适用场景

  • ONTAP
  • iscsi
  • ESXi

问题描述

  • ESXi主机在网络交换机维护活动期间丢失活动iSCSI会话
  • ESXi主机报告所有路径已关闭(APD)
  • 活动在一个交换机上执行、而另一个交换机保持联机
  • igroup show -v 在问题描述期间、时间戳显示iqn状态为not logged in
  • 在问题描述时间戳期间、我们可能会看到SAN启动程序登录缺失通知、这意味着iqn not logged in 指向任何一个LUN

Sun May 12 10:20:16 +0000 [stxx1-02-apxx7: bcomd: san.initiator.login.missing:notice]: Initiator "iqn.1998-01.com.vmxxre:node0xx-apxx7.xx.na-ca-1.cloud.sap:18xx9063x1:x4" is not logged in to any LIFs on this node for Vserver "stnxx1-axxx7-iscsi", portset "-". Access to LUNs might be disrupted if a failover occurs.

  • NetApp LUN (目标)不会在任何给定时间点终止或阻止连接
  • 主交换机维护活动完成后、会话将重新建立
