The scan wrote each disk into a file named after the identifier it reported, wwn, path or neither, and read back the groups of one such file only. Two disks that reported different identifiers therefore never competed on their driver group: a disk without a WWN was dropped as soon as another disk reported one, and when the last disk scanned reported a WWN the readback opened the WWN files alone. A direct attached boot disk that reports no WWN thus lost to a RAID volume that reports one, which is the case the driver groups exist to decide. Write every disk into the file of its driver group and keep the identifier as the sort key inside that group, ranked so that a WWN sorts ahead of a path and a path ahead of no identifier. The driver group now decides first for every disk, the identifier still decides between disks of one group, and no disk is dropped from the scan.

The xCAT sunset was only a quick eclipse
Dear xCAT Community,
The xCAT sunset has changed course. VersatusHPC has been invited to join the xCAT Consortium, and future development will move toward direct upstream contributions coordinated with the Consortium and its existing member companies.
That matters most for Enterprise Linux 10 (EL10). EL10 support is coming to xCAT, restoring a future operating-system path for sites that still rely on xCAT. This is an important change from the previous sunset guidance, where the lack of an EL10 path was one of the strongest reasons to move away from xCAT.
The xCAT Consortium continues to recommend Confluent as the long-term successor to xCAT, and that remains the Consortium position. Users planning new cluster-management deployments should evaluate Confluent and its xCAT comparison documentation.
At the same time, xCAT is no longer sunsetted. The Consortium and participating companies will continue updating xCAT while there is community and user demand for it.
In summary:
- xCAT development is continuing upstream through the Consortium and participating companies.
- Enterprise Linux 10 support is coming.
- Confluent remains the Consortium-recommended successor and migration path.
- xCAT updates will continue while there is community and user demand.
We want to thank the xCAT Consortium and community for keeping this project moving. The sun went behind the moon for a moment, but xCAT is still here.
For more information on Confluent and how to get started, please visit the Confluent: Project Page, Documentation or Confluent vs xCAT comparison.
With thanks,
The xCAT Consortium
