Can not find a valid IPMI device

To clarify are you using ipmicfg to change the IPMI password on the Hyper-V host?

Our IPMI password document (https://portal.nutanix.com/#/page/docs/details?targetId=Hardware_Administration_Reference-NOS_v4_1:har_password_change_ipmi_t.html) covers changing the IPMI password through Hyper-V shell:

1. Log into the Hyper-V host with SSH.
2. Determine the user ID of the administrator for which you want to change the password.> ipmiutil user list A sample output is as follows. ID Name Callin Link Auth IPMI Msg Channel Priv Limit2 ADMIN true false false Unknown (0x00)In the sample output, the ID of the administrator for which you want to change the password is 2.
3. Set the new password.> ipmiutil user set password user_id new_password

For example "ipmiutil user set password 2 NEWPASS" for the sample output.



Also make sure to update the IPMI password in Zeus config:

• Update the administrative user password for all hosts in the Zeus configuration.[list=1]
• Log on to any Controller VM in the cluster with SSH.
• Generate a list of all hosts in the cluster.nutanix@cvm$ ncli -p 'admin_password' host list | grep -E 'ID|IPMI Address'Note the host ID of each entry in the list.
• Update the IPMI password.nutanix@cvm$ ncli -p 'admin_password' host edit id=host_id ipmi-password='ipmi_password'[list]
• Replace admin_password with the Prism password for the admin user.
• Replace host_id with a host ID you determined in the preceding step.
• Replace ipmi_password with the administrative user password on the corresponding IPMI host.

Perform this step for every IPMI host in the cluster.

If you have the current IPMI password (default username:password ADMIN:ADMIN) the easiest way to change the password is through the GUI:

• Change the administrative user password of all IPMI hosts.Perform these steps on every IPMI host in the cluster. [list=1]
• Sign in to the IPMI web interface as the administrative user.
• Click Configuration.
• Click Users.
• Select the administrative user and then click Modify User.
• Type the new password in both text fields and then click Modify.
• Click OK to close the confirmation window.

You will still need to follow the procedure to update the IPMI password in Zeus config after updating the password in the GUI.
