| LSID100125483 | (DFCT) | Unixware driver fails to load |
| LSID100125630 | (DFCT) | FW breaks into megamon while loading the driver during boot |
| LSID100125001 | (DFCT) | Timeout value not adequate to allow for spin up of physical drives |
| DFCT ID: | LSID100125483 |
| Headline: | Unixware driver fails to load |
| Description: | FW breaks into megamon after loading driver in OS. |
| Version of Bug Reported: | 5.0 |
| Version of Bug Fixed: | 4.05 |
| Steps to Reproduce: | Install OS to local drive load driver in OS Reboot, FW breaks into megamon |
| Resolution: | Fixed |
| Resolution Description: | Root cause:- Driver is interpreting 32-bit address as 64-bit address. Solution:- Adding support to segregate OS allocated address (as 32-bit or 64-bit) in IEEE SGL implementation. |
| Fix Impact: | Medium |
| Suggested Testing: | Load the driver and run some basic IO. |
| Child Tasks: | LSID100111836 |
| Duplicates: | LSID100125630 |
| DFCT ID: | LSID100125630 (DUPLICATE) |
| Headline: | FW breaks into megamon while loading the driver during boot |
| Description: | With IEEE SGL implementation FW breaks into megamon while loading the driver during SCO OS boot. |
| Version of Bug Reported: | 2.0.03-0626 |
| Steps to Reproduce: | Install SCO HBA driver Create any LD and boot into SCO OS. PS: Dont connect System PD's to controller. |
| Resolution: | Duplicate |
| Resolution Description: | Task associated with fix for LSID100125483 addresses the issue. |
| Original DFCT: | LSID100125483 |
| DFCT ID: | LSID100125001 |
| Headline: | Timeout value not adequate to allow for spin up of physical drives |
| Description: | While bringing up the FW from BIOS/EFI, pre-boot apps or driver, it is waiting for 3 minutes to allow
the MegaRAID FW to spin-up the physical drives and be ready. It has been found that 3 minutes might not be enough. So we need to reset the timer every time we detect a change in FW status. (Here FW status is 32 bit value). So any change in the 32 bit value will reset the timer and wait for 3 minutes from that point of time before killing the FW. This will allow FW enough time to spin up every drive. |
| Version of Bug Reported: | 4.04 |
| Steps to Reproduce: | None. |
| Resolution: | Fixed |
| Resolution Description: | Added code to provide sufficient time for PD spin up and monitoring FW registers for spin up progress. |
| Fix Impact: | Low |
| Suggested Testing: | 1) The driver should see MFI_STATE_DEVICE_SCAN state from the firmware and wait. This can be achieved by having an enclosure in which device spinup takes a long time. 2) Use a custom firmware which forces the firmware to be in device scan state for a couple of minutes. There should be a change in absolute value of the doorbell register( depicts drives spinning up), however the firmware state should remain devices scan only. Note: To test with debug FW one should skip BIOS while booting (use hot key ctrl+E) |

| Headline: | Segregating 32&64-bit addr in IEEE implementation |
| Description: | Adding support to segregate OS allocated address (as 32-bit or 64-bit) in IEEE SGL implementation.
Before this every address coming from OS is handled as a 64-bit address. But in case of 32-bit machine this misinterpretation is causing Driver to not load. |
