NAME

6       removable-media - removable media device property
7

DESCRIPTION

9       A  device  that  supports  removable media—such as CDROM, JAZZ, and ZIP
10       drives—and that supports power management and expects automatic  mount‐
11       ing  of  the  device  via  the volume manager should export the boolean
12       (zero length) property removable-media. This property enables the  sys‐
13       tem  to make the power state of the device dependent on the power state
14       of the frame buffer and monitor. See the  power.conf(4)  discussion  of
15       the device-dependency-property entry for more information.
16
17
18       Devices that behave like removable devices (such as PC ATA cards, where
19       the controller and media both are removed at the same time) should also
20       export this property.

EXAMPLES

23       Example 1 removable-media Entry
24
25
26       An  example  of a removable-media entry from the .conf file of a driver
27       is shown below.
28
29
30         # This entry keeps removable media from being powered down unless
31         # the console framebuffer and monitor are powered down
32         #
33         removable-media=1;

36       Example 2 Implementation in attach()
37
38
39       Below is an example of how the entry above would be implemented in  the
40       attach(9E) function of the driver.
41
42
43         xxattach(dev_info_t *dip, ddi_attach_cmd_t cmd)
44              {
45              ...
46                   if (ddi_prop_create(DDI_DEV_T_NONE, dip, DDI_PROP_CANSLEEP,
47                       "removable-media", NULL, 0)) != DDI_PROP_SUCCESS)
48                        goto failed;
49              ...
50              }
