be functional.
● Verify FC HBA and all FC cables are fully seated.
● Verify all SFPs are fully seated and are known to be
functional.
Verify the SAS HBA and all SAS cables are fully seated.
The NVRAM module takes 2-3 hours to reach 80% charge. If
the NVRAM is not charged to 80% or more, the system will
generate errors and performance is degraded.
