Identifying an Unrecognized Device
If you insert a memory device and it isn’t recognized (no special files created), use
the prtconf command.
1. Become root.
2. Run the prtconf -D command to display the configuration recognized by the
system.
A recognized device will appear in the prtconf output. For example:
# prtconf -D
. . .
pcic, instance #0 (driver name: pcic)
. . .
memory, instance #0 (driver name: pcmem)
pcram, instance #0 (driver name: pcram)
3. If your memory device does not appear at the end of the prtconf output, it is
not supported and cannot be used with the pcram device driver.

in the form /dev/dsk/c#t#d#p# or /dev/dsk/c#t#d#s# (see pcram(7D)).
