Automatic Discovery fails on an
IPv4 subnetwork
Do I need to configure both
management ports on dual-
controller (duplex) storage array?

access to the owning RAID
controller fail

module to determine whether a fault condition is
indicated.
Automatic discovery of storage arrays is not
supported on IPv4-enabled subnets. Verify the
following:
you can successfully ping the management
-
ports on the storage array
the management ports are on separate
-
subnets than your management station
If both are true, manually add the storage array(s)
to MD Storage Manager (see Manually Adding a
Storage Array to MD Storage Manager).
A dual-controller storage array is considered
partially managed if only one of the two available
Ethernet management ports are configured. Many
management commands require access to both the
owning and non-owning RAID controller module --
for example, IP configuration or virtual disk
creation. To fix this issue, repeat discovery
(automatic or manual) and configure the second
management port.
NOTES:
Partially managed storage arrays can have
-
alternate paths added through both auto-
discovery and manual configuration. See
Manually Adding a Storage Array to the
Management Software View.
If you are able to ping a RAID controller module
-
but not perform management operations, it
may be in Lockdown state. See RAID controller
in Lockdown mode.

A management port may show as Disconnected for
a number of reason. Common causes are:
automatic discovery failed because your

management station is connected to a non-
networked switch with a single data path the


faulty cable/physical connection

In cases of replacement or upgrade, you may need
