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. It will prevent the driver from attaching.

HARDWARE

Controllers supported by the ips driver include:

IBM ServeRAID 3H
ServeRAID 4L/4M/4H
ServeRAID Series 5
ServeRAID 6i/6M

DIAGNOSTICS

Several error codes may be shown when the card initializes the IBM ISPR utility and are independent of
.Fx .

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
.Fx , the ips driver does not use the cam(4) SCSI subsystem.
