nbpi = number
Sets the number of bytes per inode (inode density) to number.
rotational_delay =
number
Sets the rotational delay factor for the file system to number. (See tunefs (1M).)
largefiles = boolean
Specifies that largefiles are to be enabled or disabled for this volume. This is supported for both
HFS and VxFS file systems.
version = number
For HP-UX B.11.23 and later clients, this keyword specifies the disk layout version number of the
VxFS file system to create for a mount point. If this keyword is not specified for a VxFS mount
point, then the default value for the release is used. For B.11.23, this value is
5; for B.11.31 this
value is
6. This is only supported for VxFS file systems.
The following attributes are recognized when the volume is an LVM volume (see lvcreate (1M)). Those
that apply to VxVM volumes are noted as such, otherwise they are ignored if the disk group is VxVM.
bad_block_relocate =
boolean | none
Sets the bad block relocation policy to ’y if boolean is
true or n if boolean is false.If
none is
given, the bad block relocation policy is set to N’.
contiguous_allocation =
boolean
Sets the contiguous allocation policy to ’y’ if boolean is
true or ’n if boolean is
false. Also applies
to VxVM volumes.
stripes = number
stripes = *
Specifies the data for this logical volume should be striped across multiple physical disks in the
volume group. The number of disks used to stripe the data may be provided by number,orifthe
data should be striped across all the disks in the group,
* may be specified. Volumes that must be
contiguous (/, /stand, and primary swap/dump) cannot be striped. There must be two or more
disks configured in the volume group in order to specify a striped volume in that group. Also
applies to VxVM volumes.
stripe_size = number
Specifies the data size of each stripe. This is only used when the logical volume is specified to be
striped via the stripes keyword. The default stripe_size is equal to the file system block
size (which is 8KB by default). The allowed values for number depend on the usage. If the
usage is LVM then the allowed values for number must be a power of 2 and be in the range of 4KB
to 32MB. If the usage is VxVM the allowed values can be any size.
disk[hw_path|dev_spec
]
Specifies one or more references to a disk that may be listed inside a logical volume definition.
Doing so will force that volume to have data allocated only from the disk or disks listed. The disks
are listed inside the logical volume must have been listed as physical_volumes
in the same
volume group in which the logical volume exists. Unless the desired disks are listed within the logi-
cal volume definition, the logical volume could have data allocated from any of the disks in the
volume group. The
vgdisk[index] keyword may be used for this purpose as well. Also applies to
VxVM volumes.
minor_number = number
Determines the logical volume number that is assigned to the associated logical volume which in
turn determines the minor number value for the device file. number may range from 0 to 255. If
the minor_number is not specified and the logical volume name is specified and is the form
lvolX, then the value X is used to determine the minor number. Otherwise, the value is assigned
in the order the volumes are created.
Volume Group Attributes
Volume groups may be either LVM or VxVM. Support for these two types of volume groups is release-
dependent.
usage = LVM
usage = VxVM
Determines type of volume group; the default is LVM.
Within the
volume_group block, the following LVM attributes may be set. See vgcreate (1M) for
details on meanings and defaults. These attributes are ignored for VxVM volume groups.
