Symptoms
根据戴尔最佳实践，尝试将 IOPS 值调整为 1而不是 1000（默认值）时收到错误。
错误消息（适用于 ESXi 5.x/6.x）：
#esxcli storage nmp psp roundrobin deviceconfig get --device=naa.<wwn> Byte Limit: 10485760 Device: naa.<wwn> IO Operation Limit: 1000 Limit Type: Default Use Active Unoptimized Paths: false #esxcli storage nmp psp roundrobin deviceconfig set --device=naa.<wwn> --iops=1 --type iops error: device naa.<wwn> unknown.
Cause
N/A
Resolution
解决方法：
尝试使用相同的命令，但使用不同的语法：
#esxcli storage nmp psp roundrobin deviceconfig set type=iops iops 1 device naa.<wwn>
这正确执行（没有输出）
设备“naa.<wwn>“现已设置为轮循，IOPS=1，如建议：
#esxcli storage nmp psp roundrobin deviceconfig get --device=naa.<wwn> Byte Limit: 10485760 <wwn> IO Operation Limit: 1 Limit Type: Iops Use Active Unoptimized Paths: false
