How to find the console IP address in HP-UX Servers

In this post, I will guide you to how to find the console IP address in HP-UX operating system if we lost or forgotten. So here, I will provide you the simple steps to get back the console IP address of HP-UX system.

For Itanium systems running 11.31 version only we can use smh and the cprop command. These both method works to recover the forgotten password.

cprop is what the smh webpage uses to retrieve the IP address. Run the smh webpage (hostname:hpx)

Home -> System -> Management Processor

It is show you the IP address of console port. Also please find the below "cprop" command usage, how to we run this command.


hpx:/>/opt/propplus/bin/cprop -summary -c “Management Processor”

[Component]: Management Processor
[Table]: Management Processor
——————————————————-
****************************************************
                   [Hash ID]: Management Processor:11a64d1ax41eed6da
                    [Status]: OK
                 [IPAddress]: 192.168.1.23
                       [URL]: https://192.168.1.23
                     [State]: Enabled
****************************************************

For PARISC boxes and Itanium models running 11.23 or earlier, you must use the serial port on the back of the box. The commands will be:

ctrl-a (to get the attention of the console interface)
<login> typically Admin and Admin
CM (to get to the command menu)
LC
MA (to exit the CM menu)
X  (to exit the GSP or MP menu)

You need to connect a serial cable on Serial port of the HP-UX server and connected to own laptop. Once you will get the ssh or telnet session from serial connection, you need to run the above command to get the IP address of HP-UX console.

Sometimes the serial port is not working then in this case you need to login in serial management port of the server and recover the IP address again.

How to Create VNIC and Assign a IP Address on Solaris 11

Hello Friends,

In my old post, I described that how we will create a new local solaris zone on global zone. As you know every zone has their own networking but how it is works and configured we need to understand, So in this post, I will explain to you how to create a virtual network on Solaris 11 before zone creation.

For creating Virtual NIC and assigning fix static IP address in Solaris 11 we need to understand the basic difference between older version of Solaris and Solaris 11.

In Solaris 10, according to the NIC manufacturer,physical network interfaces are named as (Ex:bge,e1000g,nxge).But in Solaris 11 onwards,the names are hidden from the view and all the interfaces will be named as net0,net1…netx.

Before forward to main work we need to know that using which command we can check which interface has been mapped to physical interface. Using below command you can check all the network interface details.

sun01# dladm show-phys

LINK              MEDIA                STATE      SPEED  DUPLEX    DEVICE

net0              Ethernet             up         1000   full      bge001

net1              Ethernet             up         1000   full      bge002

If you want to show all dladm level devices,including VNIC’s & aggregation links,use the below command-

sun01# dladm show-link

LINK                CLASS     MTU    STATE    OVER

net0                phys      1500   up       --

net1                phys      1500   up       --

In Solaris 11,you can give a meaning full description(net1/oracle_VIP) to all the IP address on the system unlike Solaris 10. (e1000g1:2)

How to assigning new IP address to NIC:-

1. We can see how we assigned IP address to the physical interface, so in the first step we will check all the physical interface using below command.

sun01# dladm show-phys

LINK              MEDIA                STATE      SPEED  DUPLEX    DEVICE

net0              Ethernet             up         1000   full      bge001

net1              Ethernet             up         1000   full      bge002

2. In this step we would know how we will create a new interface so you can use the below command for this.

sun01# ipadm create-ip net1

3. This is the main step to assign the static ip address to the newly created interface net1. You can use below command or syntax to assign the fixed IP.

sun01#ipadm create-addr -T static -a local=10.135.0.2/24 net1

You can change your IP address accordingly. 

4. Now we will Verify whether IP address is configured or not which we assigned on above step.

sun01# ifconfig  net1

net1: flags=1000843 mtu 1500 index 7

        inet 10.135.0.2 netmask ffffff00 broadcast 10.135.0.255

        ether 0a:cB:12:8e:15:e2

If you see the above output, the new IP address is shown on net1 interface successfully. Using above all 4 steps you can know how we will assinged the static ip address to the sun solaris 11 operating system.

Now we will go for Virtual Network Interface creation steps.I can create N number of VNIC’s using single physical interface.These VNIC are treated as actual physical interface and possible to assign to local zones with  full access to it.

How to create a new VNIC using interface net2:-

1. In the initial steps I will run the same command to check out the all physical interface which is available on the Solaris 11 Server.

sun01# dladm show-phys

LINK              MEDIA                STATE      SPEED  DUPLEX    DEVICE

net0              Ethernet             up         1000   full      bge001

net1              Ethernet             up         1000   full      bge002

net2              Ethernet             unknown    1000   full      bge003

If you see the above command output network interface "net2" is in unknow state, So in the next step I will create a new VNIC using net2.

2. In this step we will create a new VNIC using net2. In my case i will suppose VNIC name “vnic01”, so for creating the new VNIC we will run the below command which describe below.

sun01#dladm create-vnic  -l net2 vnic01

3.Now, We will plumb the virtual interface and create a default IP to new VNIC.

sun01# dladm create-vnic  -l net2 vnic01

sun01# ipadm create-ip vnic01

sun01# ifconfig vnic01

vnic01: flags=1000842 mtu 1500 index 8

        inet 0.0.0.0 netmask 0

        ether 2c:18:10:Ce:1a:12

4. Now we will assign the new IP address to VNIC and verfif that new IP for vnic01 is configured or not.

sun01# ipadm create-addr -T static -a local=10.135.0.3/24 vnic01

sun01# ifconfig vnic01

vnic01: flags=1000843 mtu 1500 index 8

        inet 10.135.0.3 netmask ffffff00 broadcast 10.135.0.255

        ether 2c:18:10:Ce:1a:12

5. In the final step we will try to run snoop on VNIC which we have create now. You can verify through snooping is that VNIC01 is working fine or not.

sun01# snoop -d vnic01

The same way you can create a multiple VNIC and assign a new IP address to it. Hope you got some idea about Solaris 11 networking part after reading this post. Please let me know if you have any doubt regarding this post.

Step by step method to configure static IP address in Solaris10

Please find the step by step method to provide the static ip address on Solaris 10 operating system.

Step 1: Please run the below command to delete the old ip address. In my machine the "net1" Ethernet card is configured already.

sun> ipadm delete-ip net1

Step 2: To check the current status of all Ethernet card attached with machine as per below command.

sun> ipadm show-if -o all
IFNAME     CLASS    STATE    ACTIVE CURRENT       PERSISTENT OVER
lo0        loopback ok       yes    -m46-v------  46--       --
net0       ip       ok       yes    bm46--------  46--       --
sppp0      ip       ok       yes    -m4-p-------  ----       --

Step 3: Please create your new Ethernet card as per below command.

sun> ipadm create-ip net1

sun> ipadm show-if -o all
IFNAME     CLASS    STATE    ACTIVE CURRENT       PERSISTENT OVER
lo0        loopback ok       yes    -m46-v------  46--       --
net0       ip       ok       yes    bm46--------  46--       --
net1       ip       down     no     bm46--------  46--       --
sppp0      ip       ok       yes    -m4-p-------  ----       --

Step 4: To provide the static IP address please run the below command. Please change your IP address with highlighted address.

sun> ipadm create-addr -T static -a 172.26.7.29/16 net1/v4
