Datastore Capacity 0 after iscsi error - what to do?

Question

FreeBSD

Good afternoon. We have a storage system on FreeNas 11.6, to which a 14 TB partition is connected (hardware RAID 6) ZVOLs of 13.5 TB and 500 GB are created.

The storage system is connected to 2 VmWare 6.7 hosts via iscsi 10 Gb / s.

After errors:
cpu14:2099880 opID=dfaa4e7e)WARNING: ScsiDeviceIO: 8385: SITPUA set to 0 for device naa.6589cfc0000006fae8a5f330df7f7f34. This may cause log spam. The system was unable to change this setting to 1. Failure

follows.




The question is how to return Datastors to their previous form, or at least get data from zvol'ov in the form of folders with virtual machines.

Thanks for the advice.
