Disk Type Specific Information
AuditTrailBuffer/
SQLMXBuffer (MB)
shows one of:
•
The audit-trail buffer size in megabytes for a TMF audit-
trail volume. This value is used to improve the
performance of systems using the Remote Duplicate
Database Facility.
•
The SQLMXBuffer attribute specifies the buffer size (in
megabytes) for an SQL/MX session in DP2.
AutoRevive shows whether the storage subsystem manager automatically
starts a revive operation on an internal SCSI or M8xxx disk
that is inserted into a slot.
AutoSelect (magnetic disks only) shows whether a virtual disk process is
allowed to automatically consider this physical volume when
making file placement decisions.
AutoStart (internal SCSI and M8xxx disks only) specifies whether the
disk process is automatically started when the disk is inserted.
CBPoolLen the maximum memory (in 128-KB units) that can be allocated
for open-related data structures on the disk. The memory
available for these structures limits the total number of
concurrent opens allowed on the disk.
FSTCaching shows whether the free space table for a disk is updated in
memory (ON) or on disk (OFF). FSTCaching ON can increase
performance. The FST is always rebuilt from disk when the
disk is started. The system disk always runs with
FSTCACHING ON, regardless of the configured value.
FullCheckpoints shows whether the validity of data written to the disk is being
protected by a full-block checkpoint (applies only to
nondirectory structured files). Options are ENABLED,
DISABLED, or FORCED. For mirrored volumes, see
SerialWrites on page 5-7.
HaltOnError shows whether an internally detected disk-process failure
should force a halt (code %11500) in the primary processor,
backup processor, or both.
LKIDLongPoolLen the memory (in 128-KB units) to be allocated for lock key
space. This space stores keys larger than 16 bytes when
locking records in key-sequenced files.
