    Kanstantsin Novice

      Hi There,

       

      VMware ESXi, 5.5.0, 3248547

      iSCSI target Linux LIO.

       

      Host is connected to iSCSI target on Linux.

      From time to time ESXi host moves to not responding state. It respond to ping but not respond to vsphere client.

       

      Syslog:

      On Linux target I see:

      TARGET_CORE[iSCSI]: Detected NON_EXISTENT_LUN Access for 0x00000024.

       

      What`s going on? Why ESXi is stop responding?

      Is anybody know?

       

      Thanks in advance.
