- Wsid
An eight-character input byte array.
The Wsid parameter identifies your workstation. It must contain a
left-justified alphanumeric name beginning with a letter. If the
workstation identifier is less than eight characters long, it must
be followed by blanks.
- MaxEntries
An input integer. The
MaxEntries parameter contains the maximum number of entries expected
in all output array parameters except Result. The MaxEntries parameter value should be the number of LUs configured
for the workstation, from 1 through 16.
Make sure that the available length of each of the output array
parameters (LUList, ChainSizeList, MinJobSizeList, MaxJobSizeList, ActiveLUNumList, and AutoStartList) is sufficient for the expected number of entries.
- ReturnEntries
An output integer. The
ReturnEntries parameter normally contains the actual number of entries
in all output array parameters except Result.
After calling NRJELUList, ReturnEntries can contain the required number of entries for LUList, ChainSizeList, MinJobSizeList, MaxJobSizeList, ActiveLUNumList, and AutoStartList. This occurs only when the first word of Result is 137, which means that MaxEntries was too small.
- LUList
An output byte array. The
LUList array contains a list of entries of all LU names for
the workstation. Each entry is eight characters, left-justified,
with trailing blanks. Following is an example of a three-entry
LUList:
- ChainSizeList
An output integer array.
The ChainSizeList array contains a list of chain sizes for each LU in
a workstation.
A chain size is the number of RUs sent from the workstation
to the host before requesting a positive response.
- MinJobSizeList
An output double-word integer array.
This parameter is hardcoded to return 0.
- MaxJobSizeList
An output double-word integer array.
This parameter is hardcoded to return a maximum sector size of 2147483647.
- ActiveLUNumList
An output integer array.
The ActiveLUNumList array contains a list of active LU numbers. A zero
entry indicates an LU is inactive. An active entry is a positive integer,
which is the LU number.
Following is a three-entry ActiveLUNumList corresponding to LUList, above:
0 ERST is inactive.
34 NEXTONE is active, and its LU number is 34.
22 LAST is active, and its LU number is 22.
- AutoStartList
An output integer array.
The AutoStartList array contains a list of flags of LUs that are automatically initiated.
Automatic starting is a configurable item.
A zero element is returned if an LU is not initially started
when a workstation is started.
A -1 element is returned if an LU is initially started.
following is a three-entry AutoStartList corresponding to LUList, above:
0 ERST is not initially started.
-1 NEXTONE is initially started.
-1 LAST is initially started.
- Result
An eight-element integer output array
(required). The Result array contains error codes that occurred during execution
of this intrinsic.
The first element of the Result array is set to zero if no errors took place. The structure
of the Result array is described in "Parameters Common to
NRJE Intrinsics" in the introduction to this chapter.
Always test the first element of Result immediately after you call this intrinsic. If the first
element of Result is not zero, test the other elements of Result to determine the nature of the problem that has occurred.
