Changing the Server Name and the IP Address

• Using set_parms  --> may not work correctly for multiple nics
• set_parms hostname  ( a reboot is required for the change to take effect)
• It will prompt you for the new hostname
• It will prompt you to reboot (answer no if you are also changing the ip address)
• set_parms ip_address   ( a reboot is required for the change to take effect)
• It will prompt you for the new ip address
• It will prompt you to reboot
• Manually makiing the change:
• vi /etc/hosts
• vi /etc/rc.config.d/netconf   <-- ** Make sure that no extra files are in the /etc/rc.config.d directory - it gets sourced on bootup
• reboot
• Other files that may need to checked/changed
• /etc/resolv.conf
• /etc/nsswitch.conf

System Tuning

Extract Current System File

• cd /stand/build
• /usr/lbin/sysadm/system_prep -s /stand/build/system
• file is called system
• section called "Tunable Parameters"

kmtune - displays the tunable parameters
kmtune -l  <-- This displays a detailed report of the parameters (current, planned, default, minimum, etc)
sam allows you to tune the kernel
Manual Kernel Build (not using sam)  -->  /usr/sbin/mk_kernel -s /stand /build/system

STM

diaglogd

/var/opt/resmon/log

Procedure to use STM to determine memory configuration

• Type stm at the command line
• Type o to select ok
• Press the down arrow in the displayed map and select memory by hitting the space bar
• Press tab to go to menus and arrow over to Tools and hit enter
• Select Information -> and hit enter
• Select Information Log and hit enter
• Information Tool Log for Memory will be displayed
• To print either select Print or SaveAs (to save the log to file for later printing)

System Information

Note:  See section on STM, detailed system information is available with this utility
           Also SAM -->Performance Monitors --> System Properties

OS Information

uname -a - display general information e.g. OS release, node name, machine ID number, etc 

print $(uname -i)16op|dc  hex system id
/opt/itor/bin/i4target -v     spu

file /stand/vmunix   <-- shows whether 64 bit or 32 bit kernel
getconf KERNEL_BITS  <--shows whether 64 bit or 32 bit kernel

Memory Information
dmesg|grep Phy  <-- List amount of physical ram in server
cat syslog|grep Phy <-- List amount of physical ram in server
echo phys_mem_pages/D|adb -k /stand/vmunix /dev/kmem   <-- Lists amount of  4K Memory pages in HPUX 11.x
echo "memory_installed_in_machine/D" | adb -k /stand/vmunix /dev/mem |tail -1 | awk '$2 > 0 { print $2 / 256 }'  <--  Lists memory in MB.
echo "physmem/D" | adb /stand/vmunix /dev/kmem  <-- Lists amount of 4K Memory pages in HPUX 10.x

model   <-- information about the model of the workstation/server

sam --> Performance Monitors --> System Properties  --> Memory Tab

CPU Information

ioscan -fnC processor   <-- shows information about each processor found

echo "itick_per_usec/D" | adb -k /stand/vmunix /dev/mem | tail -1  <-- Shows CPU Speed in MHZ

sam --> Performance Monitors --> System Properties  -->Processor Tab

echo itick_per_tick/D | adb /stand/vmunix /dev/kmem - gives processor speed 

grep model /usr/lib/sched.models - gives type of processor for 10.X systems 

grep model /opt/langtools/lib/sched.models - gives processor type for 11.X systems

Listing all Software

swlist -l product | more

Checking for Specific Software

swlist -l product | grep

Checking for Specific Patches

swlist -l product| grep PH | more

then search for a specific patch (ie PHNE_XXXXX)

Manually applying patches

Patches can be applied using swinstall, just as depots are installed

• swlist -l patch -a patch_state PHKL_25475

swcopy -s /tmp/*.depot -\*@/var/spool/sw

Cleaning up after applying patches:

cleanup
cleanup -c n  <--  commits patches that have been superseded n number of times.  Useful to free up disk space in /var/adm/sw/save.
cleanup -p  <-- previews the actual cleanup tasks but does not actually perform the cleanup

check_patches
show_patches

Creating a single patch depot out of multiple individual depots:

From the directory that has all of the individual depots run this command line script:
for i in PH*.depot
do
        swcopy -x enforce_dependencies=false -s ${PWD}/$i \* @ /tmp/patch_depot         <-- /tmp/patch_depot is the destination directory
done

Remote Access

rcp remote_machine:

remsh

rlogin

.rhosts file needs to be configured or else you will be prompted for username and password (located in home directory)

last -R  - gives address information of last remote login, useful for troubleshooting

Software Installation and Management

To install patches and software use:

swinstall  -->  This will lauch the gui or 
swinstall -x -x -s   -->  This will still lauch the gui, but the parameters will be preselected.  This is use to allow selection of additional parameters that may not be selectable from the gui itself (such as the logging levels below)

For example some popular options are:

• -x mount_all_filesystems=false
• -x logdetail=true
• -x loglevel=2

Note:  

• To install a depot you must specify the complete path to the depot and the depot name.
• To install patches you must specify the complete path to the directory that has the patch files.

Location of  logfiles:
/var/adm/sw/swagent.log
/var/adm/sw/swinstall.log
