RESERVE (10) Command (56h) SDLT 600 SCSI Interface Guide
4-228 January 2005 81-81200-02 REV A03
4.28 RESERVE (10) Command (56h)
NOTE: This command has been made obsolete in the latest version of SCSI-3 and
should not be used with any new implementations. The SDLT tape drive
supports this command for legacy applications only.
The RESERVE and RELEASE commands provide contention resolution in multiple-initiator systems.
The RESERVE command reserves a logical unit number. The RESERVE (10) CDB is shown in
Figure 4-122, and the data fields are described in Table 4-132. If RESERVE (10) is used, RELEASE
(10) must also be used.
