You can issue the Mode Sense command to determine the
SuperLoader configuration. You can also use this command to
determine the first address and the number of elements of each
type.
Although the SuperLoader does have a mailslot, it is not reported
as an Import/Export element for use by the host system. It is
strictly to allow users to access tape cartridges using the front
panel or On-board Remote Management tool.
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.
Data Transfer
Element
1
The SuperLoader is configured with a single tape drive.
Storage Elements
1
All of the storage elements within the SuperLoader are contained
within removable magazines. There are two magazines which hold
eight tape cartridges each, for a total of 16 storage elements. Since
the magazines are removable, a user may insert or remove a
magazine at any time. Because of this, the SuperLoader always
reports 16 storage elements, regardless of how many magazines
are currently installed. When a magazine is removed, the
corresponding storage elements are reported as inaccessible. This
is done via the Read Element Status–
on page 134–byte 2, bit 3.
Events
1
Events are system conditions created y operator actions or system
failures. These events are recorded in sense data for the SCSI host
to retrieve via the Request Sense command.
