MLY(4) BSD Kernel Interfaces Manual MLY(4) NAME
mly -- Mylex AcceleRAID/eXtremeRAID family driver SYNOPSIS
mly* at pci? dev ? function ? scsibus* at mly? DESCRIPTION
The mly driver provides support for Mylex AcceleRAID and eXtremeRAID family of PCI to SCSI RAID controllers with version 6.00 and later firmware. Supported controllers include: o AcceleRAID 160 o AcceleRAID 170 o AcceleRAID 352 o eXtremeRAID 2000 o eXtremeRAID 3000 Compatible Mylex controllers not listed should work, but have not been tested. Logical devices (disk arrays) attached to the controller are presented to the SCSI subsystem as though they were direct-access devices on a virtual SCSI bus. Physical devices which are not claimed by a logical device are presented on SCSI channels which match the physical chan- nels on the controller. The results of the SCSI ``INQUIRY'' command from logical devices are overwritten with status information by the mly driver. The vendor field is the string ``MYLEX'', the product field indicates the type of logical device, and the revision field contains a four letter status code. The possible status codes and their meanings are as follows: OFLN offline UNCF unconfigured ONLN online - optimal CRIT critical - one or more disks in the array has failed NORD write only STBY standby MISS missing DIAGNOSTICS
Controller initialization phase mly%d: controller initialization started mly%d: initialization complete The controller firmware has started initialization. Normally this process is performed by the controller BIOS, but the driver may need to do this in cases where the BIOS has failed, or is not compatible (e.g. on non-x86 systems). mly%d: drive spinup in progress Drive startup is in progress; this may take several minutes. mly%d: mirror race recovery failed, one or more drives offline mly%d: mirror race recovery in progress mly%d: mirror race recovery on a critical drive These error codes are undocumented. mly%d: FATAL MEMORY PARITY ERROR Firmware detected a fatal memory error; the driver will not attempt to attach to this controller. mly%d: unknown initialization code %x An unknown error occurred during initialization; it will be ignored.

The mly driver first appeared in NetBSD 1.6, and was based on the FreeBSD driver of the same name. BUGS
The mly driver currently assumes that all busses support at most 16 targets and 1 logical unit per target. Enclosures are not named or otherwise identified in event messages. The transfer speed for devices is always reported to the kernel as 20MHz. BSD
