Automated cartridge mounts/dismounts are performed in response to calls to the tape 
management interface. The HSC determines that a mount/dismount is required for a 
volume under automated library control (cartridge resides in an LSM storage cell), and it 
communicates with the appropriate LMU. 

If the request is for a mount, the following information is communicated to the LMU: 

• the LSM and panel/row/column in which the volume resides 
• the destination LSM (where the volume is to be mounted on a transport). 

If all drives in an LSM are busy, a cartridge can be moved to another LSM to satisfy the 
mount request. This action is performed without operator intervention, since the pass-thru 
port (PTP) makes the cartridge available to the attached LSM.

If the request is for a dismount, this information is passed to the LMU: 

• the LSM, cartridge drive, and transport in which the volume resides 
• the destination (storage cell, CAP, or PTP) of the cartridge.
