[ Upstream commit 2ce9a36452 ]
Whenever an I/O for a RAID volume fails with IOCStatus
MPI2_IOCSTATUS_SCSI_IOC_TERMINATED and SCSIStatus equal to
(MPI2_SCSI_STATE_TERMINATED | MPI2_SCSI_STATE_NO_SCSI_STATUS) then
return the I/O to SCSI midlayer with "DID_RESET" (i.e. retry the IO
infinite times) set in the host byte.
Previously, the driver was completing the I/O with "DID_SOFT_ERROR"
which causes the I/O to be quickly retried. However, firmware needed
more time and hence I/Os were failing.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
