, reset the BMC via a SSH or KVM Console session to the node in question:
# ipmitool bmc reset cold
