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)

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

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

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

Migrating the printer configuration from one server to another server using SAM:

On the source server:

• SAM  --> Printers & Plotters --> LP Spooler --> Save/Restore Spooler Configuration
• Actions --> Save Spooler Configuration
• This saves the information in the directory /var/sam/lp
• Save this directory using tar:  "tar -cvf /tmp/lp.tar /var/sam/lp"
• Copy this tar file to the destination server

On the destination server:

• Extract this file:  "tar -xvf lp.tar"
• SAM --> Printers & Plotters --> LP Spooler --> Save/Restor Spooler Configuration
• Actions --> Restore Spooler Configuration

Login Environment

/etc/profile - main profile for all users

/etc/profile.env

export TMPDIR=/tmpsort
export TEMPDIR=/tmpsort

source a profile:    ". ./profile"

Changing prompt:

export PS1=$(hostname):'$PWD # '

This gives a prompt that has the hostname followed by the current directory, ending in the # (useful for root logins).

Networking

netstat -a   <--ports
netstat -i  <--interfaces
netstat -r  <--routing table
netstat -rv  <--routing table and subnet mask

lanscan - provides hardware information about the nics in the server
lanadmin - menu driven interface to administer lan nics
lanadmin -x 0  bypass menu and show lan driver specific options for nic with id 0
lanadmin -X 100FD 0  - bypass menu and set nic at id 0 to 100 MBS, Full Duplex

ioscan -fnkC lan   - shows ioscan information for device type "lan"

lanscan -i|awk '{print $1}'|xargs -i ifconfig {}   -> does an ifconfig on all defined interfaces on that server

Changing the IP Address and Subnet mask:

• set_parms ip_address
• Then supply ip address and subnet mask when prompted.  This process will require a reboot.

ntpq -p   --> lists time sync status with that server (slightly different detail than ntpq -p)

/etc/ntp.conf  --> configuration file
Changes to the configuration require ntp daemon (xntpd) be stopped and restarted (restart is not recognized):

• /sbin/init.d/xntpd stop
• /sbin/init.d/xntpd start
