28 /SYSTEM
Requires a system UIC or SYSPRV (system privilege) privilege.
Defines a system volume. The owner UIC defaults to [1,1].
Protection defaults to complete access by all ownership
categories, except that only system processes can create top-
level directories.
29 /USER_NAME
/USER_NAME=name
Specifies a user name to be associated with the volume. The name
must be 1 to 12 alphanumeric characters. The default is your user
name.
30 /VERIFIED
/VERIFIED
/NOVERIFIED
Indicates whether the disk has bad block data on it. Use the
/NOVERIFIED qualifier to ignore bad block data on the disk. The
default is the /VERIFIED qualifier for disks with 4096 blocks or
more and the /NOVERIFIED qualifier for disks with less than 4096
blocks.
31 /VOLUME_CHARACTERISTICS
/VOLUME_CHARACTERISTICS=([[NO]HARDLINKS,] [[NO]ACCESS_
DATES[=delta-time]],[NO]SPECIAL_FILES)
Applies to Files-11 On-Disk Structure Level 5 (ODS-5) disks only.
Enables or disables hardlinks and automatic updates of access
dates on ODS-5 volumes.
The default value for delta-time is 1 second, chosen to comply
with the "seconds since EPOCH" time interface required by
POSIX st_atime. A site can choose a larger delta time to reduce
overhead if 1-second granularity is not required.
Note that the NOACCESS_DATES option affects only the node on
which the command is issued. Other nodes are not affected by the
change until the next time the volume is mounted.
See the Guide to OpenVMS File Applications for additional
information.
The volume characteristic [SPECIAL_FILES] allows you to disable
symlinks. This eliminates file access failure audits that may
occur due to symlinks being enabled for all processes in the
current implementation.
32 /WINDOWS
/WINDOWS=n
Specifies the number of mapping pointers (used to access data in
the file) to be allocated for file windows. The value can be an
integer in the range of 7 to 80. The default is 7.
