NAME

sdfinit − initialize Structured Directory Format volume

SYNOPSIS

/etc/sdfinit [-i] pathname [blocksize [bootsize [interleave]]]

HP-UX COMPATIBILITY

Level: HP-UX/NUCLEUS

Origin: HP

Remarks: Not supported on the Integral PC. 

DESCRIPTION

Pathname refers to a character or block special file, which must be accessible and not mounted. 

Blocksize is the number of bytes per logical block.  It is rounded up, if necessary, to the next multiple of the physical record size for the volume.  If absent or less than one (1), the system sets a reasonable default for you. 

Bootsize is the number of bytes to allocate for the boot area on the volume.  It is rounded up to a whole number of logical blocks.  It defaults to zero (no boot area). 

Interleave is the sector interleave factor.  It defaults to one (not necessarily the best value for all devices). 

The root directory on the newly-initialized volume is always owned by the super-user and has permissions of 777. 

The -i option inhibits formatting and certification, so the volume is only initialized.  That is, only a directory structure is written.  This saves a considerable amount of time in most cases.  However, the -i option is NOT RECOMMENDED for most removable media, unless it was recently formatted and certified in the same type of drive. 

RESTRICTIONS

The effective user ID must be zero (super-user).  The disc must not be mounted. 

DIAGNOSTICS

Appropriate error messages are given if the argument list is incorrect, pathname cannot be initialized or any other error occurs.
