Selecting a Host IP Address on Systems with Multiple IP
Addresses
During installations where multiple IP addresses exist on a host (i.e. multiple
LAN cards in a single host), only one of the IP address will be entered into the
/etc/opt/sanmgr/hostagent/config/commIpAddr.txt file. If this is not the
correct address, the hostagent will not communicate with the array.
After installation, check the contents of the /etc/opt/sanmgr/hostagent/
config/commIpAddr.txt file. If the correct IP address is not shown, manually
enter the correct IP address.
Please restart the host agent service, if ‘commIpAddr.txt’ file is manually
modified.
Changing Thread Count
The Command View SDM server components run within the context of a single
instance of the Java Virtual Machine. In HP-UX this is a single process. Within
the Command View server instance of the JVM, multiple threads of execution
are running virtually concurrently. By default, a single process is limited to 64
threads. If the process attempts to spawn more threads, an
Out of Memory
error may be reported.
To avoid this situation, the thread count should be increased by setting the
following kernel parameters:
max_thread_proc set to at least 256
nkthread set to twice the value of max_thread_proc
To determine the current values of these parameters run:
#kmtune | grep -e max_thread_proc -e nkthread
After these settings have been changed, rebuild and reboot into the new
kernel.
Note Changing the thread count settings is only necessary if you
observe
Out of Memory errors when running Command View.
