Is the storage system configured to use
the DHCPv4 server?
When the storage system is configured to
use a DHCPv4 server, use the IP
addresses assigned by the DHCP v4
server. When using a DHCP v4 server, we
recommend you configure the storage
system to use static IP addresses.
If the IP address is not assigned by a
DHCP v4 server, but the storage system
is configured to use DHCP v4 server-
supplied IP addresses, Storage Navigator
Modular 2 will not be able to connect to
the storage system. Consult your
administrator and review the DHCP v4
server settings.
[default value]
DHCP v4:Off (Static IP Address)
Is the IP address of the storage system
assigned to other storage systems or
hosts?
If a storage system uses the same IP
address used by other storage systems
and hosts, Storage Navigator Modular 2
cannot connect to the storage system.
Assign different unused IP addresses to
the storage system.
Are the correct values set for the IP
address, subnet mask, or default
gateway of the host where Storage
Navigator Modular 2 is installed?
Set the IP address, subnet mask and
default gateway that allows the storage
system to communicate with the host.
Is the network switch performing TCP/
UDP port filtering?
The default TCP port number for Storage
Navigator Modular 2 is 2000. Set a
suitable value for the customer
environment.
[the default port
number]:2000(standard) 28355(secure)
Change the port number in environments
that use the Cisco SIP Phone.
Is the Search Array function being
performed across the IPv6 routers?
The Auto Search Array used by IPv6 uses
link-local scope multicast. The IPv6
router cannot transfer this multicast to
other local links, so the IPv6 router is
unable to search the storage system
across the IPv6 router. If different local
links are used, register the storage
system using a static IP address search.
Is packet filtering enabled?
There may be times when a connection to
the storage system cannot be made
temporarily. Wait at least one minute,
and then update it again.
