Storreclaim stopped with error 1117

Hello,

I was running storreclaim on win2k8 cluster platform. I started running it on 3 servers (each server part of separate clusters) and it failed on all of them after running for sometime. The error I got was:

[20120905 00:48:19] DeviceIoControl(IOCTL_SR_WRITE_SAME) failed with error 1117.

[20120905 00:48:19] Failed to issue reclamation IOCTL. Error 1117

With the first run I could reclaim about 100GB of space before it failed, but the subsequent runs are failing without any reclaim. 2 of the drives that I am running it on are 3TB (one 70% and another 30% allocated) and 1 drive is 2 TB (99% allocated).

Any help would be greatly appreciated.

Thanks,

Kaustuv
