Enabling or disabling tape reservations

You can control how ONTAP manages tape device reservations by using the tape.reservations option. By default, tape reservation is turned off.

Enabling the tape reservations option can cause problems if tape drives, medium changers, bridges, or libraries do not work properly. If tape commands report that the device is reserved when no other storage systems are using the device, this option should be disabled.

To use either the SCSI Reserve/Release mechanism or SCSI Persistent Reservations or to disable tape reservations, enter the following command at the clustershell: options -option-name tape.reservations -option-value {scsi | persistent | off}

scsi selects the SCSI Reserve/Release mechanism.

persistent selects SCSI Persistent Reservations.

off disables tape reservations.
