This section will walk you through pre-installation hardware setup, if any, that you will need to do prior to installing Debian. Generally, this involves checking and possibly changing BIOS/system firmware settings for your system. The “BIOS” or “system firmware” is the core software used by the hardware; it is most critically invoked during the bootstrap process (after power-up).
Der er et uddrag fra IBM PowerKVM on IBM POWER8.
Open Power Abstraction Layer (OPAL) er systemfirmwaren i stakken af POWER processor-baserede servere.
Der kan være tilfælde, hvor brugeren skal opgradere Power Systems-firmwaren til en nyere version for at kunne bruge nye funktioner eller få yderligere understøttelse for enheder.
Sikr dig at de følgende krav er opfyldt:
et operativsystem er aktivet på systemet;
.img-filen for OPAL-niveauet som brugeren skal opdatere til;
maskinen ikke er under HMC-kontrol.
Power Systems has two sides of flash to boot firmware from, namely permanent and temporary. This provides a way to test firmware updates on the temporary side of the flash before committing the tested changes to the permanent side, thereby committing the new updates.
Udfør de følgende trin for opdateringen:
Gem niveauet for den eksisterende firmware før du udfører den faktiske opdatering. I ASM, i systemmenuen, klik på Service Aids -> Service Processor Command Line, og afvikl den følgende kommando:
cupdcmd -f
Hent .img-filen for det niveau af firmwaren, der skal opdateres, til en placering i værtsfilsystemet. Se IBM Fix Central for hvordan filen hentes.
Verificer det hentede aftryk ved at afvikle den følgende kommando og gemme resultatet.
$update_flash -v -f <file_name.img>
Opdater firmwaren ved at afvikle den følgende kommando.
$update_flash -f <file_name.img>

---|---|

Verificer det opdaterede firmwareniveau for den midlertidige side af flashen som i trin 1.
In case the update has to be reverted, the user can do so by running this command:
$update_flash -r
Rejection would reject only the temporary side of the flash. Therefore, the new level should be committed to the permanent side only after thorough testing of the new firmware.
Det nye opdaterede niveau kan anvendes på den permanente side af flashen ved at køre den følgende kommando.
$update_flash -c
Slimline Open Firmware (SLOF) is an implementation of the IEEE 1275 standard. It can be used as partition firmware for pSeries machines running on QEMU or KVM.
The package qemu-slof is, in fact, a dependency of package qemu-system-ppc (which also provides the virtual package qemu-system-ppc64), and can be installed or updated via apt tool on Debian-based distros. Like so:
# apt install qemu-slof
SLOF can also be installed into rpm-based distribution systems, given the proper repository or rpm package. Additionally, the upstream source code is available at http://github.com/leilihh/SLOF.
Thus, one can use a different SLOF file rather than the default, when running qemu-system, by adding the command line argument -bios <slof_file>
when starting qemu.
Du skal bruge en DHCP/TFTP (BOOTP)-server, samt en internetserver. Efter du har hentet ibm-powerkvm-*-ppc64-service-*.iso, monter loop aftrykket og pak det ud i en mappe indenfor din HTT-servers www root-struktur (f.eks. wwwroot):
# cd <directory-where-the-iso-is> # mkdir ./iso # sudo mount -o loop ibm-powerkvm-*-ppc64-service-*.iso ./iso # cp -a ./iso/* <path-to-wwwroot>
Opret filen petitboot.conf file i en mappe under din tftproot, f.eks. /tftproot/powerkvm, med det følgende indhold:
label PowerKVM Automated Install kernel http://YOUR-SERVER-IP/SOME-PATH-TO-wwwroot/ppc/ppc64/vmlinuz initrd http://YOUR-SERVER-IP/SOME-PATH-TO-wwwroot/ppc/ppc64/initrd.img append root=live:http://YOUR-SERVER-IP/SOME-PATH-TO-wwwroot/LiveOS/squashfs.img repo=http://YOUR-SERVER-IP/SOME-PATH-TO-wwwroot/packages rd.dm=0 rd.md=0 console=hvc0 console=tty0
Redigering af din dhcpd.conf, angiv dette direktiv i begyndelsen:
option conf-file code 209 = text;
Tilføj systemdirektivet:
host <your-system> { hardware ethernet <system macaddr> fixed-address <system ip>; option host-name "<system hostname>"; option conf-file "<powerkvm/petitboot.conf>"; }
Genstart dhcp-serveren.
Start din PowerLinux-maskine op.
Der bør være den følgende indstilling med petitboot (vælg den):
"Power KVM Automated Install"
Installationsmenuen kommer frem automatisk.
