When performing load/eject operations for silo-type libraries (such as ACSLS or
DAS), consider the following:
• When you click Run Mount Cycle for the first time , silo libraries eject all media
listed on Premount Job - Dismount Listing during this first cycle (on non-silo librar-
ies, it only ejects one CAP’s worth of media). To eject the media from a silo library:
1. Wait for the CAP to be filled and unlocked. Open the CAP and remove all
media from it.
2. Close the CAP. Note that on some silo libraries, you must totally empty the
CAP before closing it, otherwise the library will not register that the CAP has
been emptied and will not proceed.
3. If there are more media to be ejected, repeat this sequence.
• You cannot put scratch media into the silo CAP until after you have clicked Run
Mount Cycle for the second and any subsequent times. Therefore, after performing
the initial eject cycle, proceed as follows:
1. Select the silo library from Premount Job - Load/Eject Media. Click Run Mount
Cycle.
2. Go to the silo library and wait for the CAP to unlock. Open the CAP and
load the required scratch media into it.
3. Close the CAP. The load starts.
4. After all media in the CAP are loaded, any media to be dismounted are
automatically unloaded into the CAP. This occurs only if there has been a
problem in the first mount cycle.
5. Wait for the unload to complete and the CAP to unlock. Open the CAP and
remove media from it.
6. Close the CAP to complete the load/eject cycle.
Free/scratch pool handling
A free/scratch pool is an auxiliary source of media when there are no scratch media
available in the regular pool. If a media pool, required for a premount job, is able
to use media from a dedicated free/scratch pool, you can select the scratch media
from either regular or free/scratch pool.
