HP Tru64 UNIX and TruCluster Server Version 5.1.B-4 Patch Summary and Release Notes (13156)

# 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.
3.2.2.23.2 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.
3.2.2.23.3 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.
# hwmgr -offline -name cpuN
If, for example, the codconfig command returns the message "Error for CPU 2: Unable to offline
this CPU," you would enter the following hwmgr command:
# hwmgr -offline -name cpu2
For more information, see codconfig(8) and hwmgr(8).
The Manage CPUs suitlet is available from the SysMan Menu and SysMan Station.
