V20z or V40z Discovery Fails With Error Cannot Open IPMI Session

Discovery cannot open an IPMI session to a Sun Fire V20z or a V40z server if the IPMI password on the V20z or V40z is missing or has been reset.

To reset the IPMI password and then discover the server, proceed as follows:

1. Open a terminal window and log in to the V20z or V40z service processor admin account using SSH.

2. Type the command ipmi get channels followed by the command ipmi reset -a to reset the IPMI password. You are prompted to confirm the new password.

   For example, assume the server management processor IP address is 10.0.5.3, and that the default ssh account name admin and the default password admin have not been changed:

   bash-3.00# ssh -l admin 10.0.5.3 admin@10.0.5.3's password: Sun Microsystems IPMI v2.0 Service Processor Version: V2.4.0.6 localhost $ localhost $ ipmi get channels Channel Status lan enabled sms enabled localhost $ ipmi reset -a localhost $ localhost $ ipmi enable channel lan Password: example Confirm password: example

3. Rerun discovery from the N1 System Manager commandline interface for the V20z or V40z, using the IPMI password you specified.

For example:

N1-ok > discover 10.0.5.3 ssh=admin/admin ipmi=/example
