Welcome to the EM CE services.
How to session for EC support solution article E MC 279637. How to change IP addresses for a VX unified storage system running OE for file 7.0 0.35. And later this video demonstrates how to change the IP addresses for the control station and storage processors in a VX unified storage system including the different procedures for moving the VX to a new subnet and within the same subnet, this video applies only to VX unified systems running VX OE for file 7.0 0.35 and later operating environments.
This video demonstrates the task you must complete when you want to change the IP address used by a VX unified storage system to a new IP address on a new subnet or to a new IP address within the same subnet. To do this task. You will need the current IP address information including the network gateway IP and Subnet mask for the control station and SP A and S PB storage processors as well as administrator login credentials for the control station command line and unisphere interface.
You will also need three available IP addresses on the new subnet or within the same subnet. These should be provided by your land administrator. You will need an RS 2 32 DB nine female to female null modem serial cable to make the physical connection from the control station maintenance port to a windows host the E MC part number for this cable is listed here, but you can use any standard DB nine null modem female to female cable.
However, you need to make sure your cable is a null modem serial cable and not a straight through serial cable. Also many new Windows P CS do not have a DB nine male connection port anymore. If your Windows system does not have a DB nine male connection port, you will need a USB to RS 2 32 DB nine male cable adapter to connect the female DB nine cable and probably software drivers for that adapter. Finally, if you are moving the V next to a new subnet, you will need an available physical land port connection and cable.
Your local network administrator should also be able to provide you with this. The tasks you will need to do are different depending on whether you are changing the VX system IP address for a move to a new Subnet or to use a new IP address within the same subnet. This video presents these two procedures in two separate demonstrations. Now let's look at what you need to do to change the IP addresses for a VNX unified array that is being moved to a new sub net to change the IP addresses for a VNX unified array that is being moved to a new subnet.
You will need to do the following connect the vex maintenance port on the primary control station CS zero using an RS 2 32 DB nine connection from a windows host then connect to the control station command line using a serial terminal emulator program like Putty. Next stop the proxy ARP surface for the SP I and S PB VNX storage processors. This will reset the VNX SPS to the default IP addresses, then change the CS zero IP address and verify the change.
Next, move the CS zero land connection to the new V land of changing to a new subnet for dual control station VX systems. You will then need to change the IP address of the CS one. This task is not demonstrated in this video, but the steps are described at the appropriate point in the demonstration. Then start the proxy ARP service and specify the new IP addresses for the SP A and S PB V NX storage processors.
Finally connect and log in into unisphere at the new IP address and verify that you are able to manage the VNX at the new IP addresses to make the physical connection to the VNX maintenance port. You will need a DB nine RS 2 32 null modem cable with female to female connectors like the one shown here. Also, since most P CS do not have a male DB nine connector, but do have one or more USB ports. You will probably need a USB to DB nine male serial cable adapter. Like the one shown here.
If you use this kind of cable adapter, you will also need to configure the driver with the same serial communication settings required for connecting to the VNX control station command line management interface. As described later in this video in a dual control station, VNX, the CS zero control station will be the unit on the bottom. As shown here, the CS zero management port is a DB nine male serial port on the far right to make the physical serial connection to the VNX.
Connect the female connector on one end of the DB nine RS 2 32 null modem cable to the DB nine male serial port for the CS zero management port. Connect the other end of the cable to your PC. If you're using a USB to DB nine serial cable adapter, connect the adapter to the no cable as shown here. If you're using an adapter like this, you will also need to configure the driver for the adapter. Now it's time to connect to the VNX control station command line interface launch putty or another serial terminal emulator program configure the serial connection settings for the program.
As shown here. You may need to change the com port for your connection. When you open the connection to the VX control station command line interface, you will be prompted to log in log in with your administrator credentials. After you log in change the root user, all the commands described in this demonstration must be executed as route. The first step in the process of changing the IP addresses used by A VX is to stop the proxy ARP service.
The command to do this is shown here. The proxy ARP service supports network communication between the VNX control station and the SP A and S PB storage processors note that stopping the proxy ARP service will not interrupt data mover connectivity or data access by VX users but will interrupt the IP network connectivity between the control station and the storage processors. So after this command is run, you will need to be physically connected to the control station management port through a serial connection to do any management activities on the storage processors.
When you execute the command to stop the proxy ARP service, the system will run several basic checks shown here before starting a 12 step process to shut down the service. The process of shutting down the proxy ARP service includes resetting the SP A and S PB storage processors through the default IP addresses and then shutting down communications to the storage processors. When complete, the system will displace finish along with how long it took to stop the proxy ARP service in larger environments.
This process can take 15 minutes or more. Once the proxy ARP service has been stopped, it is time to set the new IP address for the CS zero control station, the command to set the new CS zero IP address is shown here. If the command rans successfully, the system will return. OK, as shown here. However, note that it may take a few minutes even after the system returns. OK? For the CS zero IP address change to be applied in the active environment.
