SM2 reports

This report provides monitored data on emulated volumes in global storage.

The REPORT GSVOL statement is used to request the output of the GSVOL reports. This
report can only be output if the SM2 administrator has activated the monitoring process
using the statement START-MEASUREMENT-PROGRAM TYPE=*GSVOL.

Overflow screens may also be requested for this report.
The monitored data output is sorted under the categories READ and WRITE.

DEVICE-MN

Mnemonic device name of the emulated volume

UNIT

GS unit on which the volume was created
A dual partition consists of a contiguous address space on both GS
units, whose start addresses are differentiated by the HW constant
“DUPLICATION-BOUNDARY”.

READ (1/S)

Number of read I/O operations

WRITE (1/S)

Number of write I/O operations

When comparing with the values of the GS report, note that in the GSVOL report the I/O
operations refer to the emulated volumes. One I/O operation can hide several GS accesses
(additional key, block length).
