DISKINFO Procedure
(Superseded by FILE_GETINFOLISTBYNAME_
name input
INT .EXT:ref:12
is the name of the disk volume being inquired about. The name can be that of a
disk volume (blank padded), or of a disk file, or of a DEFINE designating a disk
volume or file. The name can refer to a disk on a different network node.
capacity output
INT(32) .EXT:ref:1
is the information capacity of the volume as labeled, in pages (2048 byte units).
This value accounts for the space taken up for data protection (spare sectors, and
so on), but does not account for space used by the operating system for volume
management (such as directory space) or other uses.
avail output
INT(32) .EXT:ref:1
is the total free space currently available, in pages (2048 byte units).
numfrag output
INT(32) .EXT:ref:1
is the number of individual free space fragments.
biggest output
INT(32) .EXT:ref:1
is the size, in pages, of the largest free space fragment.
drivekinds output
STRING .EXT:ref:16
identifies the kinds of drives on which the volume is mounted. The value contains
two fields of ASCII data:
[0:7] The product number of the primary drive
[8:15] The product number of the mirror drive
If information is unavailable for a drive (because it is inaccessible or not
configured), its corresponding field will be blank. Drive models 4110 and 4120,
which cannot be distinguished by software, are returned as “4110”. Similarly, drive
model 4106 is returned as “4105”, 4111 as “4110”, and 4115 as “4114”.
The last four characters of the product-number fields sometimes contain either
blanks or modifiers used to distinguish between different versions of a product.
Also, for the 4105 model, an “M” or “F” modifier refers to the moving-head part or
the fixed-head part of the drive.
