Plan for your backup console
Thistopiccoversbackupconsoleinformationyoumight wantto considerto quickly recoverfromtheunexpectedloss ofyourconsole.Manysystemplans include alevelofredundancytoallowforhardwarefailures,butsomedonot consider theconsoleinthose plans.Here aresomesuggestionsifyouwouldliketo planfora backupforyour console:
OperationsConsole, bothdirectattached andnetwork(LAN)andtwinaxial workstations cancoexist asconsoledevicesif youremembertheserules:
v Onlyonedevicecanbeactiveata time.Anactiveconsoleisa command interfacetoaniSeriesserver(5250emulation) thatiscurrentlyinteractingwith theserver.
v Atwinaxialworkstationonanytwinaxialworkstationcontrollerwithport0 (address0or1 orwithport1 (address0 or1)canbea consoledevice.
v Topreventinteractionsbetweeneligibleconsoletypes,be sureyoudonothave morethanoneworkstationavailable duringanIPL.Topreventa deviceenabled asan OperationsConsolefrombecomingtheconsole,youneed todisconnect anyactiveconnectionsandleaveitdisconnectedduringtheIPL.Fortwinaxial workstations,it issuggestedthatyoupowerofftheworkstation.Notethaton somemodelstheon/offswitch actuallyonlypowersoffthedisplayportionof theworkstationandtheworkstationelectronicsarestillactive,whichwould allowthedevicetobecometheconsole.Ifyouare notsure,removethepower cordfromtherearoftheworkstation.
v Forindependentand primarypartitions,multipleIOPscapableof supportinga consoleworkstationcaninterferewiththeselectionofthedesiredLAN adapter.
Considerthefollowing:
– Havinga 2ndIOPonthebusbeforeyour intendedconsoleadaptercard, whenthefirst IOPcontainsa twinaxialadaptercard,willfailtoprovidea LAN-connected console.Forexample,a model890useseligiblecardlocations C04, andC06throughC10andifanIOPwereplacedinC08anda twinaxial adapterprecededthis IOPonthebusthentheLANadaptercardlocatedat C09orC10willfailtoprovidea LAN-connectedconsole.TheLAN adapter cardmust beina locationpreceding the2nd IOP,suchasC06orC07.
– Typically,thecardlocationusedforOperationsConsoledirectlyattached configurations,commonlyreferredtoastheECSslot,islocatedclosetothe beginningofthebus. Whenthecardlocationisa lownumbersuchasC02, then C03isfartherfromthebeginningofthebusthanC02.Whenthecard locationisahighernumber suchasC07, thenC06isfartherfromthe
beginningofthebusthanC07.Thismaynotbe trueforall modelsand expansionunits.Whenindoubtcontactyour servicerepresentative.
Considerationsfora backupconsole:
v Theadapterlocationisfixed oratleastlimited forindependentserversor primarypartitions.Basedonyourserver’s hardwarerequirementsyoumayhave limitedchoicesofconsoletypes.Trytoaccommodate atleastoneadditional consoletype,if possible.
v Forsecondarypartitionsconsider:
– IfyouplantouseOperationsConsoleastheprimaryconsoleorabackup, youmusttagtheIOPtosupport theprimary consoleandElectronic Customer Support,evenifyoudonotplantouseElectronicCustomer Support.YoucannottagseparateIOPsforanOperationsConsole, regardless ofconnectivity, andElectronicCustomerSupport.
– InanLPAR environment,theterm alternateconsoleisreferringtoaconsole type locatedinanotherIOPtaggedasthealternateconsole.Ifa failureofthe primary consoleisdetected,thesystem willautomaticallytrythealternate console’sIOP.Thisgivesyouanotherlevelofprotection. However,tagging a single IOPasboththeprimaryconsoleand thealternateconsolewillnot provideadditionalprotectionandcancauseproblemsassigningtheprimary console. Furtherisolationcanbe plannedbyplacingthealternateconsoleIOP ona differentbussothatfailures oftheprimaryconsole’sbuswillnot preventa consolefrombeingavailable.
