Update Known Problems
Appendix B176
• swinstall errors:
/var/adm/sw/swinstall.log and /var/adm/sw/swagent.log
SD commands log errors to /var/adm/sw/swagent.log, plus their own
log. Simply checking more than one log file may reveal the problem you
are troubleshooting.
Update Fails on J2250 Workstation With SCSI Floppy
Drive
See “Kernel Build Fails on 64-bit Install” on page 168.
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.
