Could be many things: hardware, load, connectivity. you need to investigate in more detail.  Are you sure you need to restart the iSCSI disk if you connect from other clients, it does not connect unless you restart the disk ?

Hi team,

 

I have checked in ESXI host server log showing pool issue and DAVG reaching 6,000 above please suggest for the same.

 

Note:ISCSI disk only your facing this issue

 

Please provide any technical person contact number.
