(Resending in plain text as the earlier email got bounced) Hi All, We have prepared driver patch from latest driver source. We worked on a issue related to SMARTCTL([Bugme-new] [Bug 15623] New: doesn't allow SMART-passthrough on Adaptec Series 5 controller) and found the root cause of this problem. We have responded to this bug, stating that we will be releasing the driver patch for addressing this problem. Also, in our recent program releases we have addressed some more issues. Please look into the release notes. Please find the attachments. 1. aacraid-version-26400-040510-patch - Driver patch 2. aacraid-scsi-misc-2.6-warnings.txt - Warning message text 3. Release notes Thanks & Regards, Mahesh Linux Driver Development Engineer, Adaptec ODC, Bangalore

AACRAID Driver for Linux - version 26400 ---------------------------------------- Addressed issues: ---------------- 1. The default driver setting is "expose_physicals=0", which means raw physical drives not exposed to OS. If the user wants to expose connected physical drives, enable "expose_physicals" module parameter. With the new JBOD firmware, physical drives are not available for "expose_physicals>0". In function "aac_expose_phy_device", added to reset the appropriate bit in the first byte of inquiry data. This fix exposes the connected physical drives. 2. Added support for handling ATA pass-through commands. When the "CC" bit is set by the host in ATA pass-through CDB, driver is supposed to return DID_OK When the "CC" bit is reset by the host, driver should return DID_ERROR 3. Firmware exposes lesser container capacity than the actual one. It exposes [actaul size - hidden reserved space(10MB)] to the OS, IO's to the 10MB should be prohibhited from the Linux driver. When the IO's falls into hidden reserved space, driver internally sets sensekey to HARDWARE_ERROR and sends notification to the SCSI mid layer. Added "expose_hidden_space" flag, by default the fix will be executed. Only if the user sets "expose_hidden_space=1", user can access beyond the array reported size(hidden reserved space 10MB). 4. Based on the notification from firmware, the driver sets up SDV_OFFLINE flag for a deleted array and the SCSI mid layer comes to know the attached SCSI device has gone offline. But with this notification, scsi device entries are not being removed. Enabled "AAC_DEBUG_INSTRUMENT_AIF_DELETE" flag in the header file, with this flag the driver uses "scsi_remove_device". On the notification from firmware, the driver calls "scsi_remove_device" for the deleted array. This call not only informs the scsi device status to the SCSI mid layer but also removes corresponding scsi device entry from the linux sysfs.
