Certain HPE SAS SSDs may randomly go offline and disappear when running in the Operating System (OS) without any error showing on the HPE Active Health System (AHS) logs. The SSDs become unresponsive because of the SAS Low Priority Commands (LPC).To verify if this is the issue, check the OS or Smart Array Controller logs that will show multiple low-priority command timeouts before the SSDs disappeared from the OS logs.VMware OS Log Example:2024-04-16T09:46:30.838Z Wa(180) vmkwarning: cpu98:3041235 opID=a4f71ddc)WARNING: ScsiDeviceIO: 6666: Failed to issue command (0x25) on device naa.5000039cb81abb5d: Timeout2024-04-16T09:46:30.838Z Wa(180) vmkwarning: cpu98:3041235 opID=a4f71ddc)WARNING: ScsiDeviceIO: 6837: Couldn't issue sync command (opcode 25) on device 'naa.5000039cb81abb5d': Timeout2024-04-16T09:46:30.838Z In(182) vmkernel: cpu98:3041235 opID=a4f71ddc)ScsiDeviceIO: 6421: Command 0x1a (CmdSN 0x160234b, World 0) to device naa.5000039cb81abb5d timed out: expiry time occurs 0ms in the past2024-04-16T09:46:30.838Z Wa(180) vmkwarning: cpu98:3041235 opID=a4f71ddc)WARNING: ScsiDeviceIO: 6666: Failed to issue command (0x1a) on device naa.5000039cb81abb5d: Timeout2024-04-16T09:46:30.838Z Wa(180) vmkwarning: cpu98:3041235 opID=a4f71ddc)WARNING: ScsiDeviceIO: 6837: Couldn't issue sync command (opcode 1a) on device 'naa.5000039cb81abb5d': Timeout2024-04-16T09:46:30.838Z Wa(180) vmkwarning: cpu98:3041235 opID=a4f71ddc)WARNING: ScsiDeviceIO: 12986: READ CAPACITY on device "naa.5000039cb81abb5d" from Plugin "HPP" failed.
