Background: To reward Mr. W's contribution to the successful delivery of the "shopping carnival" on Singles' Day (which falls on Nov. 11), his boss decides to give him a free vocation to Maldives (I wish I could work for this kind of boss, LOL). After this romantic holiday, Mr. W suddenly finds that the alarm indicator of a storage device is blinking red while recalling his marvelous vocation. When opening the maintenance terminal and logging in to the ISM, Mr. W realizes that he forgets the IP address of the device management network port. If he cannot clear the alarm, he will definitely let his beloved boss down and his "golden" job will be no more. How stupid he is! What is he supposed to do?

Luckily for him, we have Storage Journal: Tips for Modifying the IP Addresses of Management Network Ports and Its Impact. Check it out!

 

[Retrieving the IP address of a management network port]

1.Connect the maintenance terminal to a storage device using a serial cable.

2.Use the super terminal to log in to the serial port. (For details, see the appendix.)

3.Run showctrlip to retrieve the IP address of the management network port.

[Modifying the IP address of a management network port and its impact]

1.Connect the maintenance terminal to a storage device using a serial cable.

2.Use the super terminal to log in to the serial port. (For details, see the appendix.)

3.Run chgctrlip to modify the IP address of the management network port.

Let's use how to modify the IPv4 address as an example. Modify the IPv4 address, subnet mask, IPv4 gateway of controller A's management network port to 129.16.40.111, 255.255.0.0, and 129.16.0.1 respectively.

           

Let's use how to modify the IPv6 address as an example. Modify the IPv6 address, prefix length, and the IPv6 gateway of controller A's management network port to 2900::111, 64, and 2900::1 respectively.

           

Precautions:

1. When the IP address of the management port is modified, services are not affected, but the ISM might disconnect from the storage system. Do not modify the IP address of the management network port unless necessary.

2. The IP addresses of the management network port and the iSCSI host port must be on the different network segments. Otherwise, route conflicts occur.

[Changing a password]

1. If a read-only user or administrator forgets its password, perform the following steps:

    a) Log in to the CLI as user admin.

    b) Run resetuserpwd to initialize the password.

    c)  The initial password is Admin@storage.

2. If you forget the password of user admin, contact Huawei technical support hotline.

After reading the T Series Storage System Maintenance Guide, 99% of audiences have a clearer idea about how to modify the IP addresses of management network ports and its impact.

With the help of O-man, Mr. W finally retrieves the IP address of the management network port and rectifies the fault. However, his challenges are way far from over. What is waiting for him? Can he achieve the dreams he ever dreams of? Will he live happily ever after? Who knows? Let's wait and see.

We will keep you updated in the next-issue Storage Journal. To be continued....
