AUTOSELECT { ON | OFF }
specifies whether a virtual disk process is allowed to automatically consider this
physical volume when making file-placement decisions. This attribute is valid only
when this physical volume is a member of a storage pool.
AUTOSTART { ON | OFF }
(internal and M8xxx disks only) specifies whether to automatically start the disk
process when the disk is inserted.
DISK AUTOSTART ON is ignored if SUBSYS AUTOSTART is OFF.
For information about using this attribute, see Mirrored Disk Placement on

CBPOOLLEN number
is the maximum memory (in 128-KB units) that can be allocated for open-related
data structures for the disk. The memory available for these structures limits the
total number of concurrent opens allowed on the disk. number is in the range 0
through 1000. The default is 1000.
FSTCACHING { ON | OFF }
specifies that the free-space table (FST) for a disk is updated in memory (ON), that
the FST is updated on disk (OFF) or that DP2 decides whether to keep the FST in
memory or on disk (ENABLED). The default is OFF. FSTCACHING ON can
increase performance. The FST is always rebuilt from disk when the disk is
started.
The system disk always runs with FSTCACHING ON regardless of the configured
value.
ON Enable automatic selection (default).
OFF Disable automatic selection.
ON Enable automatic starting (default).
