5.7.2.3 System Manager
If the system manager accesses the active shelf manager via the backplane Ethernet interfaces
it may use virtual IP Plane and active virtual IP address 192.168.20.171 of the shelf manager.
To detect where the active shelf manager is located the system manager can use the following
techniques:
z
Inside the AdvancedTCA shelf
The system manager pings via both Ethernet interfaces to the active virtual IP address of
the shelf manager to identify in which slot the active shelf manager is located.
z
Inside the AdvancedTCA shelf
The system manager uses IPMI commands to identify in which slot the active shelf
manager is located:
— The
Get Address Info
command to IPMB address 0x20 (in its 1-byte-request data
variant) to get the hardware address of the shelf manager.
— Read the 'Backplane Point-to-Point Connectivity' record of FRU ID 254 of the shelf
manager for the base interface and analyze the shelf manager's interface connection
to the hub blade.
— Check whether the correspondent hub blade is present and active (M4 or M5 state).
The system manager knows that the base channel #1 of the AdvancedTCA front blade
is connected to the Hub #1 and the base channel #2 of the AdvancedTCA front blade
is connected to the Hub #2, and assigns the virtual IP address to the proper interface.
z
Outside the AdvancedTCA shelf with interlinks between the hub blades
The system manager pings via its own active IP address to the active virtual IP address of
the shelf manager.
