Running The Connection Utility - EMC Unity Family Security Configuration Manual

Communication Security
easier to remember. Since an IP network is based on IP addresses, every time you use
a domain name, the DNS server must translate the name into a corresponding IP
address. For example, the domain name www.Javanet.com translates to the IP
address 209.94.128.8.
No administrative information such as user names, passwords, and such are
exchanged during the DHCP/Dynamic DNS configuration. Configuration of the
management IP items (DHCP preference, DNS and NTP server configuration) fall
under the existing Unisphere framework related to security. DNS and DHCP events
including obtaining a new IP address on lease expiration are recorded in storage
system audit logs. If DHCP is not used for the storage system management IP
configuration, no additional network ports will be opened.
Dynamic IP addresses (DHCP) should not be used for any components of the EMC
Secure Remote Services Virtual Edition (ESRS VE) servers, Policy Manager servers,
or managed devices.
Note
If you use DHCP to assign IP addresses to any EMC Secure Remote Services (ESRS)
components (ESRS Virtual Edition servers, Policy Manager, or managed devices),
they must have static IP addresses. Leases for the IP addresses that EMC devices use
cannot be set to expire. EMC recommends that you assign static IP addresses to
those devices you plan to have managed by ESRS.

Running the Connection Utility

Note
If you are running the storage system in a dynamic network environment that includes
a DHCP server and a DNS server, you do not have to use the Connection Utility and
instead can automatically assign a dynamic IP address (IPv4 only) for the storage
system management interface. When a storage system uses a static IP address, it is
manually configured with the Connection Utility to use a specific IP address. One
problem with static assignment, which can result from a mistake or inattention to
detail, occurs when two storage systems are configured with the same management
IP address. This creates a conflict that could result in loss of network connectivity.
Using DHCP to dynamically assign IP addresses minimizes these types of conflicts.
Storage systems configured to use DHCP for IP assignment do not need to use
statically assigned IP addresses.
Connection Utility installation software is available from the EMC Online Support
website (https://support.emc.com), under the Downloads selection on the menu bar
of the product page for your storage system. After you download the software, install
the program on a Windows host. When you run the Connection Utility from a
computer on the same subnet as the storage system, the Connection Utility
automatically discovers any unconfigured storage systems. If you run the Connection
Utility on a different subnet, you can save the configuration to a USB drive and then
transfer it to the storage system. If the storage system is located on a different
subnet than the host running the Connection Utility, you can select to manually
configure and save IP network and Hostname information to a USB drive as a text file,
then insert the USB drive into either SP, which will then automatically set the IP
network and Hostname information.
