SCSI Description

4'5'48'%QOOThe RESERVE and theCPFJRELEASE commands are used for contention resolution in multiple-initiator systems. The RESERVE command is used to reserve a logical unit. The data format and the field descriptions are described in Table 5-186and Table 5- 187 respectively.

RESERVE (6) Command-Field Descriptions

3rd(KGNFPty

When set to 1, it indicates that the Third&GUETKRVKQPParty Device ID field is valid.

Required and used only when the 3rdPty bit is set, in which case this field specifies the

SCSI ID (0 through only) of the initiator to be granted the reservation of the logical unit.

The drive preserves the reservation until one of the following occurs:

• It is superseded by another valid RESERVE command from the initiator.

Third

• It is released by the same initiator

• It is released by a TARGET RESET message from any initiator.

Party

• It is released by a hard reset condition.

Device ID

Table

-186

The drive ignores any attempt to release the reservation made by any other initiator. For

example, if ID7 sends ID2 a Third Party reservation on behalf of ID6 (the target at ID2

gets reserved for the initiator ID6), then only ID7 can release the target at ID2 (using a

Third Party release). ID6 cannot release the reservation even though the reservation was

made on its behalf.

Extent

The drive supports reservations only on entire logical units. The value must be 0.

Note:

The drive returns RESERVATION CONFLICT status if the unit is already

reserved for another initiator. Once the reservation is honored, any command

from another initiator (except INQUIRY or REQUEST SENSE) is rejected

with RESERVATION CONFLICT status. Maxtor Atlas 10K III
