RMF PPRC Link -path Statistical Information Support
When you use z/OS Resource Measurement Facility (RMF), and if you specify
the IBM TotalStorage Enterprise Storage Server
®
(ESS), you can acquire the
PPRC Fibre Link-path statistical information. For further information on the
PPRC Link-path statistical information acquisition, please refer to the IBM
publications.
Table 2-13and Table 2-14 give the USP V adaptor ID (SAID) values for the
LINK parameters (ports) that are displayed when you acquire the PPRC Link-
path statistical information using RMF.
Note: The USP V adaptor ID (SAID) values in Table 2-13 and Table 2-14 are
different from the ones for the LINK parameters of CESTPATH TSO commands
(see Table 2-11, Table 2-12, Table A-2 ).
Note: If you acquire the PPRC Fibre Link-path statistical information by using
RMF, and if the total data size per the interval for which you acquire the data
is 100 kB and below, zero may be reported for the data size. Even if the data
is not updated by host I/O during TCzA operations, the data size is reported.
This is because the recordset which does not have data is sent from MCU to
RCU. In this case, if the total data size per the interval for which you acquire
the data is 100 kB and below, zero may also be reported for the data size.
