Full Discussion: Lun remove, stuck in /dev/dsk and /dev/rdsk
Operating Systems Solaris Lun remove, stuck in /dev/dsk and /dev/rdsk Post 302800653 by DustinT on Tuesday 30th of April 2013 08:13:50 AM
Old 04-30-2013
under /dev/cfg I have the following

Code:
bash-3.2# ls
c0  c1  c2
bash-3.2# cat c2
cat: input error on c2: No such device or address
bash-3.2# cd c2
bash: cd: c2: Not a directory

I have other LUNS off of c2 that I don't want to lose. How do I go about removing that reference since c2 isn't a file I can edit??

sysdef

sysdef(1M)                                                System Administration Commands                                                sysdef(1M)

NAME

       sysdef - output system definition

SYNOPSIS

       /usr/sbin/sysdef [-i] [-n namelist]

       /usr/sbin/sysdef [-h] [-d] [-i] [-D]

DESCRIPTION

       The  sysdef utility outputs the current system definition in tabular form. It lists all hardware devices, as well as pseudo devices, system
       devices, loadable modules, and the values of selected kernel tunable parameters.

       It generates the output by analyzing the named bootable operating system file (namelist) and extracting the configuration information  from
       it.

       The default system namelist is /dev/kmem.

OPTIONS

       -i              Prints  the  configuration information from /dev/kmem. This is the default and only needs to be specified if the configura-
                       tion information from both /dev/kmem and the system file specified with the "-n namelist" option is needed.

       -nnamelist      Specifies a namelist other than the default (/dev/kmem). The namelist specified must be a valid bootable operating system.

       -h              Prints the identifier of the current host in hexadecimal. This numeric value is unique across all Sun hosts.

       -d              The output includes the configuration of system peripherals formatted as a device tree.

       -D              For each system peripheral in the device tree, display the name of the device driver used to manage the peripheral.

EXAMPLES
