Using the crash(ADM) diagnostic tool

Examining the values of kernel tunable parameters

Use the var command of crash(ADM) to view the values of the major tunable kernel parameters:

> var
v_buf:  30
v_call:  60
v_clist:  12
v_maxup:  20
v_hbuf:   8
v_hmask:   7
v_pbuf:   2
v_nofiles:  60
v_inode:  75		ve_inode:  75
v_s5inode:  75
v_file:  75             ve_file:  75
v_mount:  4             ve_mount:  4
v_proc:  75             ve_proc:  9
...
This report shows the current values of the tunable parameters in the var structure, defined in the <sys/var.h> header file. The names of the values displayed here correspond to those of the tunable parameter; for example, v_proc contains the value of NPROC and v_file contains the value of NFILE. Comments in the header file indicate the tunable for each member and can be used as a reference.

See UNRESOLVED XREF-0 for more information about the kernel parameters and how you can change them.
