HPVOLINFO
error.
-183* Disk access error. Check the error stack to determine the
exact error.
-184* A mirrored volume that was specified is disabled.
-185* The volume set specified is not a volume set on the system.
-186* The volume class specified is not present in the volume set
specified.
-187* The member volume specified is not present in the volume
set specified.
volspecifiernum 16-bit signed integer by value (optional)
A 16-bit integer indicating which volume specifier is to be used to obtain
information from HPVOLINFO. The default value for
volspecifiernum is 0
(zero) if it is not included by the caller. This parameter is used in
conjunction with the
volspecifier parameter.
The following are the valid volume specifier numbers:
Value Meaning
0 Volume specifier is ignored. Using 0 (zero) is the same as
specifying all the volumes on the system.
1 Volumespecifier is the logical device number of the volume
for which information is to be obtained.
2 Volume specifier is a volume set name.
3 Volume specifier is a volume set/volume class name pair.
4 Volume specifier is a volume set/volume name pair.
5 Volume specifier is a device class name.
volspecifier Type varies (optional).
The
volspecifier is optional when volspecifiernum is 0 (zero).
However, for a
volspecifiernum of 1, 2, 3, 4, or 5, you must specify a
volspecifier parameter.
On MPE V, you must declare
volspecifier as a byte array.
The data type of the
volspecifier depends on the volspecifiernum :
volspecifiernum volspecifier
0
Ignored
1 16-bit signed integer
2, 3, 4, 5 Character array
When 0 (zero) is used as the
volspecifiernum , the volspecifier is
ignored. A
volspecifiernum of 0 (zero) refers to all the volumes on the
system. This includes all system and nonsystem volumes.
