- _u_n_c_o_m_p_v_m expands IRIX vmcore.n.comp files into standard vmcore.n files.
-
- Under some circumstances, an IRIX operating system core dump may be made
- in a special compressed format. Running _f_i_l_e(1) on a vmcore.n.comp file
- yields something like the following:
-
- vmcore.0.comp: IRIX vmcore dump of 'IRIX abu stever-j 03080214 IP19'
-
- _u_n_c_o_m_p_v_m without any command-line options uncompresses these into files
- of up to the size of the physical memory on the system that created the
- dump. For this reason, it may not be advisable to expand such dumps. If
- _o_u_t_f_i_l_e is not specified, _u_n_c_o_m_p_v_m expands the dump into vmcore.n without
- the .comp extension.
-
- The options are:
-
- ----hhhh Header mode. In header mode, _u_n_c_o_m_p_v_m does not
- uncompress the entire dump file, but rather decodes the
- dump header which contains information about the system
- and the reason it created a vmcore file.
-
- ----HHHH Long header mode. Like header mode, but it prints a more
- complete accounting of the information in the dump
- header.
-
- ----dddd Debug mode. Useful only for debugging _u_n_c_o_m_p_v_m.
-
- ----vvvv Verbose mode. Prints additional information for each
- block of the _c_o_r_e_n_a_m_e.
-
- ----ssss _m_a_x__m_b_y_t_e_s Specifies the maximum size of the expanded vmcore.n file
- in megabytes.
-
- ----bbbb _b_l_o_c_k__n_u_m_b_e_r Print detailed information about a particular
- _b_l_o_c_k__n_u_m_b_e_r. The _b_l_o_c_k__n_u_m_b_e_r of interest can be
- possibly obtained by first running the 'uncompvm -b list
- corename'. (Output goes to stdout).
-
- ----bbbb _l_i_s_t Print specific header information for each block of the
- _c_o_r_e_n_a_m_e. (Output goes to stdout, generates lots of
- output!).

-
- ----bbbb _c_h_e_c_k _u_n_c_o_m_p_v_m will read all _c_o_r_e_n_a_m_e and verify the
- completeness and correctness of the _c_o_r_e_n_a_m_e dump. No
- output will be generated unless errors were detected.
-
- When -b is specified, _u_n_c_o_m_p_v_m will not generate the uncompressed _o_u_t_f_i_l_e
- even if the _o_u_t_f_i_l_e has been specified on the _u_n_c_o_m_p_v_m call. The -b
- option is useful to see more in details the internals of the _c_o_r_e_n_a_m_e and
- it is thus most used by developers.

-
-
- This uncompresses vmcore.0.comp into vmcore.0, truncating the size of
- vmcore.0 to 16 megabytes if necessary.

- This will read through the coredump and verify its correctness and
- completeness. No output will be generated unless errors were detected.