Next, we need to verify the CS zero IP address has been changed using the NAS cell list command shown here in the output of this command. You should see the new IP address associated with ID zero under net PA as shown here. Next, we will grip for the name of the VNX in the Etsy host file in the output of this command. You should see the new IP address associated with the name of the VNX as shown here.
Next, we need to confirm that the new CS zero IP address is updated in the domain. For both storage processors. You may need to wait 5 to 15 minutes before the domain will be updated to, to do this. We will run the domain list command against both SP A and S PB. The syntax for the domain list command being run against the default SP A IP address is shown here in the output of this command, you should see the new IP address for CS zero associated with the name of the VNX and SP A and S PB at their default IP addresses.
Next, we need to run the domain list command against the IP address for S PB. As shown here again, in the output of this command, you should see the new IP address for CS zero associated with the name of the VNX and the default IP addresses for S PB and S PB. Now you can physically connect the primary VNX control station to the new subnet, the control station network connectors on the back of the control station and is labeled M GMT as shown here to connect to the new subnet, remove the old subnet land cable from the quick connect adapter on the control station and connect the land cable from the new subnet that's connected to an available port for dual control station VX systems.
At this point, you will need to change the IP address of CS. One, this task is not demonstrated in this video, but the steps you will need to do are listed here and except for the fail over step are the same as those for CS zero. The final step in the process of changing the IP addresses used by A VX is to start the proxy AP service. In doing this task, you will specify the new IP addresses used by the VX SP A and S PB storage processors on the new Subnet.
The syntax for this command is shown here. When you execute the command to start the proxy ARP service, the system will run several basic checks shown here before starting a 12 step process to start the service. When complete the system would display, finish along with how long it took to start the proxy ARP service. As a final step, we need to test the VN system at the new IP address, browse to the Unisphere interface at the newly configured IP address and enter the user name and password for your account at the Unisphere log in page as shown here after you login do some vnx management tasks from the Uniter dashboard to confirm that the system is functioning correctly.
Now, let's look at what you need to do to change the IP addresses for a VNX unified array that is being moved to a new IP address within the same subnet. Several of these tasks are the same as in demonstration number one. In the following demonstration, we will demonstrate only tasks three and four of the six tasks required which are listed on this and the following slide. These tasks are task number three, how to change the IP addresses for the SP A and S PB BNX storage processors and task four, how to change the CS zero IP address when moving within the same subnet.
The steps required for task five are listed in demonstration one and task six is demonstrated in demonstration one. Once you have made the physical connection to CS zero and connected to the command line as demonstrated earlier in this video, you can run the modify command to change the IP addresses of the SP A and S PB storage processors. The syntax command is shown here be sure that the new SP A and S PB IP addresses you enter here are within the same subnet as they were previously.
When you execute the modify command, the system will run several basic checks before starting a 14 step process to change the storage process or IP addresses. When complete the system will display, finish along with how long it took to change the IP addresses. After writing the modify command, you should ping the new IP address of SP A to test connectivity and confirm that it responds, then ping the new IP address of S PB and confirm that it responds as well.
Now run the tail command to check the end of the Etsy host file. As shown here. Confirm that SP A and S PB show their new IP addresses. The control station will still show its old IP address. Next run the NAS storage, check all command to confirm, you can discover the VNX storage through the new SP A and S PB IP addresses. The syntax for this command is shown here in larger environments. This command will take several minutes to execute.
If successful the system will return done as shown here. Next check the SP A and S SPB domains. First run the domain list command on the SP IP address as shown here and confirm that the new IP address is displayed for SP and S PB which will show here as a image and B image. The control station should also be listed here with its unchanged IP address. Then run the domain list command on the SPB IP address as shown here and again, confirm that the new IP address is displayed for SP A and S PB.
Now we can change the CS zero IP address by running the NAS CS set command. The syntax for this command is shown here be sure that the new CS zero IP address you enter is within the same subnet as it was previously, which must also be the same subnet as the SP A and S PB addresses. If the command ran successfully, the system will return. OK, as shown here. However, note that it may take a few minutes even after the system returns. OK? For the CS IP address change to be applied in the active environment.
Next, confirm the CS zero IP address has been changed by running the NAS cell. This command is shown here and the command output confirmed that the, the net path shows the new CS zero IP address. Now check the SP A and S PB domains again first run the domain list command on the SP A IP address as shown here and confirm that the control station displays with its new IP address along with the new IP addresses for SP A and S PB.
Then run the domain list command on the S PB IP address as shown here and again, confirmed that the new IP address is display for the control station as well as SP A and S PB. Finally, you should grip for the name of the VNX array in the Etsy host file as shown here. And then the command output confirmed that the VNX array shows the new control station IP address as the final step to confirm the IP address change, test the VNX system at the new IP address by browsing to unisphere as demonstrated in demonstration one, this concludes this video demonstration.
