OEM Name : MRaid2k.sys
Engineering Release date : 01/06/2004
Previous Version Release : 5.44
New Version # : 5.46

Reason for Release (including Bug Fixes and Enhancements and Feature added)
Bugs Fixed:

1. DFCT97402 - During heavy I/O in the cluster environment Driver used to stall the cpu for 3 min in a tigh loop when it received the reset command from the OS. Due to this system used to freeze and cluster failover did not happen. As a fix instead of the tight loop in the reset path driver added a timer routine which will periodically invoked and it will calculate the actual system time elapsed from the start of the issuing of reset and if it is more than 3 min it will make the adapter dead as previously.

2. DFCT96747 - If a logical drive is failed, driver did not exposed it to the OS and this results in a mismatch in the logical drive mapping between OS and RAID Management utilities. This driver will expose the failed logical drive to the OS but complete the failed IO request to with proper status information. This will fix the mismatch issue.
Enhancements:
1) Support for MegaRAID SCSI 320-1E and 320-2E controller added.

=========================================================================================

OEM Name : MRaid2k.sys
Engineering Release date : 09/09/2003
Previous Version Release : 5.43
New Version # : 5.44

Reason for Release (including Bug Fixes and Enhancements and Feature added)
Bugs Fixed:
1) Driver is returning the Bus interrupt level in the PCI information structure for use in the RAID utlities.
Enhancements:
1) The TimeOut Value in the Registry entry under Disk.sys has been increased to 60 secs from 40 secs to prevent Event ID 9.
2) Support for MegaRAID SCSI 320-0X support added to the registry.
3) Support added for the SATA(523) SAF-TE device from AMI.

EARILER RELEASE NOTES
---------------------------------------------------------------------

OEM Name : MRaid2k.sys
Engineering Release date : 04/22/2003
Previous Version Release : 5.40
New Version # : 5.41

Reason for Release (including Bug Fixes and Enhancements and Feature added)
Bugs Fixed:
1) 471/493 controllers used to have DEC bridge. On some of the new 471/493 controllers we have started using PeriCom PCI Bridge.So the support has been added in the driver for the scanning of the new PeriCom PCI Bridge.
2) For 531 controllers, during the system goes into hibernation, the system used to hang as the Chips were running into D3 state. A check has been put in the driver where the driver would check the state of the Chip. If the chip is in D3 state, the driver would skip the scanning of that Bus Number.

3) During back to back Write Config, Firmware used to go hang. This was due to the fact that the driver was using the same commandID for the Multiple Write Config. A fix has been made in the driver where the driver would be using individual commandID for each WriteConfig issued to the Firmware.

4) GAM utility fix. Driver was not updating some of its internal structures whenever GAM used to send a WriteConfig/ReadConfig call to the driver. A fix has been put in the driver where the driver is updating its internal mailbox structure with all the information send by the GAM utlility.

5) Firmware was not able to handle multiple Reserve commands for a logical drive. This was leading to the Reservation failures on some of the logical drives. A fix has been done in the driver where in the driver would accept only one Reservation call at a time and would allow it to complete before issuing any more commands to the Firmware.

6) AdapterFlush issue. From the PC++, we can flush the Adapter cache and also after shutdown, we flush the adpater cache for every
Read and Write coming after the shutdown. This was hurting the performance as if we run I/O after flushing the adapter cache from the
PC++, driver used to flush the cache for every Write going to the logical Disk. In order to differentiate between the 2 adapterFlush, we check for
the additonal information in the IOCTL command send by PC++.

Enhancements:
1)Support for LSI 320-2X and LSI 320-4X scsi processor devices added to the nodev.inf file.

Observations

1. OEM Name: LSI

2. Product Name: MegaRAID Windows NT 4.0 Driver (Mraid35x.sys)

3. Release Date: 10/04/2002

4. New Version Release: 4.10

5. Previous Version Release: 4.09
Version: 4.10
=============

Bug Fix:
-------
1. Utilities are issuing 0xc3 calls for getting the logical drive statistics.
We have seen some utilities are requesting 40LD statistics but send buffer
less than 40LD statistics size. This is causing the system to crash.
This bug has been fixed in the driver by returning all the calls with less
buffer size (< 40LD statistics size) without copying any data successfully.
Version: 4.09
=============

Enhancements:
-------------
1. Support added for 520 and 518 controllers.


Known Restrictions/Bugs:

1. Performance will degrade if NT service pack 5 or higher is not installed.
Installation Procedure:
----------------------
1. To install the MegaRAID driver during installation of NT from floppy diskettes, select S at the
appropriate time to select the MegaRAID driver on diskette.
2. If installing NT from a bootable CD (IDE or non-MegaRAID SCSI), press the F6 key when the following
message is displayed:

"Setup is inspecting your computers' hardware configuration."
Then select S at the appropriate time and select the MegaRAID driver on diskette.
Driver Installation Upgrade:
----------------------------
1. To install the MegaRAID driver on an existing NT configuration, select the SCSI Adapters in the NT
Control Panel.
2. Select the Driver tab and select the Add button.
3. Any previously installed MegaRAID Drivers should be removed prior to installing a new one. Select the
Remove button to remove the driver.

Determining the version number of the MegaRAID driver
=====================================================
To display the version number of the MegaRAID driver you are currently using, do the following:
- Bring up the Windows Explorer
- Under View-Options, make sure Show all files is selected
- Go to the \WINNT\SYSTEM32\DRIVERS folder and find either MEGARAID.SYS or MRAID35X.SYS
or EXPLORER.SYS.
- Right click on the file and select Properties.
- Select the Version tab to see the version number

If both MegaRAID.SYS and MRAID35X.SYS files are present, determine which one is currently started by doing the following:
- Go to the NT Control Panel and Select SCSI Adapters
- Highlight the MegaRAID Adapter and select Properties
- The driver name is listed under the Driver tab

Windows 2003 Name : MRaid35x.sys
New Windows 2003 Version # : 6.41.2.32

Summary of recent changes:
==========================
1. Added support for additional controllers in inf files.
2. During heavy I/O in the cluster environment, the driver used to stall the cpu for 3 min in a
tight loop when it received the reset command from the OS. Due to this system used to freeze
and cluster failover did not happen. This has been fixed.
3. If a logical drive is failed, driver did not expose it to the OS and this results in a mismatch
in the logical drive mapping between OS and RAID Management utilities. This driver will expose the
failed logical drive to the OS but complete the failed IO request to with proper status information.
This will fix the mismatch issue.
