NAME

6       sdcard - SD/MMC memory card driver
7

DESCRIPTION

9       The  sdcard  memory  card  driver supports MultiMediaCard (MMC), Secure
10       Digital (SD), and Secure Digital High Capacity (SDHC) memory cards.  It
11       uses  the  blk2scsa(7D) service to present these cards to the system as
12       SCSI disks on a virtual SCSI bus, creating a child device  to  be  ser‐
13       viced  with  sd(7D).  Each  card appears as its own SCSI LUN. Cards are
14       hot-pluggable and removable.
15

DEVICE SPECIAL FILES

17       Disk block special file names are located in /dev/dsk. Raw  file  names
18       are located in /dev/rdsk.  See sd(7D).
19

IOCTLS

21       See dkio(7I)
22

ERRORS

24       See sd(7D) and blk2scsa(7D). Additionally, sdcard may issue the follow‐
25       ing warnings, which indicate a failure to identify the card as  a  sup‐
26       ported type:
27
28         "Unknown SD CSD version (%d)"
29         "Unknown MMC CSD version (%d)"
30         "Unknown MMCA version (%d)"
31         "Card type unknown"

FILES

35       Device special files for the storage device are created in the same way
36       as those for a SCSI disk. See sd(7D) for more information.
