3990). GDPS support may have additional installation requirements for the
XP1024/XP128/XP12000/XP10000 TC390 MCUs and RCUs, depending on
XP1024/XP128/XP12000/XP10000 microcode levels and Command View XP or XP Remote Web
Console software versions. Check the following items with your HP representative:
• SVP modes. For operations in a GDPS environment:
Mode 64 must be OFF.
Mode 104 must be ON for 3990 controller emulation (not valid for 2105 emulation).
For more information on XP1024/XP128/XP12000/XP10000 SVP modes related to TC390
operations, refer to Table 4
on page 20.
Mode 104 must be set before any TC390 pairs are established in a GDPS environment. If TC390 pairs
have already been established, you must delete all pairs and logical paths (CDELPAIR, CDELPATH),
change the SSIDs and mode settings on the MCUs and RCUs, and then re-establish the paths and pairs
(CESTPATH, CESTPAIR). Installation of mode 64 is nondisruptive and can be performed at any time.
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 13 and Table 14 give the XP1024/XP128/XP12000/XP10000 USP system 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 XP1024/XP128/XP12000/XP10000 USP system adaptor ID(SAID) values in Table 13 and
Table 14 are different from the ones for the LINK parameters of
TSO commands (see Tab le 34 and Table 35).
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.
