Configuring A Disabled Interface; Using A Dns Server; Editing Dns Settings - HP StoreVirtual 4000 User Manual

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
(page 51).
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 when setting up a management group using the wizard. Make changes to the
DNS settings using the DNS tab for the management group.
The SAN/iQ software uses a DNS server to resolve host names. For example, if you enter a host
name to specify an NTP time server, the specified DNS server resolves the host name to its IP
address.
DNS and DHCP
If you configure the storage system to use DHCP to obtain an IP address, and if the DHCP server
is configured to provide the IP addresses of the DNS servers, then a maximum of three DNS servers
will automatically be added to the management group. These DNS servers are listed as IP addresses
in the management group on the DNS tab. You can remove these DNS servers, but SAN/iQ will
not be able to resolve host names until you enter a new DNS server.
DNS and static IP addresses
If you assigned a static IP address to the storage system and you want the storage system to
recognize host names, you must manually add a DNS server to the management group DNS tab.
NOTE: If you initially set up the storage system to use DHCP, and then change the configuration
to use a static IP address, the DNS server provided by DHCP will remain on the DNS tab. You can
remove or change this DNS server.
