Contents

Task 1:   Log in to the VPlexcli 3

Task 2:    Disable Call Home if it is enabled. 3

Task 3:   Change the IP address. 3

Task 4:    Re-enable Call Home if applicable. 4

Task 5:   Close the SSH session. 4

Task 6:   Update the RecoverPoint splitter credentials. 4

 


 

Task 1:    Log in to the VPlexcli

                   

  1. [   ]    Using PuTTY (version 0.60 or later) or a similar SSH client, establish a connection to the public IP address of the management server, and log in as user service.

Note:  The EMC VPLEX Security Configuration Guide (available on EMC Support Online) contains the default passwords.

  2. [   ]      From the shell prompt, type the following command to connect to the VPlexcli:

·     If VPLEX GeoSynchrony 4.1 or higher is running on the cluster:

vplexcli

 

·     If GeoSynchrony 4.0.x is running on the cluster, or if you do not know the version:

telnet localhost 49500

 

Log in as user service.

Task 2:      Disable Call Home if it is enabled

                   

  1. [   ]      From the VPlexcli prompt, type the following commands to verify the Call Home status:

cd /notifications/call-home

 

ls

 

Output example if Call Home is enabled:

Attributes:

Name     Value

----     -----

Enabled  true

 

  2. [   ]      If Call Home is enabled, type the following commands to disable it and confirm that it is disabled:

set enabled false --force

 

ls

 

Output example if Call Home is disabled:

Attributes:

Name     Value

----     -----

Enabled  false

 

Task 3:    Change the IP address

                   

  1. [   ]      From the VPlexcli prompt, type the following command:

management-server set-ip –i IP_address:netmask -g gateway_IP_address -p eth3

 

Example :

management-server set-ip –i 10.18.2.0:255.255.255.0 –g 10.18.2.2 –p eth3

 

Note:  Your SSH session to the management server now closes, and you can no longer use the old IP address to the management server.

  2. [   ]    To verify that the address change was successful, establish an SSH connection to the management server’s new address, and log in as service.

Task 4:      Re-enable Call Home if applicable

  If you disabled Call Home earlier in this procedure, type the following commands to enable it and confirm that it is enabled:

set enabled true

 

ls

 

Task 5:    Close the SSH session

                   

  1. [   ]       Type the following command to exit the VPlexcli:

exit

 

  2. [   ]      Type the following command to exit the shell session:

exit

 

Task 6:    Update the RecoverPoint splitter credentials

If RecoverPoint is deployed with this VPLEX cluster, the splitter credentials on each RecoverPoint cluster used with this VPLEX cluster must be updated, supplying the new IP address of the management server.

Before you can update the splitter credentials, you must clear the existing credentials from the RecoverPoint CLI and kill the affinity process.

                   

  1. [   ]    In the RecoverPoint CLI, type the following command to clear the splitter credentials from the RecoverPoint CLI:

clear_splitter_login_credentials

 

  2. [   ]    Type the following command to identify the affinity process on the Site Control RPA:

ps -ef | grep affinity

 

For example:

RecoverPoint_RPA2:/root# ps -ef | grep affinity

 

root      2640     1  0 Apr05 ?        00:00:00 /bin/tcsh ./vplex_affinity_loop.tcsh background

root      2660  2640  0 Apr05 ?        00:06:07 /usr/kashya/java/jre/bin/java -cp /home/kos/kashya/archive/classes/log4j-1.2.15.jar:/home/kos/kashya/archive/classes/orgjson.jar:/home/kos/kashya/archive/classes/java_mpi.jar:/home/kos/kashya/archive/classes/jni_mgmt.jar:/home/kos/kashya/archive/classes/management-client.jar:/home/kos/kashya/archive/classes/log4j-1.2.15.jar:/home/kos/kashya/archive/classes/apache-log4j-extras-1.0.jar:/home/kos/kashya/archive/classes/vplex_affinity.jar com.emc.vplex.discovery.VPLEXDiscovererMain

root     15631 15167  0 05:25 pts/0    00:00:00 grep affinity -

 

 

  3. [   ]    In the output, identify the ID of the vplex_affinity process.

  4. [   ]    Type the following command to kill the process:

kill -9 ID of the affinity process

 

Where ID of the affinity process  is the ID displayed by the grep command.

CAUTION:    Do not kill the vplex_affinity_loop process.

For example:

RecoverPoint_RPA2:/root# kill -9 2660

 

  5. [   ]    After affinity process is back up, re-enter the following information:

·     Splitter credentials

·     New IP address

·     New username and password

When you have completed these steps, the system is ready for the credentials to be updated.

Refer to the RecoverPoint documentation to update the splitter credentials.
