New Attention Indicator Behavior
updated for
September 2001
The fruled command and Partition Manager now blink the attention indicators (LEDs)
on HP Superdome cells and I/O chassis rather than illuminating them in a steady-on
state, as was the case with the original 11i release.
Likewise, on HP rp8400 servers, the fruled command and Partition Manager behaviors
are to blink cell attention indicators. (HP rp8400 servers do not provide user-controllable
I/O chassis or cabinet-level attention indicators.)
In addition, the SAM (/usr/sbin/sam) and Partition Manager utilities now blink PCI
slot attention LEDs for procedures that involve locating PCI slots. Both HP Superdome
and HP rp8400 servers support this PCI slot attention indicator usage.
For example, the fruled -o -c2 command now causes cell 2’s attention indicator to
blink. On HP Superdome servers, the fruled -o -i0/1/3 command blinks the
attention indicator for cabinet 0, I/O bay 1, chassis 3.
The /usr/sbin/rad command still provides the same functionality for managing PCI
card slot attention indicators. You shoulduse the rad -f attention #-#-#-# command
to blink the attention LED when locating the specified slot ( #-#-#-# ). See rad (1M) for
options.
Benefits
These changes conform to the PCI Hot-Plug specifications for attention indicator states
and meanings, as detailed in the following table:
Impact
These changes affect all current HP hard-partitionable servers (including HP rp8400
servers and all HP Superdome models), and will be implemented for all future HP
hard-partitionable servers, as well. (HP rp8400 servers were never supported by HP-UX
releases with the old behavior.)
