mediainit(1) mediainit(1)

Some applications may require that a ﬁle system be placed on the media before use.

mediainit does

not create a ﬁle system; it only prepares media for writing and reading. If such a ﬁle system is required,

other utilities such as

newfs, lifinit,or

mkfs must be invoked after running mediainit (see

newfs(1M), liﬁnit(1), and mkfs(1M)).

RETURN VALUE

mediainit returns one of the following values:

0 Successful completion.

1 A device-related error occurred.

2 A syntax-related error was encountered.

ERRORS

Appropriate error messages are printed on standard error during execution of

mediainit.

WARNINGS

For a device that contains multiple units on a single controller, each unit can be initialized independently

from any other unit. It should be noted, however, that

mediainit requires that there be no other

processes accessing the device before initialization begins, regardless of which unit is being initialized. If

there are accesses currently in progress,

mediainit aborts.

Aborting mediainit is likely to leave the medium in a corrupt state, even if it was previously initialized.

To recover, the initialization must be restarted.

During the initialization process,

open() rejects all other accesses to the device being initialized, produc-

ing the error

EACCES (see open(2)).

DEPENDENCIES

Series 800

Partitioning of DDS tape media (

-p option) is not supported.
