KB ID 0001525 Problem I’ve got a client that’s been having some performance issues with their VMs. Their storage vendor, (EMC) said that as a result of finding this in the logs; B 02/28/19 09:50:53.953 scsitarg 117000e [INFO] System: iSCSI Logout Initiator Data: IP=192.168.200.161 Name=…-ec-21 Target Data: Port=2 Flags=0x00002002 Info=0x01200801 B 02/28/19 09:50:53.969 scsitarg 117000e...

Strangely when I selected the SAS storage controllers they could see all 5 storage LUNs,...
