SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

PRIMARYCPU number
is the processor in which the primary IOP starts. The process must be in the STOPPED state or
not running for you to alter this attribute.
PROGRAM [[$vol.]subvol.]fileid
is the object file name of the IOP. If not specified, PROGRAM is:
$SYSTEM.SYSTEM.OPP
If you specify the program file name location as $SYSTEM.SYSTEM, the operating system first
searches for the file there 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using out-of-date information.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.
ALTER POOL Examples
See the procedure for “Altering Storage Pool Attribute Values” (page 139).
• To change when a pool process provides disk-full information:
-> ALTER $POOL01, DISKINTERVAL 10, DISKTHRESHOLD 80
• To change how often a pool process collects information about physical volumes in the pool:
-> ALTER $POOL00, UPDATESTATS 3
ALTER PROFILE Command
The ALTER PROFILE command changes a disk configuration profile. The syntax is:
ALTER [ / OUT file-spec / ]
PROFILE $ZZSTO.INTERNAL-DISK[-groupnum ]
[ , attribute-spec ]...
Wild-card characters are supported.
OUT file-spec directs all SCF output to the specified file.
PROFILE $ZZSTO.INTERNAL-DISK [-groupnum ] is either the standard default profile,
$ZZSTO.#INTERNAL-DISK, or a user-created
custom profile for enclosure groupnum.
groupnum cannot have a leading zero.
attribute-spec is one or more “PROFILE Attributes”.
PROFILE Attributes
For a description of these attributes, see “Attribute Descriptions for Disk Commands” (page 198).
