This RAS ticket is usually generated when data in the blockpool is tagged as un-trusted. Sudden power losses to the DXI v1000 can cause this.
There is a method to fix the blockpool which involves running a reference verify job which takes the DXi offline while it runs and then running additional verify jobs to ensure no corruption is in the blockpool (these verify jobs run while the DXi is still online). All of the verify jobs are initiated via the cli using the root user account so in case like these a support contract is needed to resolve the issue.
The DXi will still be available for backups but you may run into an issue with corrupted data when you try to run a restore job.
