Answer

This message occurs when the host adapter aborts an I/O request, either because it was a victim or because of an HA timeout.

Example error:

1/29/2020 14:14:54  ClusterA_01   ERROR         scsi.cmd.abortedByHost: Disk device Switch_A_1:8.126L1002: Command aborted by host adapter: HA status 0x4: cdb 0x8a:00000001564c9200:00000200

This condition does not necessarily mean that the target device is problematic. High workloads can cause loop saturation, leading to device contention for the bus. Transport issues can also cause loop throughput to decrease, thereby causing I/Os to take longer than normal. Seen occasionally, no action is required; the system handles the condition automatically by retrying the I/O that was aborted. Seen in association with a persistent error condition, such as device resets or transport errors, it is likely the symptom of a loop stability problem.
