After reseating PS1 on Sun Fire[TM] V1280 running Solaris[TM] 9, voltage sensors on PS1 no longer appear in prtdiag output.

Moreover, if PS2 is subsequently reseated, PS2 voltage sensors no longer appear, while PS1's sensors reappear.

Resolution
It appears that the the Platform Information and Control Library daemon (picld) does not receive updates from the System Controller when the power supplies are reseated.
To resolve this issue, install prtdiag Patch ID: 113447-25 or higher.

Relief/Workaround
The workaround is to restart picld.

- /etc/init.d/picld stop
- /etc/init.d/picld start

After restarting, picld will take up to 10 minutes to re-synchronize with the hardware. Then, the power supplies voltage sensors appear in the prtdiag output.
