Always review the latest version of the Virtual Connect Release Notes which contains any prerequisites. The v3.61 release
notes can be found in the “Getting Started” section of the following URL:

Capturing the Existing VC 1/10 Domain Configuration
The Virtual Connect CLI interface provides a simple way to obtain the domain and server profile configuration. Using an SSH
client such as PuTTY, it is possible to log the output of the VCMCLI commands needed to capture the existing domain
settings and configuration.
Connect to the Virtual Connect Manager CLI using an SSH Client such as PuTTY. Enable logging on the SSH client to capture
the output from the session.
Run the following commands, saving each output in a separate text file. The –includepoolinfo option is available in VC v3.61
and VC 4.20 and later.
SHOW CONFIG -includepoolinfo
SHOW DOMAIN
SHOW SERVERID
SHOW PROFILE *
Note
Ensure the asterisk in the SHOW PROFILE * command is included at the end of the command to capture all profile settings
The information from the “SHOW CONFIG –includepoolinfo” SSH log file will be used to configure the new modules, as
described in this document. Therefore pay close attention to modifications. The other files are not used in the migration
process, but will be used to provide a comparison of the configuration before and after migration if necessary.
Creating a Script Configuration for New VC Flex-10/10D Domain
The first step in creating a configuration script for the planned Virtual Connect Flex-10/10D domain is to modify the SHOW
CONFIG output file. This file is the main configuration script to configure the new domain with the Flex 10/10D modules. If
you have existing VC Fiber Channel modules in the chassis that will continue to be used for fiber channel storage, they may
remain in the chassis throughout this process.
Edit the captured file and remove any text before the “#### IMPORT ENCLOSURE(S) FIRST” line. Only the VCM CLI scripting
commands should remain in the file. Remove any other text after the final “ASSIGN PROFILE” command at the end of the
config script.
Modifying User Credentials
The SHOW CONFIG output does not display the existing passwords of any users defined for the domain. To incorporate user
accounts and passwords in the configuration script modify the highlighted portion of the script to use the correct password
strings for each local user account. The Administrator account is built in, and will not be displayed in the SHOW CONFIG.
### Password for user : 'admin' set to 'changeme'
add user admin Password=changeme Enabled=true Privileges="domain,network,storage,server"
### Password for user : 'net-admin' set to 'changeme'
add user net-admin Password=changeme Enabled=true Privileges="network"
This step may also be done manually after the domain is established through the Virtual Connect Manager GUI or CLI if
placing passwords in a configuration script is not desirable.
Modifying SSL Strength Setting Command
The SHOW CONFIG output will display the current SSL setting. In order for the SSL setting command to run in the script
without user interaction, the –quiet option must be added to this line. If the line is left unmodified, the script will stop and
prompt for SSL setting confirmation.
