Setting Nonvolatile Storage On for the Subsystem z/OS DFSMS Access Method Services Commands SC23-6846-01 |
|
SETCACHE NVS ON enables use of the nonvolatile storage for the subsystem and connects the battery to the NVS. If the command fails, it may be due to:
If the probable cause is pinned data, use LISTDATA PINNED SUBSYSTEM or DEVSERV to identify which volumes in the subsystem have pinned data. Fix the problem that is preventing destage, if possible. If the volume cannot be repaired, use DASD installation recovery procedures. If the pinned volumes have DASD fast write active, issue DASDFASTWRITE OFF and then DASDFASTWRITE PENDINGOFF to clear the pinned tracks and set DASD fast write off. DISCARDPINNED can also be used; follow DASD recovery procedures. If the probable cause is NVS failed or disabled, fix the problem and reissue SETCACHE NVS ON. |
