blank getconf

[someone_4]

Hello all

for some reason my getconf MACHINE_SERIAL comes back blank on a couple of servers.

# getconf MACHINE_SERIAL

# getconf KERNEL_BITS
64
# getconf HW_32_64_CAPABLE
1
# getconf POSIX_VERSION
199009
# getconf MACHINE_SERIAL

#


# ll /usr/bin/getconf
-r-xr-xr-x 1 bin bin 98304 Nov 14 2000 /usr/bin/getconf

The size and date seems fine on a system that doesnt work and one that does.

I can't figure out what would cause this.
Any ideas?

thanks
Richard

I made a backup of getconf and copied a "working" getconf over and I still get blanks.

echo "sel path system\ninfolog\nexit"|cstm|grep "System Serial Number"

Does work!

After firmware updgrade sometimes serial is missing. To add it contact your local HP suport engineer - there is procedure for entering new serial.

Reading the serial number is a recent feature on new hardware. Older machines will report nothing in response to getconf MACHINE_SERIAL as they have no CPU-based serial number (example: K-class, D-class, etc). As mentioned, a blank serial number can be due to a repaired CPU board which was not configued correctly.
