dosent look good

Now that I have atleast two blogs, I have scrolled down to check them, Somehow I am not very convinced the way it looks, long and lengthy, I could imagine what would happen after I add another 20 blogs.

May be I am not at the right place. I will do more research to publish my work which can be useful for every unixite.

HPUX: IGNITE

Now on my second Blog, I would like to introduce IGNITE-UX

Setting up a Ignite Box depends on the h/w being used: PA-RISC/Itanium

NOW WE WILL SETUP AN IGNITE SERVER

1.Steps to setup On a Itanium Server

A>On the Server Side

a) Install Ignite-UX-11-ALL_C.7.6.100.depot from

http://docs.hp.com/en/IUX/download.html

#swinstall –s Ignite-UX-11-ALL_C.7.6.100.depot

b) Created the depots on the Server HP UX 11i V3[Both DVD 1 of 2 & 2 of 2]

#/opt/ignite/bin/make_depots -s /dvdrom \-d /var/opt/ignite/depots/Rel_B.11.31/core_media

c) Create the HP-UX OE Configuration Information on the Ignite-UX Server

#/opt/ignite/bin/make_config -s /var/opt/ignite/depots/Rel_B.11.31/core_media \-c /var/opt/ignite/data/Rel_B.11.31/core_media_cfg

d) Add the configuration information to the Ignite-UX /var/opt/ignite/INDEX file.

#/opt/ignite/bin/manage_index -n "HP-UX B.11.31 Default" \-c "B.11.31 From OE Media"

e) I have added the core_media_cfg file is added to the “B.11.23 From OE Media” clause.

#/opt/ignite/bin/manage_index -a \-f /var/opt/ignite/data/Rel_B.11.31/core_media_cfg \-c "B.11.31 From OE Media"

# /opt/ignite/bin/manage_index -x -c "B.11.31 From OE Media"

# /opt/ignite/bin/manage_index -c "B.11.31 From OE Media" -y "B.11.31 0803 OE"

f) Configure the System as an Ignite-UX Server

# /opt/ignite/lbin/setup_server -n

g) Enable the bootpd daemon with the following Procedure:

Procedure

i. Edit the /etc/inetd.conf file:

# vi /etc/inetd.conf

ii. Remove the comment character (#) from the bootpd line:

bootps dgram udp wait root /usr/lbin/bootpd bootpd

iii. Save the /etc/inetd.conf file and exit vi:wq!

iv. Make the inetd daemon reread the /etc/inetd.conf file:

# inetd -c

And after modification it looks as below:-

Entries in /etc/inetd.conf

--------------------------

bootps dgram udp wait root /usr/lbin/bootpd bootpd

#finger stream tcp nowait bin /usr/lbin/fingerd fingerd

shell stream tcp6 nowait root /usr/lbin/remshd remshd

exec stream tcp6 nowait root /usr/lbin/rexecd rexecd

#uucp stream tcp nowait root /usr/sbin/uucpd uucpd

ntalk dgram udp wait root /usr/lbin/ntalkd ntalkd

auth stream tcp6 wait bin /usr/lbin/identd identd

h) To Ignite a Client across the Network, add the Network Entry for the Client to the IP Address File on the Server @ /etc/bootptab.

Entries in /etc/bootptab looks like:-

--------------------------------------

ignite-defaults:\

ht=ethernet:\

hn:\

dn=domain_name.com:\

gw=10.3.90.1:\

sm=255.255.255.0:\

vm=rfc1048:\

bf=/opt/ignite/boot/nbp.efi:

bs=48

iuxclient1:\

tc=ignite-defaults:\

ha=0x00215af8a67c:\

ip=10.3.90.9:

NOTE:

# Example /etc/bootptab: database for bootp server (/usr/lbin/bootpd).

#@(#)B11.23_LR $Revision: 1.4.214.1 $ $Date: 96/10/08 12:46:42 $

# Format:

B>At the client side(Itanium):

Shell>lanboot select –dn

Shell>search

C>Direct Boot Profiles for Itanium-Based Systems at the Clint side

The following dbprofile command, when run from EFI,

Shell>dbprofile -dn testprofile -sip 10.3.90.14 -cip 10.3.90.9 -gip 10.3.90.1 -m 255.255.255.0 -b "/opt/ignite/boot/nbp.efi"

creates a new direct boot profile (or updates the profile if it exists) called testprofile.

The profile contains the following information:

Ignite-UX server IP address (-sip) 10.3.90.14

Ignite client IP address (-cip) 10.3.90.9

Gateway IP address (-gip) 10.3.90.1

Network mask (-m) 255.255.255.0

Boot file name (-b) /opt/ignite/boot/nbp.efi

Shell>lanboot select -dn testprofile

2.Steps to setup On a PA-RISC Server

A>On the Server Side

a) Edit the /etc/opt/ignite/instl_boottab file (don't worry that it appears to be [Read-only]):

# vi /etc/opt/ignite/instl_boottab

b) Add an entry for your client. If a network entry already exists for your client, you may edit it so it looks like the entry below. The client's MAC address should be in hexadecimal, with a leading “0x”.

client_IP_address:client_MAC_address::reserve

c) Save the /etc/opt/ignite/instl_boottab file and exit vi:

:wq!

