重新引导同一路径上的 ATTO 桥接器或后端交换机时报告的存储柜服务( SES )设备的 SCSI 命令超时和检查条件错误。

在网桥固件升级过程中重新启动后,我们会看到目标和机箱服务设备报告未就绪:

Sat Jun 20 06:55:59 MSK [cluster_01-02: isp2400_asyncd_1: scsi.cmd.selectionTimeout:error]: Processor device FC_switch_A_2:7.126L0: Adapter/target error: HA status 0x7: cdb 0x3c. Targeted device did not respond to requested I/O. I/O will be retried. 
Sat Jun 20 06:56:46 MSK [cluster_01-02: isp2400_intrd: scsi.cmd.checkCondition:error]: Enclosure services device FC_Switch_A_1:7.126L1025: Check Condition: CDB 0x3b: Sense Data SCSI:not ready -  (0x2 - 0x35 0x2 0x0)(51). 

...

在冗余路径上重试后、机壳服务设备报告请求成功仅在 3 秒后显示:

Sat Jun 20 06:56:49 MSK [cluster_01-02: isp2400_intrd: scsi.cmd.retrySuccess:debug]: Enclosure services device FC_switch_A_2:7.126L25: request successful after retry #2/#0: cdb 0x3b (2023).
