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
