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--  commits patches that have been superseded n number of times.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

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.
