** Description changed: [Impact] In order to remotely power-cycle IBM z14 GA2 (or newer) or IBM LinuxONE III (or newer) machines/LPARs from within a MAAS controller, the python3-zhmcclient libraray (>= v0.29) is needed, to provide all the functions required for controlling the HMC. [Test Plan] - * setup a MAAS controller inside a LPAR - * use that controller to deploy a new Ubuntu Server instance in an additional LPAR - * use that controller to deploy a new Ubuntu Server instance inside a KVM host (inside another LPAR) - * Power-cycle the LPAR instance - * Power-cycle the KVM instance + * setup a MAAS controller inside a LPAR + * use that controller to deploy a new Ubuntu Server instance in an additional LPAR + * use that controller to deploy a new Ubuntu Server instance inside a KVM host (inside another LPAR) + * Power-cycle the LPAR instance + * Power-cycle the KVM instance Also get confirmation from the MAAS team that things are working as expected. [Where problems could occur] This library is s390x only and zhmcclient isn’t widely used yet, it has very limited exposure within the s390 environment. If we would be hit by a regression, we would not be able to power-cycle or deploy any LPAR (or KVM host inside LPAR) machine, using a Focal-based MAAS controller. This is basically also the status quo, as the current version in Focal (v0.22) does not allow for that functionality either. [Other Info] - - https://maas.io/docs/snap/3.0/ui/power-management#heading--configure-use-ibm-z + * https://maas.io/docs/snap/3.0/ui/power-management#heading--configure-use-ibm-z + * The new package dependencies are fulfilled in Focal: + - python3-requests >= 2.20.1 (focal contains 2.22.0-2ubuntu1 in main) + - python3-decorator >= 4.0.11 (focal contains 4.4.2-0ubuntu1 in main) === Original description === While working on MAAS DPM/LPAR it turned out that a newer python- zhmcclient (package zhmcclient) is needed to get certain functions work, like especially storage group support. The latest is package is v0.27 on hirsute and v0.22 on focal. v0.28 is currently the latest release, but 0.29 is coming shortly. https://github.com/zhmcclient/python-zhmcclient/issues/731 Hence an updated package (ideally to 0.29) is needed for focal (knowing that this will require a good justification: https://wiki.ubuntu.com/StableReleaseUpdates). Please notice that MAAS was the only reason why the zhmcclient package was created at all. The updated package is especially needed for focal, since focal is the recommended base distro for MAAS DPM/LPAR, hence this would require a special SRU (for this package version bump).
