HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

If your firmware is lower than V6.4-12, the problem is experienced if one or both of the
following conditions exists:
• The system manager uses the following hwmgr utility commands:
# hwmgr -view devices
# hwmgr -view hierarchy
• The Environmental Monitoring daemon, envmond, is running.
As a workaround to the problem, you can modify one of the following two files and
then reboot your system for the new setting to take effect:
• /etc/rc.config
Turn off environmental monitoring by changing the entry ENVMON_CONFIGURED=1
to ENVMON_CONFIGURED=0
You can also use the envconfig utility to modify the /etc/rc.config file.
See envconfig(8) for information.
• /etc/sysconfigtab
At the end of the file, add the following line:
marvel_srvmgmt: MV_Env_Support = 0
You must remove this setting after you install firmware V6.4-11 or higher.
3.2.2.30.2 CPU Offline Restrictions
The Primary CPU cannot be taken off line.
CPUs that have I/O hoses attached to them can only be taken off line if another CPU
without I/O attached is present in the system . A failure to adhere to this restriction
will cause the psradm command to return an error.
In a two-CPU configuration, the AlphaServer ES47 and ES80 do not allow any CPUs
to be taken off line.
3.2.2.30.3 Problem with Capacity-on-Demand Process
A problem has been discovered with the capacity on demand process in which a CPU
can be designated as spare, but is not taken off line as expected.
With the capacity-on-demand process, the codconfig [cpu_id_list] command
lets you specify which CPUs you have paid for and which are spares. The command
is supposed to mark the others as spare and then take them off line. Once a CPU is
marked as spare, the hwmgr command and Manage CPUs suitlet will not let you put
them on line until you use the ccod -l or ccod -p command to either loan or
purchase the CPU.
The workaround is to use the codconfig [cpu_id_list] command to mark the
CPUs as spare, and then use either the hwmgr command or the Manage CPUs suitlet
to take them off line (sometimes referred to as offlining them). In the following example,
N is the CPU number.
