Etki

GÇ'ler etkilenmez, bu hatalar yeniden denenebilir. Yoğun G/Ç trafiği ile olası performans düşüşü

Kümedeki ESXi ana bilgisayarlardan biri yanlış yapılandırıldı: VMFS. HardwareAcceleratedLocking ayarlanmadı.

ATS kilitleme, vSphere'de dosya sistemine göre veya genel olarak etkinleştirilebilir. Bu durumda, kümedeki tüm ana bilgisayarlar tüm VMFS veri depoları için eşleşen ayarlara (yalnızca ATS) sahiptir ancak bir ana bilgisayarda bunu genel olarak devre dışı bırakmıştır:

[root@ESXI01:~] cat /etc/vmware/esx.conf |grep HardwareAcceleratedLocking
/adv/VMFS3/HardwareAcceleratedLocking = "0"

Karşılaştırma amacıyla, veri deposu başına kilitleme doğru şekilde ayarlandı (ATS):
