Breaking a reservation
If you cannot release an SPC-2 SCSI reservation, try to use an operating system command that forces a device reset. A device reset breaks a reservation. The procedure depends on the operating system type.
Note:
The reset operation can reset other devices in the configuration. Loss of data is also possible. Try alternate methods first to break the reservation on a device (by using switch and bridge hardware).
Lastly, if the following operating system commands cannot break the reservation, power-cycle the drive. A power cycle breaks SPC-2 SCSI drive reservations (and usually breaks SCSI persistent drive reservations).
To break an SPC-2 reservation on Solaris
- Issue mt -f drive_path_name forcereserve.
- Issue mt -f drive_path_name release.
See the mt(1) man page for more information.
