 There are several RAID types of HW/SW and drivers that are in use. There are several methods available depending on the HW/SW/drivers in use.

Couple of examples; acaraid & megaraid & megaraid2

What HW and/or drivers are in the system? Can use ther 'lshw' utility to see HW and 'lsmod' to see your modules loaded in kernel. (lshw is a download tool).

There are some provided with GUI tools as well.

 Use 

tar xfv *.zip.tar

unzip [whatever file got untarred]

Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]

  Default action is to extract files in list, except those in xlist, to exdir;

  file[.zip] may be a wildcard.  -Z => ZipInfo mode ("unzip -Z" for usage).

  -p  extract files to pipe, no messages     -l  list files (short format)

  -f  freshen existing files, create none    -t  test compressed archive data

  -u  update files, create if necessary      -z  display archive comment

  -x  exclude files that follow (in xlist)   -d  extract files into exdir

modifiers:                                   -q  quiet mode (-qq => quieter)

  -n  never overwrite existing files         -a  auto-convert any text files

  -o  overwrite files WITHOUT prompting      -aa treat ALL files as text

  -j  junk paths (do not make directories)   -v  be verbose/print version info

  -C  match filenames case-insensitively     -L  make (some) names lowercase

  -X  restore UID/GID info                   -V  retain VMS version numbers

  -K  keep setuid/setgid/tacky permissions   -M  pipe through "more" pager

Examples (see unzip.txt for more info):

  unzip data1 -x joe   => extract all files except joe from zipfile data1.zip

  unzip -p foo | more  => send contents of foo.zip via pipe into program more

  unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer

 Use the chkconfig command to configure Apache to start at boot:

[root]# /etc/init.d/httpd stop
[root]# /etc/init.d/httpd restart

[root]# pgrep httpd

 [root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

#vi /etc/sysconfig/network-scripts/ifcfg-eth0

press "SHift+i"

BOOTPROTO=static
