Re: [Xen-users] flooding kernel.log

[Abdallah Jabbour <it-j@xxxxxxxxx>]

IET support older scsi2 protocol , I had this issue on ESXi 5 which is not 
compatible with scsi2 and IET , only solution , if you have OpenFiler is to 
purchase the advanced iscsi target plugin , which support scsi3 and persistent 
reservation  , or switch to Linux LIO target which supports scsi3 and 
persistent reservation .

Do you experience disconnection between the storage and the hosts ? if you have 
heavy loads on the storage then you are going see some disconnections .
