Determining Hardware Power Status [HP-UX]
This procedure (parstatus -B, parstatus -V -b # , frupower -d -C,
frupower -d -I, or rad -q) checks the power status for system
hardware from HP-UX.
For details on these HP-UX commands, see the online manpages for
parstatus (1M), frupower (1M), and rad (1M).
Step 1. Login to HP-UX running on one of the system’s nPartitions.
To check the power status for PCI card slots, you must login to the local
nPartition where their PCI card cage resides.
You can check the power status for cabinets, cells, and I/O chassis from
any nPartition.
Step 2. Issue the HP-UX commands to check the power status for the system
components of interest to you.
• Cabinet Power—Use the parstatus -V -b # command to check
cabinet power status for the specified cabinet (-b # ), or use the
parstatus -B command for brief power status for all cabinets.
The parstatus command gives details about each cabinet’s bulk
power supplies and power boards, as well as details about cabinet
fans and blowers.
• Cell Power—Use the frupower -d -C command to list cell power
status for all cells, or use the frupower -d -c # command to list
power status for a specific cell ( -c # ).
• I/O Chassis Power—Use the frupower -d -I command for power
status for all I/O chassis, or use the use frupower -d -i #/#/#
command to list details for a specific I/O chassis
( cabinet/bay/chassis )
• PCI Card Slot Power—Use the rad -q command and option to list
details including PCI card slot power for all PCI card slots within the
local nPartition.
The rad command lists information for the local nPartition only.
The following example output shows power details for an HP Superdome
system’s cabinet, cells, I/O chassis, and PCI slots, as presented by
various HP-UX commands.
