Parameter Description
UserLabel
The name that you want to give the FlashCopy logical
drive. Enclose the FlashCopy logical drive name in
double quotation marks (“ ”).
enclosureLossProtect
The setting to enforce enclosure loss protection when you
create the FlashCopy repository logical drive. To enforce
enclosure loss protection, set this parameter to
TRUE
. The
default value is
FALSE
.
drawerLossProtect
The setting to enforce drawer loss protection when you
create the mirror repository logical drive. To enforce
drawer loss protection, set this parameter to
TRUE
.The
default value is FALSE .
driveMediaType The type of drive medium that you want to use for the
mirror repository logical drive. Valid drive media are
these:
v HDD
– Use this option when you have hard drives in
the drive expansion enclosure.
v SSD
– Use this option when you have solid state drives
in the drive expansion enclosure.
v unknown
– Use if you are not sure what types of drive
media are in the drive expansion enclosure.
v allMedia – Use this option when you want to use all
types of drive media that are in the drive expansion
enclosure.
Use this parameter when you use the
repositoryDriveCount
parameter.
You must use this parameter when you have more than
one type of drive media in your storage subsystem.
DriveType
The type of disk drives that you want to use for the
FlashCopy repository logical drive. Valid disk drive
types are
SCSI
,
fibre
, or
SAS
.
freeCapacityArea
The index number of the free space in an existing
subsystem that you want to use to create the FlashCopy
repository logical drive. Free capacity is defined as the
free capacity between existing logical drives in an
subsystem. For example, an subsystem might have the
following areas: logical drive 1, free capacity, logical
drive 2, free capacity, logical drive 3, free capacity. To use
the free capacity following logical drive 2, you would
specify:
freeCapacityArea=2
Run the
show subsystem
command to determine if a free
capacity area exists.
warningThresholdPercent
The percentage of repository capacity at which you
receive a warning that the FlashCopy repository logical
drive is nearing full. Use integer values. For example, a
value of
70 means 70 percent. The default value is 50 .
repositoryPercentOfBase The size of the FlashCopy repository logical drive as a
percentage of the base logical drive. Use integer values.
For example, a value of
40
means 40 percent. The default
value is
20
.
