Fixing reset to device error when running the LSI_SAS controller
- Troubleshooting
- September 30, 2019
Symptoms
When running the LSI_SAS controller in the VM, the Windows event log reports the error:
Event 129, Reset to device, \Device\RaidPort0, was issued.
In most cases, there are no logged events in Linux, except for random storage delays under high workload.
Resolution
1. Check that all StarWind devices have the Synchronized status on all nodes;
2. Check that each Datastore on each host has active paths from all StarWind nodes;
3. In VM settings check the number of SCSI adapters and number of disks assigned to VM. Note the numbers of adapters and disks;
4. Shutdown StarWind VM;
5. Remove StarWind VM from inventory;
6. Locate and make a backup of VMX file of the StarWind VM;
7. Edit and save VMX file of the StarWind VM by adding the following lines:
scsi0.async = “FALSE”
scsi0:0.canBlock = “TRUE”
scsi0:1.canBlock = “TRUE”
NOTE: Line 1 shall be introduced for every SCSI controller VM has got (0, 1, or any number it might have). Line 2 shall be introduced for every port on that controller (here is why the 3rd line is used – just for example purposes in case of two disks attached to the VM using 1 SCSI controller).
In this example, VM got one SCSI adapter and two disks assigned to it.
8. Register VM back and start one;
9. Do the same steps with another VM.
