HP StorageWorks P9000 Data Exchange User Guide (T1620-96016, September 2010)

BL>32760

For the following dataset attributes, the data transfer is invalid if user does not specify the VSE

parameter value between RL and BL values shown in #1 and #2.

RL 32756

BL 32760

RL=BL

# 1: RL (input value for VSE parameter) = RL (value on VTOC) + 4 32756

# 2: BL (input value for VSE parameter) = BL (value on VTOC) + 8 32760

It is possible to transfer data between the correct dataset attributes (5 RL BL 4). The data transfer

is invalid if the VSE parameter is not the following value:

RL (input value for VSE parameter) = RL (value on VTOC) + 4 32756

BL (input value for VSE parameter) = BL (value on VTOC) + 8 32760

It is possible to transfer data between the correct dataset attributes (BL=RL+4 32760). The data

transfer is invalid if the RL and BL values on VTOC do not match to the following condition:

BL=RL+4 32760

In case RL and BL values on VTOC are RL > 32756 and BL > 32760, Data Exchange manages the

data as RL=32756 and BL=32760.

In case RL and BL values on VTOC are RL 32756, BL 32760, and RL = BL, Data Exchange

manage the data as shown below:

RL (Data Exchange internal value) = RL (value on VTOC) + 4 32756

BL (Data Exchange internal value) = BL (value on VTOC) + 8 32760

It is possible to transfer data between the correct dataset attributes (BL=RL+4 32760). The data

transfer is invalid if RL and BL values on VTOC do not match to the following condition:

BL=RL+4 32760

In case RL and BL values on VTOC are RL=BL 32752, Data Exchange manages the data as follows:

RL (Data Exchange internal value) = RL (value on VTOC) + 4

BL (Data Exchange internal value) = BL (value on VTOC) + 8

NOTE:

If you create a user program by using the dataset attribute exchange rule, you need to use the following

functions:

datasetGetFileInformation()

datasetGetFileInformationEx()
