Hi All,
Fixed. After HPE RC analysis, she identify disk enclosure 14 failed. Although it may show
Disk Enclosure 10 P1(failed) -> Disk Enclosure 14 P2 & Disk Enclosure 14 P1 -> Disk Enclosure 12 P2(failed).
But the fact is Disk Enclosure 14 cause D.E. P1 and D.E. P2 lost connection.
Anyway, only HPE RC can find this by running a analysis report.
