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.
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.
See the vxassist(1M) manual page.
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 # by default, create 1 log copy for both mirroring and RAID-5 volumes nregionlog=1 nraid5log=1 # by default, limit mirroring log lengths to 32Kbytes max_regionloglen=32k # use 64K as the default stripe unit size for regular volumes stripe_stwid=64k # use 16K as the default stripe unit size for RAID-5 volumes raid5_stwid=16k
