SCF Storage Subsystem (Online Disk Remirroring)
(G06.21)
Upon receipt of the SPOOLER DRAIN command, the supervisor stops accepting jobs
for collection or printing (new opens are rejected with a file-system error 66—device
downed). Each collector stops when it has no more open jobs. Each print process
finishes printing any active jobs and then stops.
After all collectors and print processes have stopped, the supervisor process stops
itself. The spooler enters the dormant state, ready to be warm started.
An example of backing up the spooler control files:
BACKUP/OUTSPLBKUP/$TAPE,($SYSTEM.SPOOLER.*,$DATA01.SPOOLER.DATA),LISTALL
See Support Notes S97057 (T9101D41 Spooler Collector Data Files Have Changed
Format) and S99086 (NSK Spooler—Migration and Draining Instructions) for more
information.
CSPOOL Set at HIGHPIN
Beginning with G06.19, a new Spooler SPR T9101D48^AEY is introduced. This PVU is
installed by DSM/SCM with CSPOOL at HIGHPIN. If you do not want this setting, you
can change CSPOOL to use LOWPIN by issuing the BINDER command:
CHANGE HIGHPIN OFF IN CSPOOL
SCF Storage Subsystem (Online Disk Remirroring) (G06.21)
OSM automatically recognizes online remirrored disks (ODR). However, if you use
TSM, special steps are required before TSM can recognize online remirrored disks.
Online reconfiguration of a mirror drive cannot be performed while TSM ($ZTSM) is
running. Therefore, you must always stop the TSM server process before you
implement online disk remirroring. After issuing SCF commands for online disk
remirroring, 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.
Detailed syntax and explanations for using SCF commands to configure ODR are
documented in the SCF Reference Manual for the Storage Subsystem.
Note. DSM/SCM automatically sets CSPOOL to HIGHPIN. DSM/SCM automatically overlays
the current object file CSPOOL with the original from the SUT whenever a subsequent
Build/Apply is performed. See Support Note S03006A.
