Veritas Storage Foundation Portable Data Containers: Cross-Platform Data Sharing 5.0.1 Administrators Guide, HP-UX 11i v3, First Edition, November 2009

Utilities such as vxprint and vxdg list that print information about disk
group records also output the disk group alignment.
Displaying the log map length and alignment
To display the log map length and alignment
■ Type the following command:
# vxprint [ -g diskgroup ] -lv volume
For example, to print information for the volume vol1 in disk group dg1:
# vxprint -g dg1 -lv vol1
The output is of the form:
logging: type=REGION loglen=0 serial=0/0 mapalign=0
maplen=0 (disabled)
This indicates a log map alignment (logmap_align) value of 0, and a log map
length (logmap_len) value of 0.
If the log map is set and enabled, the command and results may be in the
following form:
# vxprint -lv drlvol
Disk group: dgTestSol
Volume: drlvol
info: len=20480
