问题解答

当主机适配器因受到 I/O 请求的影响或由于 HA 超时而中止 I/O 请求时,会出现此消息。

示例错误:

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

这种情况并不一定意味着目标设备有问题。高工作负载会导致环路饱和、导致总线的设备争用。传输问题也会导致环路吞吐量降低、从而导致 I/O 所需时间比正常时间长。偶尔会看到,不需要执行任何操作;系统会通过重试已中止的 I/O 来自动处理该条件。与持续的错误情况(例如设备重置或传输错误)关联时,很可能是环路稳定性问题的症状。