– Thecurrentimplementationfortagginga consoletype isonlyattheIOP level. PlacingtwonetworkadaptersforthesameIOPcansometimesmakeit difficult todetermine,inadvance,whichnetworkadapterwillbe usedforthe console. IBMrecommendsonlyonenetworkadapterfortheIOPtaggedas theprimaryconsoletosupportOperationsConsolelocalconsoleona network.
– Consider ashared resourceenvironment inwhichyoucanallocateand deallocatea consolesupportingIOPtoa partitiononapart-timebasis.Many workenvironmentsrarelyneedaconsoledeviceonafull-timebasisandyou canreduceyourinitial costofdedicatedhardwarebyimplementing this concept.
– Iftheloadsourcestoragedevicefailsandthesystemrecovery willinclude theuseoftheIBM distributionLicensedInternalCodemedia insteadofa customer backup,andthesystemisusingOperationsConsole(LAN),you mayhavetouseanotherconsoletype fortheinitial portionofthesystem recovery.
Planning configurationtypesforadditionalbackupconsoles:
Note: IfyouplantouseOperationsConsolelocalconsoleona network(LAN) as abackuptoanotherconsoletype,youmust havetheconsoletypeset to OperationsConsole(LAN)and havetheassociatednetworkadapter configuredpriortoneedingthisdevice.SettingtheconsoletoOperations Console(LAN) doesnotpreventanOperationsConsole(direct)or twinaxial frombecomingtheconsoleduring anIPL.Justmakecertainonlyone consoletype isavailable duringtheIPL.
Backupconsoleconfiguration types:
v Ifyourserverisaccessedremotely,consideroff-siteconsolecapabilityoranother connectivityfortheconsole.Alocalconsoleonanetworkcanbebackedupwith additionallocalconsoleona networkPC. Ifthenetworkadapterwereto fail, considera localconsoledirectlyattachedtotheserverasa backup.By changing
theconsoletypetoa localconsoledirectlyattachedtotheserverwithremote access,youcanaddtheabilityforaremote PCtobecometheconsole.
v Inan LPARormultipleserverenvironment youwillmostlikelybeusing multiplelocalconsoleona networkconfigurationsona singlePCasyour primaryconsoles.Consider additionalPCsusingthissametype configuration.
AvoidsupportingtoomanyconsolesonthesamePCifpossible.ThePC resourcescanbeeasilyoverwhelmedwhensupportingmultipleconsolesand remotecontrolpanels.
v Considermultiplelocalconsoleonanetworkconfigurationsinlarge
environmentssothateachPChasacoresetofconsoleresponsibilitiesandthe overlapcoverageof backupconfigurationswith eachother.For example,ifyou havea PCthatsupports10localconsolesonanetworkconfigurationand anotherPCwith thesame numberofprimaryconsolesforanother10partitions, insteadofbackingupeachPCwiththeother’sconfiguration, youaddathird PCand spreadthe20consolesoutsothattwoPCsbackupaportionofeach PC’sprimaryconsoleconfigurations.AnotherconsiderationisadedicatedPCto bethebackupofacertainnumber ofconsolesbutisnotusingituntil necessary.
v Whenusingmostlynetworkedconsoles,considersettingupalocalconsole directlyattached totheserverona PCand placeitona rollawaycartwitha consolecable.Ifyouhavesupportingadapters,youcanquickly rollthecart withthePCnear theserverorpartitioninneedof theconsole.Afterconnecting thecable,andactivatingtheline,youhavea consoletoreplace thecurrently failedconsole.Thissameconceptcanbe implementedfortwinaxialworkstations justaseasily.
Note: Ifmorethanonelocalconsoleona networkisplanned,be certaintocreate additionalservicetoolsdeviceIDsontheserverbefore youstart configuring theOperationsConsolePC.EachPCconnectingtothesametarget serveror logicalpartitionmust haveauniqueservicetoolsdeviceID.
Insummary,considerasmuchredundancyaspossibleforyour consoleneeds.
