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.
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   --> 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

7400 Disk Array

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
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
  • volume group name  --> mapfile name
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/

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

CIFS (Samba)
/opt/etc/samba/smb.conf
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  <-- 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

Bootup/Shutdown
shutdown -r 0 --> reboot
shutdown -h now  --> shutdown and halt
shutdown 0 --> shutdown to single user mode
reboot 0 --> reboot
init 1 - single user mode
hpux -is  boots single user mode

Interupting the boot process:
  • Configuration Menu
  • Information Menu
  • Service Menu
GSP Mode
  • From the console hit
  • Hit at the GSP console login (default is no password)
  • Now low level commands can be entered
    • ps  --> power status


To reboot to single user mode:
  1. shutdown -r 0
  2. hit during 10 sec window to interrupt reboot
  3. enter:
  4. interact with ipl? yes
  5. hpux -is  (i=init, s=single user)


To reboot manually to init 3 level
  1. shutdown -r 0
  2. during 10 sec window
  3. bo
  4. interact with ipl  --> yes
  5. hpux -is   (i=init, s=single user mode)
  6. mount -a
  7. init 3
Startup/Shutdown Scripts

/sbin/init.d
/sbin/rc0.d                                These are all linked to actual scripts in /sbin/init.d