B>At the client side(Itanium):

Shell>boot lan

HP-UX INTEGRITY VIRTUAL MACHINES(Integrity VM)

Now that I have started my first Technical Blog....

HP Integrity Virtual Machines (Integrity VM) is a virtualization or hypervisor technology within the HP Insight Dynamics – VSE that enables you to create multiple virtual servers or machines with shared resourcing within a single HP Integrity server or nPartition—each with its own 'guest' operating system instance, applications and users. Integrity VM provides automatic, dynamic, resource allocation, based on demand and entitlement.

Online VM Migration

Online VM Migration additionally enables a running VM, its guest OS, and all of its applications to be moved to a different VM Host without any service interruption. Services remain active with no OS reboots or application restarts. All I/O connections to storage and networks remain active during the migration, leaving the change transparent to applications and users.

Using Online VM Migration allows an administrator to do online maintenance (patch, update, or reconfigure) of VM Hosts, as well as balance server (host) loads, without interruption to the VM Host or virtual machines. The functionality can be used in conjunction with other HP tools, such as HP Serviceguard Solutions to provide improved availability and flexibility.

At a Glance

Current version: B.04.20.05
Hardware platforms: Any HP Integrity server (including blades, legacy, Integrity i2 blades and Superdome 2), with or without nPartitions
VM Host Operating Systems: HP-UX 11i v3 (on the new Integrity servers)
Shared resources: processor cores, I/O, tape and DVD changer
Virtualized resources: processor cores, I/O, memory, switch, vLAN
Dynamic: Automatic CPU & memory resource reallocation, memory migration, online VM migration

I have tried out 4.1 and hence I give the description for HPVM 4.1, however there is no much difference in the creation of the Host/Guest.

Download HPVM 4.1 from the below website:

https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=integrity_vm41

NOTE: The above is only a trial version. You will have to buy the full version. Also just fyi.. HPVM 4.2.5 is the latest version.

Having said that HPVM 4.1 is supported only on HPUX 11.31 and onwards.

Install the below patches from http://www.itrc.hp.com

PHSS_37312 (Integrity VM)

PHSS_37306 (VMagent)

Install the Integrity VM Media Kit

I am creating lvols cos I do not have any left on my Box.

# lvcreate -L 40960m -n lvol9 vg00

# lvcreate -L 40960m -n lvol10 vg00

# lvcreate -L 40960m -n lvol11 vg00

# lvcreate -L 40960m -n lvol12 vg00

Now I will create a VM Guest:

# hpvmcreate -P VM03A -O HPUX:11.31 -c2 -r1G

# hpvmmodify -P VM03A -a disk:scsi::lv:/dev/vg00/rlvol9

# hpvmmodify -P VM03A -a network:lan::vswitch:vswth01

# hpvmstart -P VM03A

Assigning a Virtual dvd

hpvmmodify -P VM03A -a dvd:scsi::disk:/dev/rdsk/c1t0d0

hpvmmodify -P VM03B -a dvd:scsi::disk:/dev/rdsk/c1t0d0

hpvmmodify -P VM04A -a dvd:scsi::disk:/dev/rdsk/c1t0d0

hpvmmodify -P VM04B -a dvd:scsi::disk:/dev/rdsk/c1t0d0

I have now managed to create four Virtual Guests viz., VM03A,VM03B,VM04A,VM04B

Assign the LVOLS:

# hpvmmodify -P VM04A -a disk:scsi::lv:/dev/vg00/rlvol9

# hpvmmodify -P VM04B -a disk:scsi::lv:/dev/vg00/rlvol10

Now each VM has a disk.

Next is LAN.

Create a virtual switch on a physical NIC (here lan0), name it vswitch01:

# hpvmnet -c -S vswth01 -n 0

power on the vswitch:

# hpvmnet -b -S vswth01

assign the network:

# hpvmmodify -P VM04A -a network:lan::vswitch:vswth01

# hpvmmodify -P VM04B -a network:lan::vswitch:vswth01

start the VMs:

# hpvmstart -P VM04A

# hpvmstart -P VM04B

Connect to the vMP of the first VM:

# hpvmconsole -P VM04A

and proceed to install HP-UX via IGNITE-UX.

NOTE: You can install OS on the Guest using Disk/ISO/IGNITE.I have chosen IGNITE.

In my second blog we can discuss on IGNITE-UX.

Introduction

Well, i was going through the 1000's of Blogs related to the Environment UNIX, and something struck my head and thought to create one more to add to the 1000's.

However I wanted this one to be useful to everyone right from learners,Jr. Sys. Admins to Sr. Sys. Admins.

I would like to include anything & everything which hits my head with the limitation to the Unix Environment(HP-UX; Solaris; AIX; Linux; MAC OS) including Operating System, Hardware, Storage connected to it and if possible Networking though my knowledge on this is limited.

Any kind of comments to improve this blog or ideas to create a new one would be helpful.

Happy Blogging!!
