Quantum SuperLoader 3 Software Interface Guide 3
Medium Transport
Element 1
This mechanism can hold a single cartridge and is considered a single
medium transport element. It is used to move media between elements
within the SuperLoader 3.
Data Transfer Element 1
The SuperLoader 3 is configured with a single tape drive.
Storage Elements 1
All of the storage elements within the SuperLoader 3 are contained
within removable magazines. There are two magazines which hold eight
tape cartridges each, for a total of 16 storage elements. The number of
storage elements is either 8 or 16 depending on how the magazines are
configured via the front panel or the On-board Remote Manager. When a
configured magazine is removed, the corresponding storage elements are
reported as inaccessible. This is done via the
Read Element Status–
“
Storage Element Descriptor” on page 107–byte 2, bit 3.
Events
Events are system conditions created by operator actions or system
failures. These events are recorded in sense data for the SCSI host to
retrieve via the
Request Sense command.
Power Cycle 1
When the SuperLoader 3 is powered-on, it goes through an initialization
sequence during which it:
• Resets and initializes all hardware
• Responds to SCSI commands which do not require movement
• Responds to
Test Unit Ready and all movement type commands with
a not ready, initialization in progress check condition (
SK=02 ASC=29
ASCQ=02
).
When the power on initialization is complete, it:
• Generates a
Power On/Reset Occurred event (SK=6 ASC=29 ASCQ=02)
