Installation guide

All Architectures

• The irq handler is now freed when __tw_shutdown() is initiated. This prevents a possible null

pointer de-reference if an interrupt was shared during shutdown.

• RCD bit for caching mode page is now turned on.

• ioctl resets and scsi resets are now serialized so they no longer collide.

• 3w-9xxx: driver for 3ware SATA RAID Controllers updated to version 2.26.08. This applies several

upstream changes, most notably:

• The pci_unmap_single() call now functions correctly on systems with greater than 4GB of

RAM

• Fixed a bug that caused slow write performance.

• The DMA mask setting now reverts to 32-bit if 64-bit fails.

• Added support for the 3ware 9690SA SAS Controller Device.

• megaraid_sas: driver updated to version 4.01-rh1. Several bug fixes are applied by this update,

including:

• MFI_POLL_TIMEOUT_SECS is now 60 seconds.

• Fixed a bug that caused continuous chip resets and command timeouts due to frame count

calculation.

• Added support for the LSI Generation 2 Controllers (0078, 0079).

• Added a command to shutdown DCMD in the shutdown routine to improve firmware shutdown.

• Fixed a bug that caused unexpected interrupts in the hardware Linux driver.

• the qla2xxx driver for QLogic Fibre Channel Host Bus Adapters has been updated, adding support

for ISP84XX type cards.

• the ibmvscsi drivers for emulating virtual SCSI (vSCSI) devices has been updated, providing

support for virtualized tape devices.

• lpfc: driver updated to version 8.2.0.30. This update applies several bug fixes and enhancements,

including:

• Improved Enhanced Error Handling (EEH) for PCI adapters on PowerPC architectures

• Increased the number of supported NPIV virtual ports

• Improved driver logic to control I/O queue depth

• Added support for Fibre Channel over Ethernet (FCoE) adapters

• Booting from SAN for new hardware is now supported

• the cciss driver for HP Smart Array controllers has been updated to version 3.6.20-RH2.
