HP Tru64 UNIX Technical Updates for the Version 5.1B and Higher Operating System and Patches (February 2010)

Potential False Temperature Error Condition on AlphaServer DS10, DS10L, and TS10
Systems (Feb. 2004)
A sensor error can potentially indicate a false over-temperature condition on AlphaServer DS10,
DS10L, and TS10 systems. While the sensor accurately reports the temperature, it falsely reports
the high temperature threshold. This false reporting of the threshold value can cause the Insight
Management SMP Agents to forward false traps, and potentially result in the Tru64 UNIX
environmental monitoring daemon (envmond(8)) initiating the shutdown process. However,
this false reporting condition is temporary and the high temperature threshold soon returns to
normal, at which point the shutdown is cancelled.
To work around this problem, use the envconfig utility to manually set the high temperature
threshold to its current default value. While this does not change the value, the act of setting it
manually forces envmond to use the manually applied value. Once manually set, the
ENVMON_HIGH_THRESH variable persists in the /etc/rc.config database. This will
permanently work around the issue for current and future envmond sessions. To manually set
the variable, follow these steps:
1. Determine the the value of ENVMON_HIGH_THRESH:
# sysconfig -q envmon | grep thresh
# env_high_temp_thresh = 60
2. Manually set the threshold value using the envconfig utility:
# envconfig -c ENVMON_HIGH_THRESH=60
Increasing PCI Box Support on GS1280 M32 to 16 (Aug. 2003)
The maximum number of standard I/O hoses (IDE buses) allowed for an initial install of Tru64
UNIX Version 5.1B from the CD-ROM is eight. Any I/O drawer connected to a hose that has
more than eight must be disconnected or powered down during a fresh install from the Tru64
UNIX CD-ROM.
Console Error in the XP1000 Workstation (Aug. 2003)
There is a console error on XP1000 workstations that prevents you from using IDE CD-ROMs
attached to the secondary port as boot devices. The secondary IDE devices are seen at the console
on the XP1000 as follows:
Primary IDE devices that you can boot from:
dqa0.0.0.207.0 (master primary)
dqa1.1.0.207.0 (slave primary)
Secondary IE devices that you cannot boot from:
dqb0.0.1.207.0 (master secondary)
dqb1.1.1.207.0 (slave secondary)
There is no problem in using the IDE devices on the secondary port once the system is set up,
but you cannot boot from them.
General and Problem Information for AlphaServer ES47, ES80, and GS1280 Systems
(Jan. 2003)
The following information pertains to the new AlphaServer ES47, ES80, and GS1280 systems,
which require Tru64 UNIX Version 5.1B and Patch Kit 1 to be installed.
Time Loss (March 2003)
During some operations of the Environmental Monitoring daemon, and the use of some hwmgr
commands, these systems may experience time loss. This time loss is caused by problems with
the console callbacks for environmental information.
