Symptoms

尝试从主元数据管理器 （MDM） 运行命令时，ScaleIO 命令失败并显示无效会话：

# scli --mdm_ip  --login --username admin
Enter password:
Logged in. User role is Administrator. System ID is XXXXXXXXX

# scli --mdm_ip  --query_all_volumes
Error: MDM failed command. Status: Invalid session. Please login and try again.

Cause

导致 MDM 拒绝连接的问题是 CallHome 用户“Monitor”每十分钟再次登录一次，并且未注销。这会导致用户登录会话累积并填满会话表，然后硬超时才会踢出它们。

Resolution

删除（或注释）以下两行： mdm/cfg/conf.txt，在两个 MDM 上：

user_session_hard_timeout_secs=86400 

user_session_timeout_secs=28800 Stop CallHome service temporarily

 

/opt/emc/scaleio/callhome/bin/delete_service.sh

重新启动 MDM 服务：

kill

等待 10 分钟，然后尝试发出 scli 命令，然后再次启动 call-home 服务。

./opt/emc/scaleio/callhome/bin/create_service.sh

Additional Information

如果 ScaleIO CLI 会话超时，也会出现此错误。
