Displaying Profile Attributes
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 and M8xxx disks only) specifies whether the disk
process is automatically started when 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
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). When ON, FSTCaching 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 (the
default), DISABLED, or FORCED. For mirrored volumes,
see also SerialWrites on page 5-13.
HaltOnError
shows whether an internally detected disk-process failure
should force a halt (code%11500) in the primary processor,
backup processor, or both.
HighPin
the PIN range available to the disk process.
LKIDLongPoolLen
the memory (in 128-KB units) to be allocated for lock key
space. This space is used to store keys larger than 16 bytes
when locking records in key-sequenced files.
LKTableSpaceLen
the memory (in 128-kilobyte units) to be allocated for lock-
related data structures. The memory available for these
structures limits the total file and record locks allowed on the
disk.
MaxLocksPerOCB
the maximum number of records which can be locked
outside a transaction.
MaxLocksPerTCB
the maximum number of records and files a transaction can
lock.
Mirroring
shows whether the storage subsystem manager process
should assign a mirror disk for an inserted internal disk.
NameMask
the naming mask used when auto-assigning a process
name for a disk volume. The default value (STANDARD) is
the factory naming convention.
NumDiskProcesses
the number of disk processes allocated for the disk.
