启动solaris后怎样重载外围设备

如果在启动solaris系统之后发现有的外围设备忘记了开启，可以通过以下命令来重载：

To gain access to the CD-ROM, you could halt the system, turn on power to the CD-ROM, and start the system backup, or you could simply turn on power to the CD-ROM and issue the following command at the command prompt:

devfsadm

When used without any options, devfsadm will attempt to load every driver in the system and attach each driver to its respective device instances. You can restrict devfsadm to only look at specific devices using the -c option as follows:

devfsadm -c disk -c tape

This restricts the devfsadm command to devices of class disk and tape. As shown, the -c option can be used more than once to specify more than one device class.

Now, if you issue the sysdef command, you'll see the following output for the CD-ROM:

sd, instance #6

You can also use the devfsadm command to configure only the devices for a specific driver such as "st" by using the -i option as follows:

devfsadm -i st

The devfsadm command will only configure the devices for the driver named "st."
