4096, and 8192; the default is 1024.

fragsize = number

Sets the ﬁle system fragment size to number.

ncpg = number

Sets the number of cylinders per group to number.

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 logical 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.
