In-band management
Using in-band-management, commands, events, and data travel through the host-to-controller interface. Unlike out-of-band management,
commands and events are mixed with data.
NOTE:
For detailed information about setting up in-band and out-of-band management see your system’s Deployment Guide at
Dell.com/support/manuals.
When you add storage arrays by using this management method, specify only the host name or IP address of the host. After you add the
specific host name or IP address, the host-agent software automatically detects any storage arrays that are connected to that host.
NOTE:
Some operating systems can be used only as storage management stations. For more information about the operating
system that you are using, see the
MD PowerVault Support Matrix
at Dell.com/support/manuals.
Access virtual disk
Each RAID controller module in an MD Series storage array maintains a special virtual disk, called the access virtual disk. The host-agent
software uses the access virtual disk to communicate management requests and event information between the storage management
station and the RAID controller module in an in-band-managed storage array and cannot be removed without deleting the entire virtual disk,
virtual disk group or virtual disk pair. The access virtual disk is not available for application data storage and cannot be removed without
deleting the entire virtual disk, virtual disk group, or virtual disk pair. The default LUN is 31.
Storage arrays
You must add the storage arrays to the MD Storage Manager before you can set up the storage array for optimal use.
NOTE:
You can add storage arrays only in the EMW.
You can:
•
Automatically discover storage arrays.
•
Manually add storage arrays.
NOTE:
Verify that your host or management station network configuration—including station IP address, subnet mask, and
default gateway—is correct before adding a storage array using the Automatic option.
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:
The MD Storage Manager 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 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 Rescan Hosts option in the EMW provide automatic methods for discovering
managed storage arrays.
Manual addition of 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.
