VM处于挂起状态、无法从VMware端从其专用主机进行访问
适用场景
- ONTAP 9
- ESXi 主机
- SAN (FC)
问题描述
- 无法访问VM 、并且 主机端出现IO错误
- 链接重置事件、即 scsitarget_hwpfct_errorReset 以及 同一主机SID导致FCP SRAM转储和IO wqe失败、并显示Ext_Status 0x16 存储端的目标端口上记录的扩展状态为16的IO wqe错误。
- 扩展状态16表示主机启动程序已发送中止以清除当前命令队列。

- 存储上的SFP功率低于建议值 目标端口上的SFP Tx和Rx功率处于建议范围内。
- 信用损失恢复是由于完全缺少Tx B2B信用。它有两个主要原因：
- 相邻设备严重拥塞。需要调查终端设备。
- 物理链路问题导致B2B信用值和帧损坏/丢失。
- 存在链路错误的问题、需要检查和/或更换两端的所有物理组件(SFP、缆线、配线板等)、以便进一步隔离问题描述。
