DEVICES IN SOLARIS

1. If the Solaris Fault Management system detects a problem with a device, mes-
sages about the problem can be displayed by using the following command

# fmdump

NOTE: Messages are also traditionally written to the console and to the /var/adm/messages file. If the Fault Management system takes a device offline, the message “(retired)” is displayed in the prtconf output.

2. To view the device information from shell run the following command

# prtconf

NOTE:  It also give the amount of system memory available in our system. 

3 . To display the driver being used for the corresponding devices

# prtconf -D

4. To view the more output

# prtconf -pv

NOTE: The advantage of prtconf is it can be run by any user.

X86 based Systems
--------------------------------

In x86 based systems we can display the device information using


# /usr/X11/bin/scanpci

or

# /usr/X11/bin/scanpci  -v  ( It provide more verbose output )

####KERNEL MODULES IN SOLARIS #########################

The location of kernel modules in Solaris is as follows.

/kernel/drv (default location for most leaf-node drivers)
/kernel/misc
/usr/kernel/drv
/usr/kernel/misc
/platform/i86pc/kernel/drv
/platform/i86pc/kernel/misc

5.To check the Loaded Modules information
------------------------------------------------------------

# modinfo | grep driver name


6.To determine whether the kernel is running in 32 or 64 bit mode

# lsainfo -kv


7. To manually load a kernel module

# modload /kernel/drv/amd64/e1000g

# modinfo | grep  e1000g

8. To get more verbose driver module information

# strings /kernel/drv/amd64/e1000g | grep -i  ver

9.To check which drivers are bound to which devices

# cat  /etc/driver_aliases

NOTE: The file has the format of driver name followed by device name
