Version 1.20.01 - Moderate Impact/Low Probability of Occurrence
---------------
Contains:
  BIOS          Firmware         UEFI Driver
  07.39.00.00   20.00.02.00      07.27.04.00

Enhancements:
- Added System X agentless support
- Indicate support for the ATA Device Server Password security protocol
- Allow UEFI and BIOS to be Enabled/Disabled individually
- Added ConnectorName and EnclosureLevel fields to SAS Device Page 0 to
  help identify physical location of a target device
- Set SATA HOLD threshold to be configurable in NVDATA
- If HW can gets into a stuck state, clear that state upon break received.

Fixes:
- Set SAS drives to track bad blocks using a bad block table rather than
  using a SCSI Write Long.
- Fixed DMAGroup performance issue.
- Fixed issue with Phase 18 IR FW boot a RAID volume (such as raid 10),
  2308 bootup hangs at OROM "Initializing.." and fault 8803 seen.
- Fixed report Luns command to a SATA drive fails with
  CheckCondition/Invalid Field in CDB when Allocation length set to Zero.
- Fixed issue where Raid Accelerator IOs can hang if the stream of IOs
  suddenly stops.
- Fixed issue where an invalid frame sent during a PIO-mode SATA
  passthrough command results in resetting the drive.
- Fixed issue where lots of NCQ I/O error messages were reported.
- Fixed issue where certain PCIe timeouts occur in the presence of link
  unavailable, and a hang condition or data corruption can occur.
- Fixed issue where system hangs after adapter reset with heavy IO load.
- Fixed issue where access to Last Logical Block Address (LBA) of SATA
  Drive is Prevented and LBA out Of range by one block is missed.
- Made change to deal with link getting stuck and causing missing drives.
- Fixed IR issue where page header information is not filled in when RAID
  PHYS DISK PAGE 0 is returned for a non-RAID Disk drive.
- Fixed issue where controller hits 0x265d fault while creating volume
  when there is an inactive volume.
- DID_SOFT_ERRORs are seen when hot plug is performed on the RAID1 volume
  along with IOs.
- Fixed issue where system gets hung and reboots while running IO's along
  with diag reset on the Controller which has active and inactive volumes.
- Fixed latency spikes seen during performance testing on OEM system
- MPI 2.5: distribute target command buffers received across multiple
  reply queues.
- Fixed issue where command sas2flash -dflash results in a non-functional
  system.
- Fixed issue where internal device reset storm after controller reset
  using long CDB.
- Fixed 0x6003 Fault Due to Task Management of Lost IO
- Fixed 0x58A1 fault occurs on partner controller while issuing MUR to a
  target mode controller with outstanding IOs.
- Fixed issue where IO error and stop when hot plug a HDD from RAID1
- Fixed issue where fault 8901 is seen once the volume is roamed.
