4.12 Burning disks/writing incremen-
tally
It is possible to write data to disks in two ways with iXOS-JUKEMAN,
namely, in batch mode or incrementally and transparently using the file
system.
Batch mode was also a feature of version 1.3b of iXOS-JUKEMAN. The
writeable disks are placed in the jukebox and the recorder is reserved for
the write process. Once JUKEMAN is instructed to insert a disk into the
appropriate drive, the burning process begins in the same way as a disk
would be burned in a normal stand-alone drive. Finally the disk is returned
to its original slot. It is then possible to include this disk into the overall
group of disks, which are an already visible and accessible part of the file
system, by clicking on Test (c.f. “Manage disks” on page 112). In this way
you achieve a visible migration of data: First the data is collected on a
hard disk, before it is written to the disk to be burned and finally integrated
into the file system. The drive used for burning is reserved by deactivating
same in the device description file (see also “Drive set-up” on page 54). It
is also possible to reserve the required drive dynamically during normal
operation of the jukebox (e.g to reserve drive 1, simply use the command
cdadm detach jb.dev -d 1). It is then possible to move a disk to this
drive with the command cdadm movecd jb.dev 1 <slot> or remove a
disk from this drive with the command cdadm movecd jb.dev 1. When
the drive no longer needs to be reserved, it can be used again for reading
with the command cdadm attach jb.dev -d 1.
