Parameter Description
repositoryLogicalDrive
The alphanumeric identifier of the repository logical
drive has the Enhanced FlashCopy image. All repository
identifiers have this form:
repos_xxxx
where xxxx represents a four digit numerical value.
Enclose the Enhanced FlashCopy logical drive name in
double quotation marks (" ").
repositoryFullLimit The percentage of repository capacity at which you
receive a warning that the Enhanced FlashCopy
repository logical drive is nearing full. Use integer
values. For example, a value of
70
means 70 percent. The
default value is 75 .
Notes
You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for
the names. Names can have a maximum of 30 characters.
The identifier of an Enhanced FlashCopy image has two parts separated by a colon (:):
v
The name of the Enhanced FlashCopy group
v
The identifier of the Enhanced FlashCopy image
For example, if you want to create an Enhanced FlashCopy logical drive named enhancedFlashCopyData1
using the most recent Enhanced FlashCopy image in an Enhanced FlashCopy group that has the name
enhancedFlashCopyGroup1
with a maximum fill limit of 80 percent for the repository logical drive, you
would use this command:
create enhancedFlashCopyLogicalDrive userLabel="enhancedFlashCopyData1"
enhancedFlashCopyImageID="enhancedFlashCopyGroup1:newest"
repositoryLogicalDrive="repos_1234" repositoryFullLimit=80;
The repository logical drive identifier 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.
Create FlashCopy Logical Drive
This command creates a FlashCopy logical drive of a base logical drive. You can also use this command
to create a new repository subsystem if one does not already exist, or if you would prefer a different
repository subsystem. This command defines three ways to create a FlashCopy logical drive:
v In a new repository subsystem created from user-defined drives
v
In a new repository subsystem created from a user-defined number of drives
v
In an existing repository subsystem
If you choose to define a number of disk drives, the controller firmware chooses which disk drives to use
for the FlashCopy logical drive.
Syntax (User-Defined Number of Drives)
create flashcopyLogicalDrive baseLogicalDrive="baseLogicalDriveName"
(repositoryRAIDLevel=(1 | 3 | 5 | 6) repositoryDrives=(enclosureID1,drawerID1,slotID1 ...
enclosureIDn,drawerIDn,slotIDn))
