• If initialization is successful, it generates a not-ready to ready

transition (

SK=6 ASC=28 ASCQ=00), otherwise, failure sense data is

set accordingly.

SuperLoader 3 Offline 1

When a user accesses the SuperLoader 3 via the front panel or On-board

Remote Management in such a way that would cause conflict with a SCSI

command, the SuperLoader 3 is put into an off-line state. If a SCSI

command is received while in this off-line state, a not ready check

condition is reported (

SK=02 ASC=04 ASCQ=07).

Magazine Insertion/

Removal 1

The SuperLoader 3 must be powered-on with at least one magazine,

otherwise a check condition is reported (

SK=02 ASC=04 ASCQ=03).

While the system is on-line, the user may remove a magazine blank and

replace it with a magazine. The SuperLoader 3 will calibrate the newly

installed magazine and check the presence of tape cartridges in each of

the storage elements. While this inventory is in progress, the

SuperLoader 3 will report a not-ready check condition (

SK=02 ASC=04

ASCQ=01

). Once the inventory is complete, the SuperLoader 3 reports a

unit attention (

SK=06 ASC=3B ASCQ=13).

Similarly, while a magazine is in the process of being removed, a

not-ready check condition is reported (

SK=02 ASC=04 ASCQ=07). Once the

operation is complete, by replacing the magazine with a blank a unit

attention is reported (

SK=06 ASC=3B ASCQ=12).

While one or both of the magazine bays are open, a not ready check

condition is reported (

SK=02 ASC=04 ASCQ=03).

Maximum Temperature

Exceeded 1

The SuperLoader 3 monitors the ambient temperature within the system.

If the temperature exceeds the maximum safe temperature for the media,

the SuperLoader 3 will disable all movement until the temperature

decreases below a safe threshold. While the temperature remains

excessive, SCSI commands that require movement will fail (

SK=04

ASC=0B ASCQ=01
