Explanation of Fields
Disk Type Specific Information
Shows one of:AuditTrailBuffer/
SQLMXBuffer (MB)
• 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.
Shows whether the storage subsystem manager automatically starts a revive operation on an
internal SCSI or M8xxx disk that is inserted into a slot.
AutoRevive
(Physical disks only) shows whether a virtual disk process is allowed to automatically consider
this physical volume when making file placement decisions.
AutoSelect
(Internal SCSI and M8xxx disks only) specifies whether the disk process is automatically
started when the disk is inserted.
AutoStart
Specifies whether the source drive remains up or goes harddown when a revive completes
for a mirrored volume consisting of drives of different capacities.
CapacityMismatch
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.
CBPoolLen
Shows whether Fast Cache Bulk Writes are turned on. When ON, applications and utilities
using bulk writes to unstructured files may have higher throughput. Using FastBulkWrite ON
FastBulkWrite
can result in lost data in unstructured files if the CPU running the primary disk process fails.
This attribute affects all 512-byte-sector disks.
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
FSTCaching
is started. The system disk always runs with FSTCACHING ON, regardless of the configured
value.
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.
FullCheckpoints
Shows whether an internally detected disk-process failure should force a halt (code %11500)
in the primary processor, backup processor, or both.
HaltOnError
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.
LKIDLongPoolLen
The memory (in 128-kilobyte units) to be allocated for lock-related data structures. The memory
available for these structures limits the total number of file and record locks allowed on the
disk.
LKTableSpaceLen
The maximum number of records that can be locked outside a transaction.MaxLocksPerOCB
The maximum number of records and files a transaction can lock.MaxLocksPerTCB
Indicates whether nonaudited insert mode is enabled.NonAuditedInsert
The number of disk processes allocated for the disk.NumDiskProcesses
Shows whether caching for HP NonStop Open System Services (OSS) files is enabled.OSSCaching
