Shadowing problem

[debu_17]

I feel that the errors due "Data Check on write" may have something to do with , the write cache for this disk, as the cache may be shared with the main disk for which dsa100 is the shadow volume.
2. as already suggested the async operations
may modify the data before the write check completes.

Your answers helped me understanding what is happening on the system. I now have an idea why this error occurs and why it doesn't happen very often.

Thank you very much.

I turned DATA_CHECK off.

I hope this will solve the problem, but as this is not seen very often, it will take some months maybe years until we can be quite sure.

Curious - to seeing this problem were there any kits installed - you can send the PRODUCT SHOW HISTORY to john.hockett@hp.com

Thanks
