How to change HPUX HBA, date, timezone

by mn.sobieh

As a continuation of the HPUX for Linux Admins series. This article explains how to display the HPUX system settings then explain how to edit them. for example, the display HBA configurations like WWN or change server Date, time, and timezone.

You should be able to use the keyboard to navigate the terminal and know the basic commands and their syntax from previous articles.

Contents

  • Gather System Information.
  • Change System settings.
  • Check Fiber Card WWN.
  • Change Date, Time, and Timezone.

We will go through UNIX CLI and show common HPUX commands for monitoring and network control commands

CommandDescription
uname –rTo view OS Version of your HPUX  
glance  To find the server’s memory size and other details: (external tool) In the output you will find physical memory size in the output.
ioscan -C processorTo list the processor information:
uname –mTo display the system architecture:
model getconf MACHINE_MODELTo display machine model:
swlist HPUX*OE*  To display Operating Environment and OS Version. In addition to the latest OS update.
getconf HW_CPU_SUPP_BITS  To show Hardware(CPU) bit:
getconf KERNEL_BITS  To show Kernel bit:

To get the Server serial number: (Use any of the below):

echo "sc product system;info;wait;il" | cstm | grep -i "system serial"
echo "sel path system\ninfolog\nexit"|cstm|grep "System Serial"
getconf MACHINE_SERIAL 
machinfo | grep "machine serial"

Display HPUX HBA information

Assuming that you have an HBA (Fiber Channel) Card installed on your server. and you need the WWNof this card.

First, Issue the command to show HBA settings.

ioscan -nfC FC

It will show you the device path for the desired FC. for example, /dev/fcd0

Nex, Issue the following command to display the device full configurations including the WWN

fcmsutil /dev/fcd0

Look for a line with the words

N_Port Port WWN which will contain your fiber card identifier.

Modify Settings:

To set the hostname, IP address, date/time, DNS/NIS server details, default gateway after the OS installation:

This command will run automatically after the OS installation.

 set_parms initial

Change HPUX Date, time, Timezone

It is essential to make sure that the server has the correct time, as it could cause many issues. for example, SSL related issues, Server out of sync is it was working in a cluster, or at least

specially if the sever com To change the date and time:

 set_parms date_time

To change the timezone:

 set_parms timezone

Wrap up

Yet, few commands allow Linux Admins to dive deeper into HPUX settings. Thus, they can complete their tasks. In this article, we were able to Display HBA details (WWN) and change Operating system Date, time, and timezone

How to fix mount DVD error in HPUX

by mn.sobieh

If you are getting an unrecognized file system error message when you mount DVD on the HPUX server. This article gives multile methos to fix the issue and achieve you objective.

Now, we will have a real-life scenario where an Oracle DBA is trying to install Oracle 12c on an HP Integrity Servers with an Itanium processor. hence, These servers are using HPUX as their Operating System.

How to manage devices in HPUX

by mn.sobieh

After knowing how to navigate the HPUX terminal In this article, we will explain how HPUX hardware detection works and tools used to manage HPUX devices. For example how to show device details and configure it.

HPUX harware detection

similarly, HPUX uses files located in /dev/ directory to access the hardware and its devices. Most of the devices and their device files are configured automatically during the boot time.

On boot time, HP Unix try to connect all devices and executes /sbin/ioinit.rc script will create new device files if needed. 

HPYX Device Management commands

The following HPUX commands will be useful in case that you needed to manage a disk or check the network or device information. For example, To show all the configured devices:

# ioscan -f

list the available disk/CD Drives along with their device file details: 

# ioscan -funC disk

To list the tape drives :

# ioscan -funC tape

As before, ioscan command is a powerful tool that allows you to manage various HPUX devices. As another example for it It can list all LAN adapters by defining the following argumant:

# ioscan -funC lan

To show the details of a device file:

# lssf /dev/rmt/0mn

configured the recently connected tape drive:

# insf -C tape

To configure newly connected CD Rom or disk

# insf -C disk

Wrap up

This article shows some commands that will help you Linux Administrator in network and device management of HPUX systems. for more details you could visit this blog.

HPUX Terminal navigation Keys

by mn.sobieh

HPUX system might appear challenging at first glance, however, after reading this article you will find it more familiar than you think. This article will show how to use keys to navigate into the HPUX terminal and commands similar to what you know in Linux.


“Linux is a UNIX like Operating system” 


The trick is to know how to begin and respect ^_^ the differences between both Operating Systems. As for a Linux Administrator who comes from a friendly environment GUI (like KDE or Gnome) with backgrounds, sound, and even some games ^_^ . Not to mention, a CLI -bash- that has auto-complete for commands, file paths even command parameters. Some Linux distributions even have auto-suggestion if you misspelled command

Now, this dude will work in a strange environment in which the arrow keys refuse to do what they normally do :O

After a lot of suffering, You will find that it’s really similar to Linux more than you expect 😀

Contents

  • Navigation Keys in HPUX shell.
  • Typing and editing commands. 
  • HPUX commands Similar to Linux.

Navigation Keys in HPUX shell

Working with Shell in HPUX is similar to working in the VI editor. It has two modes  Command mode &
Insert mode. We press ESC and [Keys] to switch between modes

  • Navigation Keys (command mode).

are the old keys ( H , J , K , L )
H=Left

J=Down

K=up

L=right

KeyFunctionality
hMove the cursor to the left one character.
lMove the cursor to the right one character.
jMove the cursor down one line.
kMove the cursor up one line. (Show the last command)
^Move the cursor to the beginning of the line.
$Move the cursor to the end of the current line.

Typing and editing commands.

Similarly, as the navigation keys mentioned above. applying the following sequence of keys inside VIM or in HPUX Terminal will facilitate your operation.

Press ESC then press one of the following [Keys] will execute the described functionality.

KeyFunctionality
iInserts text to the left of the cursor. (enable you to type and execute commands)
aBegins inserting after the character (append) on which the cursor is positioned.
rReplace the character under the cursor with the next character you type.
xDelete character(s) to the right of the cursor, starting with the one beneath it.
XDelete character(s) to the left of the cursor, starting with the one beneath it.

HPUX commands Similar to Linux.   

The following list will show commands similar to Linux. however, you might find it lacking some parameters you use.

File manipulationls, rm, cd, mkdir
Text stream and editingcat, tail, head, vi
Permissionschown, chmod
Process, memoryUptime, ps, top, top

Wrap Up

This introduction is necessary to make the Linux administrator familiar with the HPUX commands and environment especially using navigation keys. Next, we will explain more in-depth objectives. for example software, device management, system info, and other commands.
