R5300 G6 reports SATA All-in-one cable connection error

The drive configuration is a 12LFF backplane (0302A6VS), with the P460 card connected to two F0/F1 SATA SSDs, and F8-F11 being four NVMe drives.

Customer reported batch repair for about 10 R5300 G6 servers with drive All-in-one cable alarm in SEL: Configuration Error-Incorrect cable connected / Incorrect interconnection---Incorrect SATA cable connection to the system board. No actual usage issues found.

1. The customer provided logs from two devices, revealing an Incorrect SATA cable connection alarm after upgrading the HDM version around 9:40 on November 15. Suspected to be a false positive.

2. The CPLD version is V005, and the faulty version is V004; the Release Notes for V005 indicate that this issue has been resolved. Trigger condition: the error occurs only with specific machine configurations. In V004, there is a probabilistic false positive in the logic loop detection, and the All-in-one cable alarm detection log is reported only once when the BMC starts up and not repeated afterward. After an on-site BMC upgrade, the HDM reboots, at which point the alarm is triggered.

Upgrade CPLD version to V005 or above.
