SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

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.
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
name
range 00 through 99 and continues with A0 through ZZ. For example, NAMEMASK DATA specifies
the naming convention $DATA00, $DATA01, and so on.
NEWENCRYPTKEY
sets a new encryption key on a disk.
If the disk is not encrypted, it is initialized as encrypted. If the disk is already encrypted, this
attribute changes the encryption key for a disk (single drive) while that drive is DOWN. Its
mirror may be UP. The disk volume will be online if the mirror is UP. The drive’s volume label
is left blank. If data needs to be copied from the other mirror, you must start the REVIVE manually
after the INITIALIZE command.
You must specify a path.
NOTE:
• This attribute is not valid for the ADD DISK command and the PROFILE object.
• Only members of the SAFEGUARD security officer group on the local system can perform
an ALTER DISK command with the NEWENCRYPTKEY attribute. Also, only security officers
can initiate a revive from an encrypted disk to a non-encrypted disk.
NONAUDITEDINSERT { ON | OFF }
(physical disks) specifies whether nonaudited insert mode is enabled (ON) or disabled (OFF)
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
ON
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.
disables nonaudited insert mode (default). This option forces write inserts, which increase EOF.OFF
NOSTART
specifies that the mirror disk should not be started for online disk reconfiguration with the ALTER
DISK command. To start the mirrored disk half, use the START DISK command.
NOTE: This attribute is not valid for the ADD DISK command and the PROFILE object.
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.
You can increase the value of this attribute while the disk is in the STARTED state. However,
to decrease the value of this attribute, the disk must be in the STOPPED state. As a result, this
attribute value cannot be decreased for the system disk unless you load the system from a saved
system configuration database that contains a smaller value for this attribute.
OSSCACHING { ON | OFF }
specifies whether caching for Open System Services (OSS) files is ON or OFF. The default is
ON.
