family driver 34.Sh SYNOPSIS 35To compile this driver into the kernel, 36place the following lines in your 37kernel configuration file: 38.Bd -ragged -offset indent 39.Cd "device pci" 40.Cd "device scbus" 41.Cd "device da" 42.Cd "device mly" 43.Ed 44.Pp 45Alternatively, to load the driver as a 46module at boot time, place the following line in 47.Xr loader.conf 5 : 48.Bd -literal -offset indent 49mly_load="YES" 50.Ed 51.Sh DESCRIPTION 52The 53.Nm 54driver provides support for Mylex AcceleRAID and eXtremeRAID-family 55PCI to SCSI RAID controllers with version 6.00 and later 56firmware. 57.Pp 58Logical devices (array drives) attached to the controller are presented 59to the SCSI subsystem as though they were direct-access devices on a 60virtual SCSI bus. 61Physical devices which are not claimed by a logical 62device are presented on SCSI channels which match the physical channels 63on the controller. 64.Sh HARDWARE 65Controllers supported by the 66.Nm 67driver include: 68.Pp 69.Bl -bullet -compact 70.It 71Mylex AcceleRAID 160 72.It 73Mylex AcceleRAID 170 74.It 75Mylex AcceleRAID 352 76.It 77Mylex eXtremeRAID 2000 78.It 79Mylex eXtremeRAID 3000 80.El 81.Pp 82Compatible Mylex

initialisation complete" 89.Pp 90The controller firmware has started initialisation. 91Normally this process is performed by the controller BIOS, 92but the driver may need 93to do this in cases where the BIOS has failed, or is not compatible 94(e.g.\& on non-x86 systems). 95.It "mly%d: drive spinup in progress" 96.Pp 97Drive startup is in progress; this may take several minutes. 98.It "mly%d: mirror race recovery failed, one or more drives offline" 99.It "mly%d: mirror race recovery in progress" 100.It "mly%d: mirror race recovery on a critical drive" 101.Pp 102These error codes are undocumented. 103.It "mly%d: FATAL MEMORY PARITY ERROR" 104.Pp 105Firmware detected a fatal memory error; the driver will not attempt to 106attach to this controller. 107.It "mly%d: unknown initialisation code %x" 108.Pp 109An unknown error occurred during initialisation; it will be ignored. 110.El 111.Ss Driver initialisation/shutdown phase 112.Bl -diag 113.It "mly%d: can't enable busmaster feature" 114.It "mly%d: memory window not available" 115.It "mly%d: can't allocate register window" 116.It "mly%d: can't allocate interrupt" 117.It "mly%d: can't set up interrupt" 118.Pp 119The system's PCI BIOS has not correctly configured the controller's 120PCI interface; initialisation has failed and the driver will not 121attach to this controller. 122.It "mly%d: can't allocate parent DMA tag" 123.It "mly%d: can't allocate buffer DMA tag" 124.It "mly%d: can't allocate command packet DMA tag" 125.It "mly%d: can't allocate scatter/gather DMA tag" 126.It "mly%d: can't allocate s/g table" 127.It "mly%d: can't allocate memory mailbox DMA tag" 128.It "mly%d: can't allocate memory mailbox" 129.Pp 130A resource allocation error occurred while initialising the driver; 131initialisation has failed and the driver will not attach to this 132controller. 133.It "mly%d: BTL rescan result corrupted" 134.Pp 135The results of a scan for an attached device were corrupted. 136One or more devices may not be correctly reported. 137.It "mly%d: flushing cache..." 138.Pp 139The controller cache is being flushed prior to detach or shutdown. 140.El 141.Ss Operational
