SCF Storage Subsystem (Online Disk Remirroring)
•
Use the SPOOLCOM;COLLECT $ collector-process , LISTOPENS command
to identify processes that currently have jobs open.
•
Use the SPOOLCOM;JOB (STATE PRINT) command to determine which jobs are
currently printing.
Verify that these jobs either terminate when finished or are stopped.
Before entering the DRAIN command, you should always back up the spooler control
files:
BACKUP/OUTSPLBKUP/$TAPE,($SYSTEM.SPOOLER.*,$DATA01.SPOOLER.DATA),LISTALL
For more information on proper shutdown of the spooler, see Support Notes S97057
(
T9101D41 Spooler Collector Data Files Have Changed Format ) and S99086 ( NSK
Spooler—Migration and Draining Instructions
).
CSPOOL Set at HIGHPIN
Beginning with G06.19, a new spooler SPR, T9101D48^AEY, is introduced. This SPR
is installed by DSM/SCM with CSPOOL at HIGHPIN. If you do not want this setting,
you can change CSPOOL to use LOWPIN by issuing the BINDER command:
CHANGE HIGHPIN OFF IN CSPOOL
SCF Storage Subsystem (Online Disk Remirroring)
Beginning with G06.21, OSM automatically recognizes online remirrored disks.
However, you cannot perform online reconfiguration of a mirror drive while TSM
($ZTSM) is running. You must always stop the TSM server process before you
implement online disk remirroring (ODR). After issuing SCF commands for ODR,
restart the TSM server.
During the ODR operation when using TSM, error 00012 might appear. For cause and
recovery information, see Appendix B in the
SCF Reference Manual for the Storage
Subsystem
.
For detailed descriptions of using SCF commands to configure ODR, see the
SCF
Reference Manual for the Storage Subsystem
.
Caution. To maintain the integrity of the spooler environment, wait until the spooler has
finished draining rather than stop spooler processes by using the TACL STOP command. The
control file can be corrupted during the next warm start or rebuild.
Note. DSM/SCM automatically sets CSPOOL to HIGHPIN and automatically overlays the
current object file CSPOOL with the original from the SUT whenever a subsequent Build/Apply
is performed. See Support Note S03006A.
