Architectures/PowerPC/Infrastructure

These are not the droids you're looking for
This information is for the Fedora for Power and Fedora Infrastructure teams only. Access to these systems is highly restricted

Fedora for Power currently has all of its infrastructure located on two physical hosts, each running multiple LPARs:

ppc-comm03

• Hypervisor: PowerVM
• VIOS: ppc-comm03.qa.fedoraproject.org
• ASM: ppc-comm03-mgmt.qa.fedoraproject.org

Hostname	LPAR Name	LPAR ID
ppc-hub.qa	hub	3
ppc-composer.qa	composer	4
ppc-builder1.qa	builder1	2
ppc-builder2.qa	builder2	5
ppc-builder3.qa	builder3	6
ppc-builder4.qa	builder4	7

• Note that builder4 is kept updated, but is normally turned off and inactive to allow the rest of the hosts on the system to have more CPU and I/O bandwidth

ppc-comm04

Hypervisor: PowerVM VIOS: ppc-comm04.qa.fedoraproject.org ASM: ppc-comm04-mgmt.qa.fedoraproject.org

Hostname	LPAR Name	LPAR ID
ppc-builder5.qa	builder5	2
ppc-builder6.qa	builder6	3
ppc-builder7.qa	builder7	4
ppc-builder8.qa	builder8	5
ppc-releng.qa	releng	6

• The builder8 lpar exists but has not been installed to
• releng is a not a production "system", it's used for install testing and miscellaneous tasks as needed.

ppc-comm05

Hypervisor: PowerVM

ppc-comm06

Hypervisor: KVM

ppc-comm07

Hypervisor: KVM

ppc-comm08

Hypervisor: KVM

Handy VIOS Commands

• Immediately restart a system:

chsysstate -o shutdown -r lpar --immed --restart -n [LPAR name]

• Attach a serial console:

mkvt -id [LPAR ID]

To quit the console while you're in it, use "~.[ENTER]"

• Unattach someone else's serial console:

rmvt -id [LPAR ID]

• List all LPARs on the system (and only display LPAR name and ID):

lssyscfg -r lpar -F lpar_id,name

• Create virtual media from an ISO and attach it to a system:

mkvopt -name Fedora-18-20120830-Hamzy-ppc64-DVD -file Fedora-18-20120830-Hamzy-ppc64-DVD.iso -ro
loadopt -disk Fedora-18-20120830-Hamzy-ppc64-DVD -vtd vtopt4 -release

Use 'lsmap -all' to figure out which LPAR has which vtopt device.
