RELEASE UNIT Command (17h) (continued)
Table 5–63 RELEASE UNIT Command Data - Field Descriptions
Field Name
Description
3rdPty
The third party release option for RELEASE UNIT allows an initiator to
release a logical unit that was previously reserved using the third-party
reservation option. If this bit is 0, then the third-party release option is not
requested. If this bit is set to 1, the drive is released if it was originally
reserved by the same initiator using the third-party reservation option and
if the tape drive is the same SCSI device specified in the Third Party Device
ID field.
Third Party Device ID
Required if the 3rdPty bit is 1. This field specifies the SCSI ID of the initiator
whose third party reservation is being released. This field must be set if the
initiator of the original third party RESERVE is the source of the RELEASE.
Media Changer Considerations
The optional Element reservation feature defined for Medium Changer devices in
the SCSI-2 ANSI specification is not supported. The RELEASE command is
defined the same as for the tape drive. The whole loader unit can be released.
RESERVE / RELEASE of the Loader and Drive LUNs are handled
independently.
