QA

mgriessmeier found http://dist.suse.de/IBM/HMC.power.10.1.1010/ . powerhmc3 is running on the morla virtualization cluster maintained by Eng-Infra. Maybe we can ask to copy that to prg2 or ask eng infra for new VM and then just deploy from the mentioned directory. According to mgriessmeier BuildOps does not need HMC, maybe they have a better solution we can use as well, ask jdsn. Discussed with mgriessmeier, maybe QE Kernel can help to push this forward.

Meeting with jford, mcaj, horon, mgriessmeier, gpfuetzenreuter. We decided into which racks the PowerPC in PRG2 should go. There are two racks planned for LSG QE:

• PRG2-J11 for QE&openqa.suse.de
• PRG2-J12 for openqa.opensuse.org

We added the according racks in
https://mysuse.sharepoint.com/:x:/r/sites/DatacentreTransformation/_layouts/15/Doc.aspx?sourcedoc=%7B4B68F941-C7EC-431A-B3CF-875DBBCC6C83%7D&file=2023-01-16_2023Q1_PowerPC_capacity_planning_-_WIP_v0.7.0_jf.xlsx&action=default&mobileredirect=true&DefaultItemOpen=1
For the multiple "QE but not openQA" machines no specific place was planned within the QE/openQA racks so far but we have some space available so we planned all those PowerPC machines to go to PRG2-J11 as well. If there is not enough space those machines can move to other spare racks based on consideration by Eng-Infra

horon provided two links regarding HMC setup that might help:

Trying HMC installation on osiris-1.qe.nue2.suse.org:

cd /var/lib/libvirt/images/hmc
wget -c http://dist.suse.de/IBM/HMC.power.10.1.1010/HMC10.1.1010.0-2108131106-x86_64.KVM.tgz -O - | tar -xzpf -
ln -s /var/lib/libvirt/images/hmc/domain.xml /etc/libvirt/qemu/ibm-hmc-power-10.xml

and multiple adjustments in the machine definition XML file until virsh create /etc/libvirt/qemu/ibm-hmc-power-10.xml succeeded. I then connected using virt-manager and watched the system boot. Eventually an ncurses wizard starts up where you need to accept multiple times, then an X session with a wizard starts. I am setting "susetesting" as password for relevant users and an "okurz" user with my personal password.

After the wizard the X session with internal firefox starts a connection to the usual HMC web interface. The VM has mac 52:54:00:49:88:12 so from walter1.qe.nue2.suse.org I could find the address as 10.168.193.43. I then managed to actually add power8 with the current IPv4 address 10.168.193.46 but the HMC showed something about "version mismatch" which I think we have seen in the past already.

I tried to access the HMC web interface from outside but seems a firewall blocks me. The wizard offered to configure the firewall and I denied assuming then that there would be no firewall but likely there is. I wonder if I can restart the wizard or something.

Played a bit with the HMC together with nicksinger and mkittler. In the local HMC web interface in "Console Management>Console Settings>Change Network Settings>LAN Adapters>Details>Firewall Settings" we clicked "Allow Incoming" for both "Secure Shell" and "Secure Remote Web Access" which allowed remote access. But then we found that the machine is not reachable anymore because somehow no gateway address is set. For now in "Console Management>Console Settings>Change Network Settings>Routing" we set a manual gateway entry with gateway address 10.168.195.254. Now we can login over https://10.168.193.43 remotely. We can't use an FQDN as there are some holes in the DNS config for qe.nue2.suse.org, fixing that with https://gitlab.suse.de/OPS-Service/salt/-/merge_requests/3741

Next physical move preparation planned for 2023-08-30, mgriessmeier and mmoese will be physically present in NUE1-SRV2 and prepare the move of next wave machine

I wrote in https://suse.slack.com/archives/C04MDKHQE20/p1693215411497969

@Héctor Orón @Moroni Flores @John Ford @Matthias Griessmeier because there were questions: We clarified that the machine "macbeth" is what we call "grenache" which is not what racktables.nue.suse.com/ knows as "macbeth" which is a different machine. grenache is planned to be moved this week so Matthias with help from others will prepare it for the physical move from NUE1-SRV2. As we still do not have any HMC available from PRG2 for the machines from 1st wave I see a significant impact on PowerPC availability for openQA related testing. Any HMC related work should be expedited accordingly

EDIT: According to DM from mgriessmeier HMC should be ready by tomorrow(?).

following qe machines have been packed into boxes which will be picked up by proact (moving company) tomorrow (31-08-23) and transferred to prague.

• whale
• QA-power8-3
• grenache
• cloudberry
• soapberry
• huckleberry
• redcurrant
• blackcurrant

all machines have been moved in racktables into a "transit-rack" -> https://racktables.suse.de/index.php?page=rack&rack_id=24497

gschlotter provided me credentials for a new HMC. I logged in as "hscroot" and setup accounts for everybody that was already existing on powerhmc3.arch.suse.de including "okurz" and "openqa" and to all human operators I send a private message with

The new LSG-QE PRG2 PowerVM HMC is ready. Please login once to https://10.145.14.33 and change your password. username: $username . password: $password

After that though I changed the accounts to use LDAP authentication so the password specified is not necessary. I also needed to enable the remote web access checkbox in user properties.

gschlotter will provide an FQDN. Two machines are included haldir and legolas but authentication is not accepted so far.

I asked in https://suse.slack.com/archives/C02CANHLANP/p1693985622275479

(Oliver Kurz) who knows HMC credentials for haldir or legolas and can try to establish the HMC connection details in the new LSG-QE PRG2 HMC https://10.145.14.33 ?

