Original Document Release
Replacing the SAS Expander HBA (Spare P/N: 761879-001) with a newer SAS Expander HBA (Spare P/N: 876907-001) results in a System Alert and recommends downgrading the firmware.
This issue only occurs only when the existing SAS expander is replaced. The new SAS expander HBA (P/N: 876907-001), which replaces 761879-001, does not support a downgrade of its firmware. Downgrading the firmware leads to the SAS expander HBA being unusable and can result in a potential data unavailability scenario.
