Air Cleaner User Manual

Note: SysBack supports any device supported that is support by AIX and does not
require it’s own proprietary drivers or software to operate. For a list of the
devices explicitly supported / tested by AIX, at your operating system level,
please see the file: /usr/lpp/bos.sysmgt/README.oem_writers
We have specifically tested at the following levels:
v cdrecord 1.9.0.0
v cdrtools 1.10.23
We support the use of these levels of said GNU Tools as well as later levels
provided through AIX maintenance level releases or the AIX for Linux Toolbox.
GNU Tools newer than what is distributed via AIX software updates may not
function consistently and support is not guaranteed. Once these GNU Tools have
been installed using the instructions available with the download, you must create
the following symbolic links:
v ln -s /usr/samples/oem_crwriters/burn_cd_gnu /usr/sbin/burn_cd
v ln -s /usr/samples/oem_crwriters/mkrr_fs_gnu /usr/sbin/mkrr_fs
Important Considerations
Backups to a CD or DVD device have their own caveats to consider. Such as:
Space
The creation of backups to CD or DVD devices requires large amounts of free
space on your system. You will need to ensure that you have enough space
available to perform this process before beginning. There is a flag on the
/usr/sbin/mksbcd command that will allow the process to estimate the required
amount of free space without actually creating the CD or DVD and backup image.
However, below are the guidelines to use for determining if you have enough free
space on your system This process will create 3 separate file systems for this
process.
v The backup_image is generated to a file system named by default
/mksbcd/backup_image. The size of this file system must be equal to the size of
your backup. For example: If you are backing up rootvg only, and you have a 4
GB root volume group, this file system will have to be 4 GB in size. Likewise, if
you are backing up rootvg and datavg, where rootvg is 4 GB and datavg is 7
GB, this file system will have to be 11 GB in size.
v The cd_fs is used as a staging area to create and build boot images, additional
software needed for cloning to alternate architectures, software that you choose
to optionally install onto the destination system, and portions of the backup
image as it is split into media sized pieces. The default file system created is
/mksbcd/cd_fs. The size of this file system must be equal to the size of your
media. For example: If you are using 4.5 GB DVD-RAM media, this file system
would have to be 4.5 GB. Likewise, if you are using 9.1 GB DVD-RAM double
sided media, this file system would still only be 4.5 GB as it is only equal to one
side of the media since only one side of the media can be burned at a time.
v The cd_image file system is also called the Rockridge file system since there is
where the Rockridge image (iso image) is stored while the CD or DVD burn is
in progress. The image in this file system is created from the cd_fs contents. The
default file system created is named /mksbcd_cd_image. This size of this file
system must be equal to the size of your media. For example: If you are using
4.5 GB DVD-RAM media, this file system would have to be 4.5 GB. Likewise, if
you are using 9.1 GB DVD-RAM double sided media, this file system would still
only be 4.5 GB as it is only equal to one side of the media since only one side of
the media can be burned at a time.
