Mixing Drive Types on the HBA Might Cause Slow Repair of
a Degraded Logical Drive
Bug ID: 26220425
Issue:
When mixing both solid state drives (SSDs) and hard disk drives (HDDs) on the HBA, global
hot spares are used to repair degraded logical drives, regardless of the drive type (SSD or
HDD). This behavior occurs due to the importance of fixing a degraded logical drive over
preserving performance-related rules on drive mixing. Therefore, if the only global hot spare
available is a different drive type from a degraded logical drive, it might result in using a slower
drive to repair that degraded logical drive.
Workaround:
Use dedicated hot spares tied to logical drives that match the drive type: SSD or HDD
