change Service Processor from one 3Par 7200c to another 3Par 7200c

[Blago]

Hey, boys and girls,

I have the following issue: production 3Par 7200c StoreSrv that is already in production, no SP or VSP connected to it. I have no idea what the ip address configured to this storage is.

I have another test 3Par 7200c StoreSrv connected to a physical SP.

Is it possible to somehow connect the physical SP from the test 3Par to the production 3Par?

I am aware that one StoreSrv could be connected to one SP.

Cheers

Hi Blago,

Yes. You can connect the physical SP from the test 3PAR to production 3PAR.

You need to freshly configure that with the production 3PAR.

You can get the IP of Production 3PAR with the cli command 'shownet'.

You don't know the IP of the production SP?

Connect a monitor or connect via the service LAN, log on and you will see it.

However, if you want to swap the SP you need to re-image the SP, at least for version 4.4.

10x for the reply and info, Srinivas!

Well that is the thing we have no idea what the IP of the production 3PAR StoreSRV is.

Tried to connect with the console cable but no luck so far since there is no official documentation for it. It seems the serial connection to the StoreSRV is just for HP engineers.

What hardware model is your SP?

[Blago]

Hello, Torsten,

I do know the IP of the SP( HP DL120 ) that is connected to the test 3PAR 7200c StoreSRV.

I have connection to it and removed the test StoreSRV and tried to add the production 3PAR 7200C StoreSRV, both form console and web, without success. It seems that the SP keeps the Serial number of the test StoreSRV in both web and cli and I am unable to add new SN until re-image.

I will follow your advise and re-image the SP, because a swap is probably the only way to find the production storage IP. The version I have on the SP is 4.4.0.GA-88. As per documentation when I put re-imaged SP in the same broadcast domain as the production 3PAR 7200c StoreSRV. I would be able to enter new SN then and hopefully the production StoreSRV. I hope I will be able to set a network address to the production StoreSRV.

Currently I am scanning the 192.168.0.0/16, 172.16.0.0/12 and after that 10.0.0.0/8 . I will do the re-image of the SP as a last resort option.

I wonder if I am going to loose any data or configurations once I connect the SP to the production StoreSRV?

Also, I wonder if I am going to loose, if any, licenses on the SP if I re-image it?

Once again thanks for the info!

Please wait ...

So you have a DL120 and you don't know the IP of it.

At the back you have 2 ethernet ports - left labeled mgmt, right labeled service.

The service port has the same funcionality as management, but a fixed IP address.

The SP service port has 10.255.155.54, mask 255.255.255.248.

Set your PC to 10.255.155.49, mask 255.255.255.248, connect it directly and point a putty session to 10.255.155.54.

Log on using your known cretentials.

Now you will see the IP address of the public port.

Hi, Torsten,

if I am not confused SP stands for Service Processor, which is a server, connected to a 3PAR Storage.

I have access to the IP of the SP and it's web interface and cli over ssh.

The IP address I do not know is for my production 3PAR Storage. As per documentation each and every 3PAR storage have different default IP address that is generated by it's SN. Once a SP is connected to the 3PAR Storage, it checks the SN and then connects the IP of that server providing further configuration options for changing the 3PAR storage IP address.

Please, correct me if my understanding is wrong.

Cheers

So you can logon to this SP?
The 3PAR is connected to this SP?

So it will show you the IP of the 3PAR there.


EDIT:

I read everything again and understand now there is no SP on this 3PAR at all.

So you need a serial connection to the 3PAR, log on and get the details.

There is no default IP, at least after initialization of the hardware.

You can also run a CLI session from there to the 3PAR and run shownet.

Hye, Torsten,

oh I got it, once intiliazide(probably from a serial connection) the production StorSRV has no IP and my only option is to connect via serial.

I will leave the IP scan finish any way since there is some chance my former colleagues to have configured one.

Cheers

[Torsten. · Accepted solution]

I'm sure the 3PAR has an IP, but maybe someone has set it to something really odd.

However, each 3PAR comes with 2 LAN cables (red and blue) and 2 adapters (grey and black).

Take a normal LAN cable (e.g. the blue) and connect it to the MFG port of the 3PAR node 0.

Then connect the grey adapter 180-0055 to it. Connect this to a PC, use terminal emulation (putty -> serial), set speed to 57600 and connect.

Now you can logon using your 3paradm user and password (default was 3pardata), then run "shownet" to get the IP.

Thanks, Torsten!

I found the IP connected and well it turned out I have a Node 1 Failed (Node Offline Due to Failure {0xd})

I guess I have to open another post for the replacement procedure and should I go for it at all.

Once again thanks a mil!

[Torsten.]

OK.

But you need to have a SP connected to this 3PAR.

It can inform you (by mail) about hardware failures and in case you have a support contract it can call home and open a support case automatically.

Nevertheless it is needed in case of patching and firmware updating he hardware.
