Virtual Optical Device, Virtual Optical Drive and Virtual Media Library

1. To create a virtual media repository:
# mkrep -sp rootvg -size 10G

Above command will create a filesystem called /var/vio/VMLibrary.

2. To create an iso from from AIX DVD:
# dd if=/dev/cd0 of=/cg/AIX61-1.iso bs=1m

You can copy the iso file to /var/vio/VMLibrary.

3. To list the contents of virtual media repository:
$ lsrep
Size(mb) Free(mb) Parent Pool         Parent Size      Parent Free
   10198     5828 rootvg                   139776           110592

Name                                    File Size Optical         Access
AIX61_1.iso                              3679 vtopt0          rw
AIX61_2.iso                               691 None            rw

4. To create a Virtual Optical device :
# mkvdev -fbo -vadapter vhost0

5. To create a virtual optical media from a downloaded ISO image:
# mkvopt -ro -name aix61 -file /home/padmin/aix61.iso

6. To remove a virtual optical media:
# rmvopt -name aix61

7. To list all the virtual optical devices:
# lsvopt

8. To load the virtual optical media on a virtual optical device:
# loadopt -vtd vtopt0 -disk linux

9. To load an ISO file on a virtual optical device:
# loadopt -vtd vtopt0 -disk AIX61_1.iso

10. To check if the ISO was loaded correctly:
# lsmap -vadapter vhost0

11. To unload the virtual media from virtual optical device:
# unloadopt -vtd vtopt0

12. To force remove the virtual media:
# unloadopt -vtd vtopt0 -release

IP Alias

You can set IP alias on any network interface (such as en0, en1,..) temporarily (using ifconfig command) or permanently (by adding entry in ODM) in AIX. Here are some commands which you may refer whilst working on this concept.

To temporarily add IP alias :
You can use the below command to set IP alias temporarily ie., the alias will be lost after a server reboot.
#ifconfig en0 alias 192.168.1.2 netmask 255.255.255.0 up

To permanently add IP Alias :
Below command will amend the ODM entry, so the alias will be available even after a server reboot.
# chdev -l en0 -a alias4=192.168.1.2,255.255.255.0

To remove a temporary IP alias :
This would remove the alias from the current  ip table, but it would not remove from the ODM. If you like to erase it from ODM, then use the "chdev" or "smitty".
# ifconfig en0 delete 192.168.1.2

To remove IP alias permanently :
This command will work only if IP alias was added in ODM using smitty or chdev command. If you have added using "ifconfig" command, then it is set temporarily, so this command would not work.
#chdev -l en0 -a delalias4=192.168.1.2,255.255.255.0

To display current IP table including IP alias :
# ifconfig -a

To display permanently added IP alias :
# lsattr -El en0
