适用于

  • Ontap
  • iscsi
  • ESXi

问题

  • ESXi 主机在网络交换机维护活动期间丢失了活动的 iscsi 会话
  • ESXi 主机报告所有路径关闭(APD)
  • 在一台交换机上执行活动,而另一台交换机保持在线
  • igroup show -v 在问题时间戳期间显示 iqn 状态为 not logged in
  • 我们可以看到 san 启动器登录在问题时间戳期间缺少通知,这意味着 iqn not logged in 到任何 lifs

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 lifs(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重新建立会话