This topic was brought up again in weekly QE sync due to the long job schedule and many jobs scheduled for PowerVM which could not be executed for multiple weeks now.

I wrote in https://suse.slack.com/archives/C04MDKHQE20/p1694589332264709 #dct-migration

@here second wave PowerPC machines moved to PRG have been shut down 2023-08-23 and are not usable since then. My expectation for a migration period was days, it's becoming weeks if not months now. Can we clarify the expectations and priorizations here?

and referenced that in https://suse.slack.com/archives/C02CANHLANP/p1694589512949609 #eng-testing

@here As mentioned in the weekly QE sync call: The openQA job schedule for PowerVM tests is still long and can not be worked on due to all related ressources in migration to the PRG2 datacenter. I would have expected related ressources to be provided sooner which did not happen so I brought up the topic to clarify in #dct-migration https://suse.slack.com/archives/C04MDKHQE20/p1694589332264709

Apparently the expectation is that we fully administrate the HMC including the network which will prove tricky as we don't have access to some components of the network.
But regardless in the HMC in Console Management -> Console Settings -> Change Network Settings -> LAN Adapters I found that the HMC is running a DHCP server on eth1, range 10.255.255.2 - 10.255.255.254. I ran a discovery to lookup machines but after 1m that finished and showed no machines "No systems have been found in the range of IP addresses specified.".

Michal Suchanek noted:

Does not sound like a great choice given our internal network also uses these addresses. It can pose some routing challenges when trying to reach the managed machines

Regardless of the HMC I wrote in https://suse.slack.com/archives/C04MDKHQE20/p1695112259111409?thread_ts=1694589332.264709&cid=C04MDKHQE20

(Oliver Kurz) @John Ford @Moroni Flores ok, regardless of the HMC setup what are plans regarding DHCP/DNS for the PowerPC systems if any? As racktables are mostly missing MAC addresses and have no updated IP address entries and as I don't have access to the switches even I don't think it is feasible to expect from us to set this up as well.

Worked on this with nicksinger. Over the HMC one can connect to the ASM with the HMC acting as kind of a jump host. To do that we clicked in the HMC web interface on the system, then "System Actions -> Operations -> Launch Advanced System Management" and used our awesome social engineering skills to authenticate in the ASM. In the ASM "Login Profile -> Change Password" and change the password for user "HMC", e.g. to password "admin". And then in the HMC "System Actions -> Operations -> Update System Password"

And wrote in https://suse.slack.com/archives/C04MDKHQE20/p1695125093587689?thread_ts=1694589332.264709&cid=C04MDKHQE20

(Oliver Kurz) Can somebody please power on huckleberry, soapberry, blackcurrant, redcurrant, cloudberry so that we can try to connect them in the HMC?

I am able to access HMC webUI and SSH https://10.145.14.33/ by LDAP account, successfully power on legolas and its partition PARID=2.
Previously, the first port 98:be:94:07:3f:c4 can get IP address from DHCP and be used for PXE boot.
Now I set all ports as dhcp, eth2 and eth3 are up but unable to get IP address automatically.

@dawei_pang please create separate tickets for all issues concerning machines after you can already reach them like the above issue.

Thanks Oliver, I created a new ticket for the issue: https://progress.opensuse.org/issues/136124

We can track the package shipping to PRG2 DC in

Said ticket is (still) blocking on https://jira.suse.com/browse/ENGINFRA-2009 which was updated on 2023-10-16

Created https://jira.suse.com/browse/ENGINFRA-3206 "Provide PDU administrative access to LSG QE Tools for PDU-A-J11 in rack J11" as discussed in weekly DCT migration call to help Eng-Infra to help ourselves

Meeting with jford, mflores, cbachman, gsouza. Meeting minutes to be provided by jford (TBC). As followup from https://suse.slack.com/archives/C04MDKHQE20/p1699451342346359

(Oliver Kurz) @John Ford @Moroni Flores @Conrad Bachman based on the meeting we just had about pending tasks for PowerPC setup (CC @Matthias Griessmeier @Dawei Pang @Alvaro Carvajal) as we talked about freeing rackspace in J11 and related to https://jira.suse.com/browse/ENGINFRA-2908 given that there is still the hardware "H03-ch1" in https://racktables.nue.suse.com/index.php?page=object&object_id=23373 which is currently unused I don't expect new hardware in this rack planned for the next months. Maybe the easiest would be to leave all machines where they are currently mounted but only if you are able to provide a "QE (not-openQA)" network in PRG2-J11. Otherwise I would suggest to move haldir and legolas. Can you state if the QE network can be provided to selected machines in J11 plus connection to a separate QE PowerVM HMC?
(Moroni Flores) we can provide the QE network to those machines, and a separate HMC - but let me reiterate here that the arch network will not be available in this rack
(Oliver Kurz) Understood. So far I know of no requirement for arch network. Given that I suggest we keep all already racked machines in place.

I reviewed all entries in https://racktables.nue.suse.com/index.php?page=rack&rack_id=21278 and have put a proper "common name" and FQDN to separate openQA and QE (non-openQA) machines.

(Oliver Kurz) @Petr Cervinka any news regarding https://suse.slack.com/archives/C02CANHLANP/p1699017470325589 ?
(Petr Cervinka) We had call this week people and we found out that it is more broken than it looks and we need to find time for more troubleshooting later this week.

Besides that there is no further work planned by me right now.
