Symptoms
Customer wants to remove unwanted aliases from the NVRAM; OBP document said to run "nvunalias" then "reset-all". This did not give any complaints, but when custormer ran "devalias" the entries were still there. This causes confusion among Systems Administrators at customer site. This is not a bug, but occurs because the NVRAM retains all the aliases "names" once set. How do you clear them permanently?

Resolution
When running the nvunalias and reset-all commands do not clear out an unwanted alias, use the following procedure:

1) Save all aliases that you want from the NVRAM. Be sure to include any macros; for example, in cluster environment, there is setting for multi SCSI initiator. If the OBP has "use-nvramrc? true" then you have it set.

2) OK> set-defaults

Clear all settings to default values.

3) OK> setenv auto-boot? false

After the reset it puts you back to the OBP level so you can set your aliases, nvramrc, etc.

4) OK> reset-all

5) After the reset-all, it will put you at OBP, set your aliases from the values saved in step-1.

6) OK> reset
Verify that all your settings stick and that the unwanted aliases are gone.
