Description

Motivation

We have the machines redcurrant running with pvm_hmc and grenache running with spvm. Both are more or less doing the same but being separate ressources in OSD makes both always scarce. We should switch grenache to pvm_hmc as well.

Acceptance criteria

  • AC1: Both redcurrant+grenache run pvm_hmc OSD production jobs
  • AC2: No more jobs are scheduled with spvm on OSD
  • AC3: No OSD workers remain with spvm

The way to remove Novalink

  • power on the machine, shutdown Novalink if automatically started
  • from the HMC take management with chcomgmt
  • remove the management flag on the Novalink partition
  • delete all partitions and vios
  • release management from HMC with chcomgmt
    • with the management partition gone the machine management should get unlocked
    • machine enters recovery state, should recover after a few minutes
  • once machine recovers create and install VIOS

Thank you. We should follow those steps eventually when we execute this ticket. The step "once machine recovers create and install VIOS" might be the tricky one as we encountered on redcurrant the VIOS installer can not reach all requested ressources unless the network is temporarily switched needing IT support with access to the physical network switches.

As per SD-150999 no DHCP proxy is needed but it is required that arbitrary traffic be allowed between the HMC and the target system.

While some individual protocols are well-understood it is not the case for all traffic that happens during installation.
