<div>Hi ,</div>
<div><br>
</div>
<div>Phosphor-software-manager currently supports bios upgrade for a single host.I would like to propose a design to add multi host bios upgrade support in Phosphor-software-manager.</div>
<div><br>
</div>
<div>Kindly review the below proposal and share your valuable comments.</div>
<div><br>
</div>
<div>Design:</div>
<div><br>
</div>
<div>a) : Add Host Number</div>
<div><br>
</div>
<div>1) MANIFEST file change:</div>
<div><br>
</div>
<div>Add host number in MANIFEST file, purpose field like below.</div>
<div><br>
</div>
<div>Ex:</div>
<div>For Host1, purpose=xyz.openbmc_project.Software.Version.VersionPurpose.Host1</div>
<div>For Host2, purpose=xyz.openbmc_project.Software.Version.VersionPurpose.Host2 and So on.</div>
<div><br>
</div>
<div>2) For bios upgrade, handle the same to incorporate the host number and send host number to the systemd service obmc-flash-host-bios@service like below.</div>
<div><br>
</div>
<div> if (host.empty())</div>
<div> {</div>
<div> auto biosServiceFile = "obmc-flash-host-bios@" + versionId + ".service";</div>
<div> }</div>
<div> else</div>
<div> {</div>
<div> auto biosServiceFile =</div>
<div> "obmc-flash-host-bios@" + versionId + "_" + host + ".service";</div>
<div> }</div>
<div><br>
</div>
<div>b) : Implement a generic IPMI based multi-host bios upgrade.</div>
<div><br>
</div>
<div>1) This generic implementation expects a json config file with the details like IPMI net function , command id, and etc and process the bios upgrade via ipmi commands.<br>
</div>
<br>
</div>
