prtdiag -v Voltage Indicators Section Has Non-Voltage
Indicators (CR 6587380)
Non-voltage indicators (such as PS0/TEMP_FAULT) will appear under the Voltage
Indicators section of the prtdiag output. The information reported under the
condition column is accurate and represents the current condition of the
components.
prtdiag -v Slow To Respond on 1U (CR 6588550)
The prtdiag -v command is slow and could thus appear to hang. It could take up
to five minutes for the command to complete.
Control-C from prtdiag, Blank Environmental Data Fields
When Run Again (CR 6552999)
When the verbose (-v) option is specified to the prtdiag command in the control
domain, additional environmental status information is displayed. If the output of
this information is interrupted by issuing a Control-C, the picld(1M) daemon may
enter a state that prevents it from supplying the environmental status information to
prtdiag
from that point onward, and the additional environmental data will no
longer be displayed.
Workaround: Restart the picld SMF service in the control domain with the
following command:
-> set /SYS/LOCATE value=off
OR
-> set /SYS/LOCATE value=Fast_Blink
# svcadm restart picl
