64-bit OS
Do these checks before you update your system to 11i.
After Updating to 11i: To achieve the same results as with the obsolete
monitors, use the EMS Hardware Monitors on the updated system. See
the EMS Hardware Monitors User's Guide available at:
docs.hp.com/hpux/diag/
FYI: As of the February 1999 release of the hardware diagnostics, there
has been a change to the way monitoring is done for disc30, sdisk and the
HA Disk Array Models 10, 20, and 30FC. Formerly, the diaglogd exec
programs (pdisc30_exec, pharaymon_exec, and psdisk_exec) handled
driver error entries for these devices. As of the February 1999 release,
these programs have been deleted and their functionality is now
provided by the EMS Hardware Monitors.
On systems with a floppy-disk drive attached, hardware information will
not be captured in the System Configuration Repository (SCR) under 11i.
After updating a system with a floppy drive from 10.20 to 11i, you will
find a core file in /usr/dmi/bin, and hpuxci (HP-UX DMI Component
Instrumentation) will not be running.
This problem affects you if there is a floppy drive attached to (or installed
in) your system, and you use the System Configuration Repository (SCR)
to store hardware information. Since the hpuxci is not running,
hardware information will not be captured. The problem occurs if
/dev/floppy exists.
A fix for the problem will be made available in the earliest follow-up
patch release for 11i. In the meantime, if you depend on the SCR, you
should either not update to 11i, or remove the floppy drive.
FYI: If /dev/floppy exists, hpuxci sets default attributes for the device.
The code that does this does not null-terminate the string passed to atoi()
which results in a segfault (segmentation fault). The fix for this will
terminate the string correctly.
EISA I/O drivers for TermIO, FDDI, 100BT and Token Ring cards are
supported on HP-UX 32-bit OS, but not 64-bit OS. You will not see an
error or warning message stating that these EISA products will not work
after installing or updating to 64-bit OS.
