Drone Mode SBC Support

14.0Drone Mode SBC Support

An SBC is said to be “drone mode capable” if it can be configured to ignore the PCI_RST# signal coming from the PCI bus when inserted in a peripheral slot in a CompactPCI chassis. In this “drone mode,” the board is operating independently of the PCI bus.

Because it is not acting as a peripheral on the PCI bus, and therefore not dependant on the system master for correct initialization and power up, the normal methods used by the CMM for power sequencing a peripheral board do not apply to the drone board in that PCI segment. This allows two things to occur for drone boards that normally wouldn’t occur for standard peripheral boards:

•A drone mode capable board can be powered up in a peripheral slot without the system master slot being populated and running for that particular PCI segment.

•If the system slot board is extracted/goes unhealthy, the drone mode capable boards in that particular PCI segment should not be powered off.

14.0.1Adding a Drone Mode Capable SBC

The CMM maintains an internal table of drone mode capable SBCs. For the CMM to recognize a drone mode capable board, it must also support IPMI 1.0 or above in addition to being able to operate in a drone mode. To add a drone mode capable SBC to the table issue the following CLI command, substituting the appropriate blade number for N:

cmmset -l bladeN -d IgnoresPCIRst -v 1

Once this command is issued, the CMM will send a GetDeviceID command to the blade and retrieve its manufacturer and product ID. It then adds this information to its internal table of drone mode capable SBCs. That drone mode capable SBC can now be configured to operate in drone mode and placed in any node slot within the chassis thereafter.

The CMM will then treat any board whose manufacturer and product ID match the one listed in the table as drone mode capable.

14.0.2Removing a Drone Mode Capable SBC

To remove a drone mode SBC from the internal table on the CMM, issue the following command:

cmmset -l blade5 -d IgnoresPCIRst -v 0

This removes the listing for that manufacturer and product ID from the internal table on the CMM, and any boards matching this manufacturer and product ID thereafter will be treated as standard CompactPCI system or peripheral boards.
