Hello, we are happily using 3 supermicro hosts in pool with 10G shared iscsi storage. Hosts have different configurations witch latest BIOS.
host1 - Supermicro X8DTN, Xeon X5650, areca 1680, Supermicro STG-I2 (intel 82598EB)
host2 - Supermicro X9DRH, Xeon E5-2630 areca 1222, Supermicro STG-I2 (intel 82598EB)
host3 - Supermicro X10DRi, Xeon E5-2640, areca 1226, Supermicro STG-I2 (intel 82598EB)
Last weak I upgraded pool from XS 6.2 SP1 to 7.0 with all hotfixes. After couple of hours trouble-free and fast operation, all 3 hosts starting to freeze. There is nothing on console and no crash dump. After hard reset I saw the error (attached). Only after turning on/off the server boot again.
Only mutual hardware is the 10G STG-I2 Cx4 card used to iscsi SAN connection.
With Xenserver 7.1 there is same problem.
After downgrade to Xenserver 6.2 SP1, everything works fine again.
Any advice will be appreciated.
