Add loopback devices OEL6 (ASM)

Add 2 loopback devices using "mknod","chmod" and "chown" commands ...

# ls -l /dev/loop*
# mknod /dev/loop8  b 7 8
# mknod /dev/loop9  b 7 9
# chmod 660 /dev/loop8
# chmod 660 /dev/loop9
# chown root:disk /dev/loop8
# chown root:disk /dev/loop9
# ls -l /dev/loop*

Add 10 loopback devices using "MAKEDEV" command ...

# ls -l /dev/loop*
# MAKEDEV -v /dev/loop8
# ls -l /dev/loop*

And finaly add up to 256 loopback devices again with the "MAKEDEV" command ...

# ls -l /dev/loop*
# MAKEDEV /dev/loop
# ls -l /dev/loop* | sort -gk6 | head -20
# ls -l /dev/loop* | wc -l

If you want to clean some of them ... (use carefully) ...

# for i in `seq 8 255`; do;
# rm -f /dev/loop${i};
# done

Don't forget to put the "MAKEDEV" or "mknod"+"chmod"+"chown" commands in the "/etc/rc.local" file if you want to get them back after reboot.
