NOF API Verbs
QUERY_LU_POOL
AP_DETAIL
Detailed information (list individual LUs in LU pools).
Combine this value using a logical OR operation with one of the following values:
AP_FIRST_IN_LIST
Start at the first entry in the list.
AP_LIST_INCLUSIVE
Start at the entry specified by the combination of the pool_name and lu_name parameters.
AP_LIST_FROM_NEXT
Start at the entry immediately following the entry specified by the combination of the pool_name and
lu_name parameters.
The list is ordered by pool_name and then by lu_name. For more information about how the list is ordered
and how the application can obtain specific entries from it, see Section 2.7, List Options For QUERY_* Verbs.
pool_name
Name of LU pool. This value is ignored if list_options is set to AP_FIRST_IN_LIST. This is an 8-byte
EBCDIC type-A string, padded on the right with spaces if the name is shorter than 8 characters.
lu_name
LU name. This value is ignored if list_options is set to AP_FIRST_IN_LIST or AP_SUMMARY. This is an
8-byte type-A EBCDIC string, padded on the right with spaces if the name is shorter than 8 characters.
To obtain information about all LUs in a pool, set pool_name to the name of the pool, set num_entries to 0,
and set lu_name to 8 binary zeros.
3.133.3 Returned Parameters: Successful Execution
If the verb executes successfully, SNAplus2 returns the following parameters:
primary_rc
AP_OK
buf_size
Length of the information returned in the supplied buffer.
total_buf_size
Returned value indicating the size of buffer that would have been required to return all the list information
requested. A value greater than buf_size indicates that not all the available entries were returned.
num_entries
Number of entries returned in the data buffer.
total_num_entries
Total number of entries available. A value greater than num_entries indicates that not all the available entries
were returned.
Each entry in the data buffer consists of the following parameters:
lu_pool_summary.overlay_size
The size of the returned
lu_pool_summary structure, and therefore the offset to the start of the next entry in the
data buffer.
When your application needs to go through the returned buffer to find each
lu_pool_summary structure in turn, it
must use this value to move to the correct offset for the next data structure, and must not use the C sizeof()
