Use the SYNCMDRS comm<strong>and</strong> to retrieve Miscellaneous Data Records (MDRs)<br />

from specified devices. MDRs contain error <strong>and</strong> usage data from buffered control<br />

units or communications controllers. The records are logged in the <strong>VM</strong> error<br />

recording area.<br />

DASD<br />

will capture all MDRs for all DASDs.<br />

TAPE<br />

will capture all MDRs for 3480, 3490, <strong>and</strong> 3590 tape devices.<br />

PRINTER<br />

will capture all MDRs for all 3800 printer devices.<br />

ALL<br />

will capture all MDRs for all devices. If no oper<strong>and</strong> is specified, ALL is the<br />

default.<br />

1. Events that trigger automatic retrieval of MDRs usually occur infrequently. Some<br />

of these events are:<br />

v overflow of statistical counters in a buffered control unit<br />

v DASD volume demounts<br />

v VARY OFFLINE comm<strong>and</strong>s.<br />

The SYNCMDRS comm<strong>and</strong> lets you retrieve MDR records more frequently.<br />
