HDLM命令dlnkmgr详解之四_monitor/offline/online
1. monitor
以一定的时间间隔监控hba或cha口的IO信息。
命令格式
监控hba口的IO信息：
dlnkmgr monitor -hbaid HBA_ID [-intvl Interval-Time] [-count Number-Of-Times] [-t] 监控cha口的IO信息：
dlnkmgr monitor -chaid CHA_ID [-intvl Interval-Time] [-count Number-Of-Times] [-t] Valid value
HBA_ID { 00000 - 99999 }(Decimal)
CHA_ID { 00000 - 99999 }(Decimal)
Interval-Time { 1 - 60 }(Seconds) (Default Value 3)
Number-Of-Times { 1 - 999 }(Times) (Default Value 10)
命令输出说明表
| Item | Description |
| HbaID | HBA port ID |
| Port.Bus | host port number.bus number |
| Physical Device | The names of the physical device files under the /devices directory |
| StartTime | Date and time in which the command began executing |

2. offline/online
将online状态的路径设置为offline状态/将offline状态的路径设置为online状态，可以指定hba口，cha口或单条路径
命令格式
指定HBA口:
dlnkmgr offline/online [-path] { -hba HBAPortNumber.BusNumber | -hbaid HBA_ID } [-s] 指定CHA口:
dlnkmgr offline/online [-path] { -cha -pathid AutoPATH_ID | -chaid CHA_ID } [-s] 指定路径:
dlnkmgr offline/online [-path] -pathid AutoPATH_ID [-s] 指定设备名:
dlnkmgr offline/online [-path] -device SCSI_Device_Name [-s] Valid value
AutoPATH_ID { 000000 - 999999 }(Decimal)
HBA_ID { 00000 - 99999 }(Decimal)
CHA_ID { 00000 - 99999 }(Decimal)
