NAME

ips -- IBM/Adaptec ServeRAID controller driver

SYNOPSIS

device scbus device ips

DESCRIPTION

The ips driver claims to support the IBM (now Adaptec) ServeRAID series SCSI controller cards. Some supported devices include: IBM ServeRAID 3H ServeRAID 4L/4M/4H ServeRAID Series 5 ServeRAID 6i/6M ServeRAID 7t/7k/7M Newer ServeRAID controllers are supported by the aac(4) or mfi(4) driver. These cards come with a built in configuration utility stored in the firmware known as the ISPR. This utility is accessed with the CTRL + I key combination during the initial card POST. It is highly recommended that this utility be used to configure the card before attempting to diagnose the below error messages. In some cases, the ips driver can have difficulties attaching during the system initialization period. To avoid these difficulties, set the hw.ips.0.disable tunable to ``1''. This MIB prevents the driver from attaching. If you see occasional iobuf errors on the console after sync(2) or fsync(2) are issued, you can try setting debug.ips.ignore_flush_cmd tunable to ``1'' and see if that stops it. You can also use the sysctl(8) command to change this setting after boot.

DIAGNOSTICS

Several error codes may be shown when the card initializes the IBM ISPR utility and are independent of DragonFly. ips%d: failed to get adapter configuration data from device ips%d: failed to get drive configuration data from device Unable to obtain adapter or drive configuration. ips%d iobuf error A buffer input/output error has occurred. [ENXIO] General adapter errors: Attaching bus failed This message is undocumented. WARNING: command timeout. Adapter is in toaster mode, resetting A command timeout has caused the adapter to be reset. AIEE! adapter reset failed, giving up and going home! Have a nice day An error occurred while attempting to reset the adapter. unable to get adapter configuration unable to get drive configuration There was an error when attempting to get configuration information. Adapter error during initialization. adapter initialization failed There was an error while attempting to initialize the adapter. adapter failed config check adapter clear failed There was an error while checking the adapter. device is disabled The adapter is disabled. resource allocation failed irq allocation failed irq setup failed The driver was unable to allocate resources for the device. Error messages due to DMA: can't alloc command dma tag can't alloc SG dma tag can't alloc dma tag for statue queue dmamap failed Failure to map or allocate DMA resources. Cache, buffer, and command errors: failed to initialize command buffers no mem for command slots! The ips driver will return [ENOMEM] in such cases. ERROR: unable to get a command! can't flush cache! ERROR: cache flush command failed! ERROR: unable to get a command! can't update nvram ERROR: nvram update command failed! ERROR: unable to get a command! can't sync cache! ERROR: cache sync command failed! ERROR: unable to get a command! can't sync cache! ERROR: etable command failed!

COMPATIBILITY

Unlike many of the other SCSI devices in DragonFly, the ips driver does not use the cam(4) SCSI subsystem.
