SM2 reports

This report provides global monitored data on the individual 3419/21 controllers. One line
is output for each controller.

The REPORT PCA statement is used to request the output of the PCA CONTROLLER
report. The report can only be output if the SM2 administrator has activated the monitoring
process using the statement START-MEASUREMENT-PROGRAM TYPE=*PCA.
Overflow screens may also be requested for this report.
The monitored data output is sorted in accordance with the size of the cache (CACHE
SIZE).

The individual entries have the following meanings:

CTL DEV

Mnemonic name of the controller’s CONTROL DEVICE

CACHE SIZE

Amount of memory reserved for caching in MB

#CACH

Number of caches

#

PEND. BLOCKS

Number of blocks (2K/4K, depending on the disk format) still to be
relocated to disk

READ (1/S)

Total number of read operations to disks for which caching is
performed (in I/Os per second)

C-READ (1/S)

Total number of read operations to be executed as fast reads
(caching reads) (in I/Os per second)
