Device Activity - SMF record type 74-1

One qualifier is required, otherwise a syntax error occurs and RMF™ will not process the condition.

devnmbr: A one- to four-digit hexadecimal device number in the range 0000 through FFFF. Example: (012F)
volser: A one- to six-character volume serial number enclosed in quotes. Example: ('012345')
stg grp: A one- to eight-character storage group name in parentheses, preceded by the keyword SG. Example: (SG(COMMON01))
class: Any of the six valid device classes for Monitor I device activity measurements.

For OVW statements, only the qualifiers devnmbr and volser are valid. If you have selected a shared device in the sysplex, you will receive a value which reflects the sysplex view (not possible for DNOTRDY, DHPAVNM, DHPAVLSS, and DVCAP).

All times reported are in milliseconds, unless otherwise noted.
