OSSCACHING { ON | OFF }
specifies whether caching for Open System Services (OSS) files is ON or OFF.
The default is ON.
PHYSVOLSELECT { ON | OFF }
specifies whether a virtual disk process can consider this physical volume for file
placement. This attribute is valid only when this physical volume is a member of a
storage pool.
POOL { $pool | EXCLUDE }
specifies whether a physical volume is a member of a specified storage pool.
PROGRAM [[$vol.]subvol.]fileid
is the object file name of the IOP. If not specified, PROGRAM is:

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.

is the type of protection to use for the disk volume directory:
REVIVEBLOCKS number
is the number of revive blocks to be copied during each copy interval when the disk
is being revived. This value cannot exceed the maximum transfer size allowed by
the controller that is reviving the disk. number is in the range 1 through 292. The
default is 1.
ON A virtual disk process can consider this physical volume for file
placement (default).
OFF A virtual disk process cannot consider this physical volume for file
placement, regardless of the information supplied in a command.
If PHYSVOLSELECT is OFF, the value of AUTOSELECT
(page 14-77) is ignored.
$pool Adds the physical volume to the specified storage pool.
EXCLUDE Removes a disk from a storage pool.
CHECKPOINT Use a full-block checkpoint to protect directory writes.
OFF Do not perform special write protection of the directory.
SERIAL A write to the directory also results in a serial write to the
mirror disk, if available. If the mirror disk is not available, a
full-block checkpoint writes the directory. (Default)
