Report output
The PCA DEVICE report is output only at the explicit request of the SM2 user with the help
of the SELECT-PCA-CACHE statement (see page 174). This statement is used to output a
PCA CONTROLLER report together with a PCA DEVICE report for the selected cache of
a controller. The PCA DEVICE report supplies detailed information on the devices of a
3419/21 controller which have been allocated a cache.
The report can only be output if the SM2 administrator has activated the monitoring process
using the statement START-MEASUREMENT-PROGRAM TYPE=*PCA.
