9.5 Mounting Volumes
Table 9–13 (Cont.) MOUNT Command Qualifiers for Mounting Disks
Qualifier Description
/CLUSTER Requires SYSNAM privilege; specifies that after a volume is successfully
mounted on the local node, or if it is already mounted with the /SYSTEM
qualifier on the local node, it is to be mounted on every other node in the
existing OpenVMS Cluster environment (that is, the volume is to be mounted
clusterwide). For example:
$ MOUNT/SYSTEM/CLUSTER DUA1: SALES_95
/COMMENT="string" Specifies additional information to be included with the operator request when
the mount operation requires operator assistance. For example:
$ MOUNT/SYSTEM DYA1: SALES_95/COMMENT="Vol. in Rack 2."
/EXTENSION=n Requires OPER privilege; specifies the number of blocks by which disk files
are to be extended on the volume unless otherwise specified by an individual
command or program request. The cluster size sets the initial disk block
allocation; the /EXTENSION qualifier determines how the file grows. For
example, for a small disk with a cluster size of 1 disk block, you might select
an extension size of 2 disk blocks:
$ MOUNT/EXTENSION=2 DUA3:
/FOREIGN Indicates that the volume is not in the standard format used by the operating
system. Use this qualifier if you want to mount a disk volume with a file
structure other than Files–11 or ISO 9660; for example (using DISK as a
logical name):
$ MOUNT/FOREIGN DISK
/MEDIA_
FORMAT=CDROM
Mounts a volume assuming the media to be ISO 9660 (or High Sierra)
formatted.
/[NO]MOUNT_
VERIFICATION
Enables or disables the mount verification feature on disks. By default, the
mount verification feature is enabled. If a device goes off line or becomes
write-locked, mount verification notifies the operator of the error condition,
and then checks to see that the volume identification before and after the error
condition are identical.
To disable mount verification, enter a command like the following one:
$ MOUNT/SYSTEM/NOMOUNT_VERIFICATION DUA1: ACCOUNTS_DUE
/OVERRIDE=keyword Inhibits one or more protection checks that the MOUNT command performs.
/PROTECTION=keyword Specifies the protection code to be assigned to the volume. Keywords are in
the following list:
• Protection code: specifies the protection code according to the
standard syntax rules for specifying user protection (that is,
system/owner/group/world).
• XAR: enables enforcement of the extended record attribute (XAR) access
controls (ISO 9660 only).
• DSI: enables XAR permissions owner and group for XARs containing
DIGITAL System Identifiers (DSI). (ISO 9660 only.)
See Section 9.4.1 for details.
