Setting Default Values for vxassist
The default values that the vxassist command uses may be specified in the file
/etc/default/vxassist. The defaults listed in this file take effect if you do not
override them on the command line, or in an alternate defaults file that you specify using
the -d option. A default value specified on the command line always takes precedence.
vxassist also has a set of built-in defaults that it uses if it cannot find a value defined
elsewhere.
Note You must create the /etc/default directory and the vxassist default file if
these do not already exist on your system.
The format of entries in a defaults file is a list of attribute-value pairs separated by new
lines. These attribute-value pairs are the same as those specified as options on the
vxassist command line. Refer to the vxassist(1M) manual page for details.
To display the default attributes held in the file /etc/default/vxassist, use the
following form of the vxassist command:
# vxassist help showattrs
The following is a sample vxassist defaults file:
# By default:
# create unmirrored, unstriped volumes
# allow allocations to span drives
# with RAID-5 create a log, with mirroring don’t create a log
# align allocations on cylinder boundaries
layout=nomirror,nostripe,span,nocontig,raid5log,noregionlog,
diskalign
# use the fsgen usage type, except when creating RAID-5 volumes
usetype=fsgen
# allow only root access to a volume
mode=u=rw,g=,o=
user=root
group=root
# when mirroring, create two mirrors
nmirror=2
# for regular striping, by default create between 2 and 8 stripe
# columns
max_nstripe=8
min_nstripe=2
# for RAID-5, by default create between 3 and 8 stripe columns
max_nraid5stripe=8
min_nraid5stripe=3
