Configuration: About Your Storage Array 67
NOTE: For Linux, set the default gateway so that broadcast packets are sent to
255.255.255.0. For Red Hat Enterprise Linux, if no gateway exists on the network, set
the default gateway to the IP address of the NIC.
NOTE: MDSM uses TCP/UDP port 2463 for communication to the MD Storage
Array.
Automatic Discovery of Storage Arrays
The Automatic Discovery process sends out a broadcast message across the
local subnetwork (subnet) and adds any storage array that responds to the
message. The Automatic Discovery process finds both in-band and out-of-
band storage arrays.
NOTE: The Automatic Discovery option and the Re-scan Hosts option in the
Enterprise Management Window provide automatic methods to discover managed
storage arrays.
Manual Addition of a Storage Array
Use Manual Addition if the storage array resides outside of the local subnet.
This process requires specific identification information to manually add a
storage array.
To add a storage array that uses out-of-band management, specify the host
name or management port IP address of each controller in the storage array.
Before using this option, verify that the applicable network configuration
tasks are performed.
To add an in-band storage array, add the host through which the storage array
is attached to the network.
NOTE: It can take several minutes for MDSM to connect to the specified storage
array.
To add a storage array manually:
1
Select
Edit
Add Storage Array
.
2
Select the relevant management method:
•
Out-of-band management
—Enter a host name or an IP address for
the

in the storage array.
•

—Enter a name or an IP address for the
Host
through which the storage array is attached to the network.
