GSVOL report

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

Report output

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.

Monitoring information

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).
