HP StoreEver ESL G3 Tape Libraries - Manual (Page 48)

NOTE: For newer libraries with the MCB Version 2 and using library firmware revision 680H
or later, the menu dialog will be Setup
→Network Configuration→Interface 1 and
Setup
→Network Configuration→Interface 1, for the two Ethernet ports on the MCB 2,
respectively.
•
If IPv6 is disabled, the IPv4 Network Configuration dialog box appears.
Proceed to “Setting up IPv4 network configuration” (page 42) .
•
If IPv6 is enabled, but you want to configure an IPv4 connection, click IPv4 Configuration
on the Network Configuration submenu to display the IPv4 Network Configuration dialog.
Proceed to “Setting up IPv4 network configuration” (page 42) .
•
If IPv6 is enabled and you want to configure an IPv6 connection, click IPv6 Configuration
on the Network Configuration submenu to display the IPv6 Network Configuration dialog.
Proceed to “Setting up IPv6 network configuration” (page 44) .
NOTE: The Network Configuration submenu only appears if you have enabled IPv6 for the
physical library.
After you set up the network configuration, see the following topics:
•
“Setting up IPv4 network configuration” (page 42)
•
“Setting up IPv6 network configuration” (page 44)
Changing internal IP network addressing
You can use the LMC to change the internal IP address of the library and other library security
settings, including enabling or disabling network services, enabling or disabling remote access to
the library, setting up firewall access for server callbacks to remote clients, and enabling or disabling
SNMP or SMI-S access.
The default internal network subnet setting for the ESL G3 library is 10.10.X.X. Attaching the library
to a 10.10.X.X external network can cause library and network problems. The Change Internal IP
dialog box enables you to change the library internal IP addressing so that conflicts do not occur.
This dialog box is accessible only from the library OCP.
•
You only need to change the default internal IP setting if your external network is 10.10.X.X.
•
Do not set up internal IP addressing to conflict with existing external IP addressing. If you set
up the same IP subnet for both the internal and external IP networks (for example, 10.10.X.X),
the library will become unusable.
•
If you change the internal IP addressing, and then later on a user uses the Network
Configuration dialog box (Setup
→Network Configuration) to assign to the library a static IP
address that conflicts with the internal network, the assignment request will fail and the library
will issue an event.
•
If you change the internal IP addressing, and then later on a user uses the Network
Configuration dialog box (Setup
→Network Configuration) to assign to the library a static IP
address that conflicts with the internal network, the assignment request will fail and the library
will issue an event.
•
If you change the internal IP addressing, and if Dynamic Host Configuration Protocol (DHCP)
is enabled and DHCP assigns to the library an IP address that conflicts with the internal network,
address conflicts could occur between internal library devices and external customer devices
and the library will issue an event.
To change the Internal IP Network Addressing:
1.
Make sure that you are viewing the physical library. From the View menu or in the Managed
Views region of the LMC, click the name of the physical library.
