DESCRIPTION
The sdcard memory card driver supports MultiMediaCard (MMC), Secure
Digital (SD), and Secure Digital High Capacity (SDHC) memory cards. It
uses the blk2scsa(7D) service to present these cards to the system as
SCSI disks on a virtual SCSI bus, creating a child device to be ser‐
viced with sd(7D). Each card appears as its own SCSI LUN. Cards are
hot-pluggable and removable.
DEVICE SPECIAL FILES
Disk block special file names are located in /dev/dsk. Raw file names
are located in /dev/rdsk. See sd(7D).
IOCTLS
See dkio(7I)ERRORS
See sd(7D) and blk2scsa(7D). Additionally, sdcard may issue the follow‐
ing warnings, which indicate a failure to identify the card as a sup‐
ported type:
"Unknown SD CSD version (%d)"
"Unknown MMC CSD version (%d)"
"Unknown MMCA version (%d)"
"Card type unknown"
FILES
Device special files for the storage device are created in the same way
as those for a SCSI disk. See sd(7D) for more information.

/dev/rdsk/cntndnsn Raw files for disks
