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 11i will fail with this
error:
/var/tmp/BAAa10554/catalog/Streams-TIO/STRTIO-KRN/postinstall[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/postinstall”.
To prevent this, convert the value of nstrpty to a number.
How Do You Know
If This Affects
You?
To check the kernel parameters, run SAM and select: Kernel Configuration
-> Configurable Parameters
What To Do 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.
Kernel Build Failure
When updating a workstation running on a HP-UX 10.20 32-bit OS to
11i 32-bit OS/OE, the update may fail if a USB driver is configured on
the system. This will not occur when updating to 11i 64-bit OS.
If this occurs, update-ux displays this message on the console before
quitting:
Loading the kernel...
/usr/ccs/bin/ld: Unsatisfied symbols:
wsio_get_service (code)
Stop...
ERROR: The kernel build failed...
