6 sdcard - SD/MMC memory card driver
7
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
17 Disk block special file names are located in /dev/dsk. Raw file names
18 are located in /dev/rdsk. See sd(7D).

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"

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.
