■ The value is constrained by size of
the log, and cannot exceed the size
of the on-disk map.Thesize of the
on-disk map in blocks can be
calculated from the following
formula:
round(loglen/nmaps) - 24
where nmaps is 2 for a private disk
group, or 33 for a shared disk group.
■ The value of logmap_len cannot
exceed the number of bytes in the
on-disk map.
If logmap_len is specified
■ Specifying a value that is less than
twice the disk group alignment
value results in an error message.
■ The value is constrained by size of
the logging subdisk.
If loglen is specified
