To create a volume with a traditional DRL log by using the vxassist command

• Type the following command:

  # vxassist -g diskgroup make volume length mirror=2 \
    logtype=drl [loglen=len-blocks] [logmap_len=len-bytes]

  This command creates log subdisks that are each equal to the size of the DRL log.

  Note the following restrictions

  If neither logmap_len nor loglen is specified	loglen is set to a default value that is based on disk group alignment. maplen is set to a reasonable value.
  If only loglen is specified	For pre-version 110 disk groups, maplen is set to zero. For version 110 and greater disk groups, maplen is set to use all the bytes available in the on-disk map.
  If only logmap_len is specified	For pre-version 110 disk groups, logmap_len is not applicable. For version 110 and greater disk groups, maplen must be less than the number of available bytes in the on-disk map for the default log length.
