Device Management

HP-UX is a hardware path based operating system.  When it boots up it does a hardware detection.  It then compares the hardware that it detects with the hardware that is listed in /etc/ioconfig.  If new hardware is detected, it is assigned the next available configuration information in the proper hardware path.

rmsf - remove special files

insf - install special files

insf -C disk -e   ←- This command will re-install all of the device files for the class “disk”

lsdev   ←- Lists devices and drivers in the system

ioscan   ←- searches for all devices and displays their hardware path

ioscan -fnC disk  ←- searches for all devices of  class (C) disk

ioscan -fnH <LUN>  ←- searches for a LUN

last 2 digits of hardware path in the LUN in octal  (1/12/0/0.1.23)

Disk Devices

A disk device will have a name in the following format:  c#t#d#

  • c# is the card number
  • t# is the target number
  • d# is the LUN - this is normally 0 unless RAID is being utilized

scsictl -a /dev/rdsk/c?t?d?  ←- display control parameter information about the disk device

scsictl -a -m queue_depth=4 -m queue_depth /dev/rdsk/c?t?d?      ←- sets the queue depth

CD-ROM Devices

nohup /usr/sbin/pfs_mountd &  - starts process

nohup /usr/sbin/pfds &  - starts process

pfs_mount -o xlat=unix /dev/dsk/c0t1d0 /cdrom        - mounts cdrom

Cdrom won't eject:

  1. pfs_umount -c OR
  2. kill -9 pfs_mountd and kill -9 mountd

Cdrom won't mount using:  pfs_mount -o xlat=unix /dev/dsk/c0t1d0 /cdrom

  1. nohup /usr/sbin/pfs_mountd &
  2. nohup /usr/sbin/pfsd
  3. /usr/sbin/pfs_mount /cdrom    ←- this uses mounting information in /etc/pfs_fstab

  • armdsp -a va7400   ←- real time display of the disk array
  • armmgr -D va7400 HPA6189A00SG218H0024
  • armdiscover  /opt/sanmgr/commandview/client/sbin    –>  Tells us the serial number
  • armhost -d <Array Worldwide Name> <Serial #>
  • armhost -d 50060b000014e313 00SG218J0024
  • ioscan -fnc disk | more

cvui - creates luns

  • Choose storage array
  • Create LUN
    • Find last LUN
    • Create with new lun number
  • View existing luns

Process to export disk configuration to a file:

  • sam –> actions–>export

Fibre Channel Devices

ioscan -fknC fc  ←- Lists fibre channel adapters.

To identify the devices:

ls -l /dev/fc*

fcmsutil - utility for fibre channel operations

fcmsutil /dev/<device>

Procedure to run fcmsutil on a fibre channel:

ioscan -fnC disk|more   –> Identify hw path of fibre channel adapter

ioscan -fnH 1/0/0/0  –>  Identify device of fibre channel adapter

or ls /dev/fc* on older adapters (arbitrated loop)

fcmsutil /dev/fcms2 stat  –>  fcmsutil that shows status of fibre channel adapter

Login Environment

/etc/profile - main profile for all users


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).


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.

Changing the Default Gateway

  • cd rc.config.d
  • vi netconf

Network Time Protocol (NTP)

ntpq -p   –> lists ntp peers and their time sync status

ntpq -p <server fqdn or ip address>  –> 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


Command Description
cancel deletes print jobs from queue
hppi jet admin
ls -d<destination> -o<optioni> file prints a file
lpsched -v
lpstat lists jobs in queue. -s  -t
pr .profile lp -n3 prints

/etc/lp/interface - interface scripts


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

Process Management

Command Description

inetd -l starts logging in /var/adm/syslog/syslog.log
ps -ef grep PROD list all processes, but only show those processes that have “PROD” in them
/sbin/init.d/<script> [startstop]If the script exists, this will stop and start the associated processes.  

/etc/services   –>  Lists the services and their configuration

/etc/inetd.conf  –> Lists the services and their configuration

/var/adm/inetd.sec   –>  This file contains security information on who may request a particular process

Remote Access

rcp <source> remote_machine:<path>

remsh <host>

rlogin <host>

.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 <option> -x <option> -s <path to depot>  –>  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)

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


  • 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:



Listing all Software

swlist -l product | more

Checking for Specific Software

swlist -l product | grep <SEARCH STRING>

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 -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



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


        swcopy -x enforce_dependencies=false -s ${PWD}/$i \* @ /tmp/patch_depot         ←- /tmp/patch_depot is the destination directory

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 

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

kmtune -l  ←- This displays a detailed report of the parameters (current, planned, default, minimum, etc)

sam allows you to tune the kernel
