Changing Shelf Settings Using HPI

How configuration files are created for a new resource

DuringHPIinitialization(whenresourcesarebeingcreatedfortheshelf,slots,andFRUs),

initialdefaultconfigurationfilesareautomaticallycreatedifnonearefoundin

/tmp/shmgr/hpi.Ifnocorrespondingsavedconfigurationfileisfoundfortheresourcein

/var/lib/shmgr,theinitialdefaultconfigurationfi leiscopiedastheinitialsavedconfiguration

file(withthe.hcf.savedsuffix).Youcanlateroverwritetheinitialsavedconfigurationfilein

/var/lib/shmgrtocreateacustomdefaultconfiguration.

Foryourconvenience,theShelfManagermodule’ssoftwareimagealsocomeswithsample

defaultconfigurationfilesforsomeoftheknownFRUsinthesystem,theslotresourcesand

theshelfresource.Thesesampledefaultconfigurationfilesresideinthe/var/lib/shmgr

directoryofthemodule’ssoftwareimage.Notethatthesampledefa ultconfigurationfilefor

slotresources,SLOTS.hcf.deflt,iscopiedasthedefaultconfigurationfileforallslotresources

thefirsttimeaShelfManagermoduleisinitialized.Themoduledoesnothaveany

configurationfilespriortofirstinitialization.

Creating a default configuration file for a new resource

IfanewFRUisinsertedintheshelfandnosampledefaultconfigurationexists(forexample,in

theunlikelyscenariothatdefaultconfigurationfilecreationfailedduringresourcecreation),

thefollowingprocedurecanbe usedtocreateone:

1. InserttheFRUintheshelfandchecktheHPIRPTforitsresource.Thiscanbedoneusing

anHPI1.1‐compliantuserapplication.

2. BeforeanychangesaremadetotheFRU,usethesaHpiParmControl()functionwith:

ResourceId=ResourceIdofthenewly‐createdresource

ParmAction=SAHPI_SAVE_PARM.

Iftheparametercontroloperationsucceeds,a newsavedconfigurationfilewillhavebeen

crea tedin/tmp/shmgr/hpi.Forexample,forresource0xB0090,asavedconfigurationfile

named000B0090.hcf.savedwillbecreated.

3. Renamethe%08X.hcf.savedfileto%08X.hcf.deflt.

Forexample,forresource0xB0090,thesavedconfigurationfile000B0090.hcf.saved

shouldberenamed

ormovedto000B0090.hcf.deflt.ThisnowbecomesthedefaultHPI

configurationfileforthenewresourceandwillbeloadedwhentheparametercontrol

actionSAHPI_DEFAULT_PARMisinvokedontheresourcebytheHPIapplication.
