SIL_DEV_CONFIG(9) sata_sil Internals SIL_DEV_CONFIG(9)NAME
sil_dev_config - Apply device/host-specific errata fixups
void sil_dev_config(struct ata_device * dev);
Device to be examined
After the IDENTIFY [PACKET] DEVICE step is complete, and a device is known to be present, this function is called. We apply two errata
fixups which are specific to Silicon Image, a Seagate and a Maxtor fixup.
For certain Seagate devices, we must limit the maximum sectors to under 8K.
For certain Maxtor devices, we must not program the drive beyond udma5.
Both fixups are unfairly pessimistic. As soon as I get more information on these errata, I will create a more exhaustive list, and apply
the fixups to only the specific devices/hosts/firmwares that need it.
20040111 - Seagate drives affected by the Mod15Write bug are blacklisted The Maxtor quirk is in the blacklist, but I'm keeping the original
pessimistic fix for the following reasons... - There seems to be less info on it, only one device gleaned off the Windows driver, maybe
only one is affected. More info would be greatly appreciated. - But then again UDMA5 is hardly anything to complain about

TAPEINFO(1) General Commands Manual TAPEINFO(1)NAME
tapeinfo - report SCSI tape device info
tapeinfo -f <scsi-generic-device>
The tapeinfo command reads various information from SCSI tape drives that is not generally available via most vendors' tape drivers. It
issues raw commands directly to the tape drive, using either the operating system's SCSI generic device ( e.g. /dev/sg0 on Linux,
/dev/pass0 on FreeBSD) or the raw SCSI I/O ioctl on a tape device on some operating systems.
One good time to use 'tapeinfo' is immediately after a tape i/o operation has failed. On tape drives that support HP's 'tapealert' API,
'tapeinfo' will report a more exact description of what went wrong.
Do be aware that 'tapeinfo' is not a substitute for your operating system's own 'mt' or similar tape driver control program. It is intended
to supplement, not replace, programs like 'mt' that access your operating system's tape driver in order to report or set information.
The first argument, given following -f , is the SCSI generic device corresponding to your tape drive. Consult your operating system's doc-
umentation for more information (for example, under Linux these are generally start at /dev/sg0 under FreeBSD these start at /dev/pass0).
Under FreeBSD, 'camcontrol devlist' will tell you what SCSI devices you have, along with which 'pass' device controls them. Under Linux,
"cat /proc/scsi/scsi" will tell you what SCSI devices you have.
BUGS AND LIMITATIONS
This program has only been tested on Linux with a limited number of tape drives (HP DDS4, Seagate AIT).
tapeinfo is currently being maintained by Robert Nelson <firstname.lastname@example.org> as part of the 'mtx' suite of programs. The
'mtx' home page is http://mtx.sourceforge.net and the actual code is currently available there and via SVN from http://source-
