I have a storage class lower filter driver for write protection. Most of the storage devices used in our units are connected to a LSI SAS/SATA host adapter. The filter works fine with the older lsi_sas2.sys driver. But they have changed something in the new generation lsi_sas3.sys that my filter does not catch any IRPs anymore. I have not tried to debug the driver yet, but I noticed in their release notes they are stating that the new miniport is using the STORPORT rather than SCSIPORT interface. So I am wondering if that has anything to do with my filter not working now, and if there is an easy fix.
Thanks for any input,
