NAME
norewind_close_disabled - determine whether access to tape device special files without the no-rewind-on-close option is allowed
VALUES
Default
Allowed values
DESCRIPTION
Note: this tunable was named in releases prior to HP-UX 11i v3.
This tunable notifies the tape driver whether it should allow access to device special files without the no-rewind-on-close option. When
this tunable is on, the tape driver will fail any open on a tape device special file that does not have the no-rewind-on-close option (that
is, or with a status of
The tunable allows the safe sharing of tape devices in SAN tape backup solution configurations. The disabling of device special files
without no-rewind-on-close in a SAN tape backup solution configuration prevents the accidental sending of a rewind command on close from
HP-UX systems via standard tape commands like which would corrupt a backup in process.
Who Is Expected to Change This Tunable?
Anyone.
Restrictions on Changing
Changes to this tunable take effect immediately.
When Should the Tunable Be Turned On?
This tunable should be turned on if the system is going to be used in a SAN tape backup solution configuration.
What Are the Side Effects of Turning the Tunable On?
The tape driver will fail any open to a tape device special file that does not have the no-rewind-on-close option with a status of This
behavior prevents the usage of any tape device special file without the no-rewind-on-close option.
When Should the Tunable Be Turned Off?
This tunable should be turned off if the system is not part of a SAN tape backup solution configuration or the system utilizes will not
function unless it has access to device special files without the no-rewind-on-close option.
What Are the Side Effects of Turning the Tunable Off?
A rewind may be issued accidentally from this system on close, possibly corrupting a backup being issued from another system on the SAN.
What Other Tunables Should Be Changed at the Same Time?
None.
