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
