Axiom Brick RAID Preemptive Copy may cause storage to go offline temporarily
Preemptive Copy is a feature of the Axiom where the data contained on a disk drive within a Brick storage enclosure is proactively copied away if it is determined that the drive has degraded to a point that failure is imminent. The Axiom attempts to copy the data off the drive prior to removing it from the associated RAID array in preparation for replacement.
A vulnerability has been discovered with the Preemptive Copy feature which may affect access to storage.
Affected Hardware and Software Versions
This issue affects all Axiom systems that are on AxiomONE 4.2.0 through 4.2.10 releases. The issue was mitigated beginning 4.2.11 by removing the feature until such time it could be corrected.
