ALTER PROFILE Command
NAMEMASK { STANDARD | name }
specifies a naming convention for automatically configuring disks.
NONAUDITEDINSERT { ON | OFF }
(magnetic disks) specifies whether nonaudited insert mode is enabled (ON) or
disabled (OFF).
NUMDISKPROCESSES number
is the number of disk processes allocated for the disk. number is in the range 1
through 8. The default is 4.
Specifying fewer than 4 disk processes conserves memory but could decrease
system performance. Specifying more than 4 disk processes requires more
memory but could improve performance. The effect on your system depends on
your applications and the disk traffic they create.
STANDARD The disk is named using the standard manufacturing naming
convention (default). The name format is $Dggss, where gg is
the group number and ss is the slot number. For example, a
disk inserted in group 31, slot 12 is named $D3112.
For M8xxx Fibre Channel disks, the standard name format is
$FCnn, where nn is supplied by the storage subsystem. nn
begins in the range 00 through 99 and continues with A0
through ZZ.
If MIRRORING is ON, the name is created when the first disk is
inserted, and the same name is used when the second disk
inserted for the mirrored volume.
name The disk is named using a nonstandard naming convention.
name can have up to 4 characters. The name format is
$namenn, where nn is supplied by the storage subsystem. nn
begins in the range 00 through 99 and continues with A0
through ZZ. For example, NAMEMASK DATA specifies the
naming convention $DATA00, $DATA01, and so on.
ON enhances performance by buffering insertions to entry-sequenced
files or relative-sequenced files that do not have the REFRESH
attribute set and are open with a SYNCDEPTH greater than 0. This
feature is known as nonaudited insert mode.
However, the resulting reduction in the frequency of label updates
potentially increases the probability of data loss in the event of a
double disk failure.
OFF Nonaudited insert mode is disabled. This forces write inserts, which
increases EOF (default).
