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.
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.
