ADD POOL Command
If you specify PROGRAM as $SYSTEM.SYSTEM, the operating system first
searches for the file on $SYSTEM.SYSTEM and on the current SYSnn
subvolume.
STARTSTATE { STARTED | STOPPED }
specifies whether the IOP is available to other processes (STARTED) or
unavailable (STOPPED) when the system is loaded or reloaded. The default is
STARTED.
UPDATESTATS number
is the interval (in minutes) at which the storage pool process should collect
information about the physical volumes in the storage pool. number is either -1
(no statistics should collected) or in the range 0 through 1440. The default is 30.
If you specify a very large number, statistics are gathered infrequently. Depending
on how much virtual disk activity occurs, virtual disk processes could make
volume-selection decisions using out-of-date information.
Specifying a small value for number results in statistics being gathered frequently
but might affect system performance.
