1 Overview
Thegoalofthispaperistoprovideeasy-to-readinstructionstoquicklyupdatesystemfirmwareonp5servers. Itisassumedthereaderhasbasicp5skills. Thereareextensivereferencesthatshouldhelpwithitemsnotcoveredinthispaper.
Threefirmwareupdatemethodswillbecovered:
1.UpdateonanHMCmanagedsystem
2.Updateonastandaloneservervia OS,withoutaHMC
3.UpdateonastandaloneserverusingtheDiagnosticCD,withoutaHMC

1.1 p5serverhardware
Thehardwareusedindevelopingthispaperwasap5550Q（type-model9133-55A）. HMC（version5.2.0includingfixMH00586）wasalsousedwhenneeded.
1.2 Systemfirmwarefixesandupgrades
Firmware,alsoknownasmicrocode,isLicensedInternalCodethatfixesproblemsandenablesnewsystemfeaturesastheyareintroduced. Newfeaturesintroducedaresupportedbynewfirmwarereleaselevels. Inbetweennewhardwareintroductions,therearefixesorupdatestothesupportedfeatures. Thesefixesareoftenbundledintoservicepacks. Aservicepackisreferredtoasanupdatelevel. Anewreleaseisreferredtoasanupgradelevel. BothlevelsarerepresentedbythefilenameintheformofPPMMXXX_YYY_ZZZ. PPandMMarepackageandmachinetypeidentifiers. PPcanbe01formanagedsystemoritcanbe02forpowersubsystem. TheMM identifierisaSFforp5systemsandaBPforBulkPowerController. Thefirmwareversionfileapplicabletop5machinesisintheformof01SFXXX_YYY_ZZZ.
1.3 Decodingfirmwarenames
Thefilenamingconventionforsystemfirmwareis:
01SFXXX_YYY_ZZZ,where
XXXisthestreamreleaselevel
YYYistheservicepacklevel
ZZZisthelastdisruptiveservicepacklevel
Usingtheaboveexample,thesystemfirmware01SF235_185wouldbedescribedasreleaselevel235,servicepack185.
Eachstreamreleaselevelsupportsnewmachinetypesand/ornewfeatures.
Firmwareupdatescanbedisruptiveorconcurrent.Adisruptiveupgradeisdefinedasonethatrequiresthetargetsystemtobeshutdownandpoweredoffpriortoactivatingthenewfirmwarelevel. Anewreleaselevelupgradewillalwaysbedisruptive. Allotherupgradesaredefinedasconcurrent,meaningthattheycanbeappliedwhilethesystemisrunning. ConcurrentupdatesrequireanHMCbutarenotguaranteedtobenon-disruptive.
Ingeneral,afirmwareupgradeisdisruptiveif
1. Thereleaselevels（XXX）aredifferent.
Example:
CurrentlyinstalledreleaseisSF230,newreleaseisSF235
2. Theservicepacklevel（YYY）andthe lastdisruptiveservicepacklevel（ZZZ）areequal.
Example:
SF235_180_180isdisruptive,nomatterwhatlevelofSF235iscurrentlyinstalledonthesystem
3. Theservicepacklevel（YYY）currentlyinstalledonthesystemislowerthanthelastdisruptiveservicepacklevel（ZZZ）ofthenewservicepacktobeinstalled.
Example:
CurrentlyinstalledservicepackisSF235_180_180and thenewservicepackisSF235_190_185
Aninstallationisconcurrentif:
1. Theservicepacklevel（YYY）ishigherthantheservicepacklevelcurrentlyinstalledonyoursystem.
Example:
CurrentlyinstalledservicepackisSF235_180_160,newservicepackisSF235_185_160.
1.4 Decodingtheoperatorcontrolpanel
Whenthesystemispoweredon,notetheoperatorcontrolpanel. Itshouldappearsimilartotheimagebelow.

HMC=1 T
InthisexamplethesystemiscurrentlybootedfromthetemporarysideofthefirmwareimageasdenotedinthecontrolpanelbytheletterT. Thisindicatesthefirmwareisrunningfromthetemporaryside. Nindicatesthesystemisbootedinnormalmode. V=FindicatesthebootspeedissettoFast. HMC=1indicatesthattheserverismanagedbyandconnectedtooneHMC.
IfithasbeenrecentlymanagedbyanHMCandnoHMCisconnectedthenitwilldisplayHMC=0. IfnoHMCisavailableanditisdesiredtosettheservertounmanageditmightberequiredtoresettheserviceprocessortofactorydefaultusingASMI.
1.5 TemporaryversusPermanentFirmwaresides
TheServiceProcessormaintainstwocopiesoffirmware,thetemporaryandpermanentside,tohelpmanageandreducethefrequencyofdowntimeformaintenance. Thepermanentsideisalsoknownasthe"P"side. Thetemporarysideisalsoknownasthe"T"side. Serverfirmwarefixesareinstalledonthetemporaryside. Copyingthetemporaryfirmwareleveltothepermanentsideisknownascommittingoracceptingthefix.Conversely,rejecting,orremovingthecurrentfirmwarelevelconsistsofcopyingthepermanentfirmwareimagetothetemporaryside.
Note:
Itisrecommendedtouseanewfirmwarefixforaperiodoftimebeforecommitting（oraccepting）it.
Iffirmwarefixesareappliedconsecutively,thefirstfixwill,bydefault, becopied fromthetemporarytothepermanentside,oraccepted. UsinganHMC,itispossibletosimplyreplacethetemporaryimagebydoinganInstallandActivateofthenewfirmwareandindicatingthatthefirmwareshouldnotbeaccepted.
