Welcome to this second tutorial about technological solutions “Huawei SAN Storage”.
Assigning the management IP Addresses
The topic of the day is “Assigning the Management IP Addresses”, in order to access, configure and diagnose the SAN Storage device, using the ISM (Integrated Storage Management) software.
As for the previous tutorial, we will use as a demo the smallest unit of the Oceanstor product line: S2200T.
The S2200T is the smallest one as hardware solution, but it has standard SAN capabilities and, more important, it uses the same management console as the bigger ones: the ISM (integrated Storage Management)

To begin with this task, we have to start working with an old IT technology: RS-232 serial communication.
At first, we have to use the serial cable supplied with storage.
In support of the serial cable, either we have to use a PC with an old RS- 232 port, or an actual laptop equipped with a converter like the one pictured here: USB to RS-232.

After having joined the converter to the serial cable, use the other end of the latter to plug the RJ-45 connector to the SAN, in the port bearing the following symbol: |O|O|. (that is positioned towards the middle of the rear panel, like in the following picture).
There are two ports of this kind (CONSOLE), one for each controller: you can use either one or the other indifferently, since you can use one to configure the other, as you like.

Now let's turn to the activities to be performed on the PC.
We will use the freeware PUTTY as terminal emulator.
Training on PUTTY is not our purpose, however I will list the necessary settings required by the SAN, so you can use them on your preferred terminal emulator.
Briefly, we have an 8n1 at 115200 bps without flow control.
In detail, on the serial settings screen (last leaf of the tree on the left), we have to type:
- COM 4 or equivalent: it is assigned by the computer to the USB-RS232 converter. It varies from PC to PC.
- SPEED: 115200
- Data Bits: 8
- Parity: none
- Stop Bits: 1
- Flow Control: none (as default PUTTY offers xon-xoff)

Click Open to return to the main screen, where you click to Serial (see picture here, near the mouse pointer) then click again OPEN.
Now it should open a black screen, and, if everything is well connected, after pressing enter 2 times, it will ask us to login

The default credentials are: user=admin, password=Admin@storage
If everything is typed correctly, the storage will reply with the welcome screen in the picture here on the right.
Now we are ready to enter the management IP addresses !

The command that we will use is chgctrlip (ie: Change Controller IP)
We can see here an example of the default syntax by typing :
help -c chgctrlip
The highlighted line is our example, so we just have to customize the IP parameters to match our environment, and remember to set the appropriate address on each controllers: a and b.
The controller is simply identified by the character between -c and -ip.
Here's how it answers to the actual command.

At this point, let's verify that the address have been acquired correctly and leave.
Our command is showctrlip.
Finally, if we can ping the SAN from our computer or our server, we can say we did everything correctly.
As a double check, we can try and access via HTTP, and here is what we get: the installation prompt of the ISM.
