IBM System Storage DS3000, Programming Manual

Page: 279 / 652

Parameter Description
repositoryFullLimit
The percentage of repository logical drive capacity at
which you receive a warning that the Enhanced
FlashCopy image repository logical drive is nearing full.
Use integer values. For example, a value of
70
means 70
percent. The default value is
75
.
Notes
The repository logical drive name is automatically created by the storage management software and the
firmware when you create a new Enhanced FlashCopy group. You cannot rename the repository logical
drive because renaming the repository logical drive will break the linkage with the Enhanced FlashCopy
images.
Set Remote Mirror
This command defines the properties for a remote-mirror pair.
Syntax
set remoteMirror (localLogicalDrive [ logicalDrive ] |
localLogicalDrives [ logicalDriveName1 ... logicalDriveNameN ])
role=(primary | secondary)
[force=(TRUE | FALSE)]
syncPriority=(highest | high | medium | low | lowest)
autoResync=(enabled | disabled)
writeOrder=(preserved | notPreserved)
writeMode=(synchronous | asynchronous)
Parameters
Parameter Description
localLogicalDrive
or
localLogicalDrives
The name of the primary logical drive for which you
want to define properties. You can enter more than one
primary logical drive name. Enclose the primary logical
drive name in square brackets ([ ]). If the primary
logical drive name has special characters, you also must
enclose the primary logical drive name in double
quotation marks (“ ”).
role The setting for the logical drive to act as the primary
logical drive or the secondary logical drive. To define
the logical drive as the primary logical drive, set this
parameter to
primary
. To define the logical drive as the
secondary logical drive, set this parameter to
secondary
. This parameter applies only when the
logical drive is part of a mirror relationship.
force
The role reversal is forced if the communications link
between the storage subsystems is down and
promotion or demotion on the local side results in a
dual-primary condition or a dual-secondary condition.
To force a role reversal, set this parameter to
TRUE
. The
default value is FALSE .
syncPriority The priority that full synchronization has relative to
host I/O activity. Valid values are
highest
,
high
,
medium
,
low
, or
lowest
.
