Disabling A Network Interface; If The Storage System Is In A Management Group; Configuring A Disabled Interface; Using A Dns Server - HP StorageWorks P4000 User Manual

• To ensure that you always have access to the storage system, do not disable the last interface. If
you want to disable the last interface, first enable another interface.
CAUTION:
If you disable an interface, be sure you enable another interface first. That way you always have
access to the storage system. If you disable all the interfaces, you must reconfigure at least one interface
using the Configuration Interface to access the storage system. See
connection" on page 307.

Disabling a network interface

1. Log in to the storage system, and open the tree.
2. Select the TCP/IP Network category.
3. Select from the list on the TCP/IP tab window the interface to disable.
4. Click TCP/IP Tasks, and select Edit.
5. Click Disable Interface.
6. Click OK.
A confirmation message opens. If you are disabling the only interface, the message warns that
the storage system may be inaccessible if you continue.
7. Click OK.

If the storage system is in a management group

If the storage system for which you are disabling the interface is a manager in a management group,
a window opens which displays all the IP addresses of the managers in the management group and
a reminder to reconfigure the application servers that are affected by the update.

Configuring a disabled interface

If one interface is still connected to the storage system but another interface is disconnected, you can
reconnect to the second interface using the CMC. See
manually" on page 86.
If both interfaces to the storage system are disconnected, you must attach a terminal, or PC or laptop
to the storage system with a null modem cable and configure at least one interface using the
Configuration Interface. See

Using a DNS server

You configure DNS at the management group level for all storage systems in the management group.
Use the DNS tab for the management group to change the settings.
The storage system can use a DNS server to resolve host names. For example, if you enter a host
name to specify an NTP time server, the storage system will use DNS to resolve the host name to its
IP address. For example, the time server in Boulder, Colorado has a host name of time.nist.gov.
DNS resolves this host name to its IP address of 192.43.244.18.
