Wild-card characters are supported.
OUT file-spec
directs all SCF output to the specified file.
POOL $pool
is the storage pool process.
LIKE object
identifies an existing object whose attribute values are copied to the object affected by this
command. The object name must currently exist in the system configuration, and the object
type must match that of the object affected by this command. If you specify LIKE, any attribute
values that you explicitly specify override the attribute values of the LIKE object.
attribute-spec
is one or more “ALTER POOL Attributes”.
ALTER POOL Attributes
[ , AUDITED { ALLOWED | DISALLOWED | REQUIRED } ]
[ , BACKUPCPU number ]
[ , DISKINTERVAL number ]
[ , DISKTHRESHOLD number ]
[ , EXTENTINTERVAL number ]
[ , EXTENTTHRESHOLD number ]
[ , HIGHPIN { ON | OFF } ]

[ , STARTSTATE { STARTED | STOPPED } ]
[ , UPDATESTATS number ]
AUDITED { ALLOWED | DISALLOWED | REQUIRED }
is the type of volume you can add to the storage pool.
You can add any volume, even if it is not protected by TMF (default).ALLOWED
You can add a volume only if it is not protected by TMF.DISALLOWED
You can add a volume only if it is protected by TMF.REQUIRED
BACKUPCPU number
is the processor in which the backup IOP starts. The process must be in the STOPPED state or
not running for you to alter this attribute.
DISKINTERVAL number
is the interval (as a percentage) that, with the DISKTHRESHOLD attribute, is used by the disk
process to determine when to issue a disk-full EMS message for physical volumes in the storage
pool. For example, if DISKTHRESHOLD is 70 and DISKINTERVAL is 5, the disk process issues
an EMS message when the disk becomes 70, 75, 80, 85, 90, and 95 percent full.
number is either -1 (the default, no disk-full EMS messages are issued) or in the range 1 through
99 percent.
This attribute has no effect if DISKTHRESHOLD is -1.
