Update Fails if nstrpty
Kernel Parameter Set
as a Formula
If the value of the nstrpty kernel parameter is specified as a
formula (for example, nstrpty (NPTY*2)), then updating to
HP-UX 11i will fail with this error:
/var/tmp/BAAa10554/catalog/Streams-TIO/STRTIO-KRN/posti
nstall[82]: (NPTY):
The specified number is not valid for this command.
ERROR: The “postinstall” script for
“Streams-TIO.STRTIO-KRN” failed (exit code “1”).
The script location was
“/var/tmp/BAAa10554/catalog/Streams-TIO/STRTIO-KRN/post
install”.
To prevent this, convert the value of nstrpty to a number.
To check the kernel parameters, run SAM and select:
Kernel
Configuration
-> Configurable Parameters
If the nstrpty kernel parameter is specified as a formula,
then before you update, use SAM (
Kernel Configuration ->
Configurable Parameters) to change the formula to a numeric
value. You do not need to rebuild the kernel or reboot the
system.
