armcopy
Description
The armcopy command manages the business copy feature of the array.
Syntax
armcopy -p <LUN> -s <LUN> [ -a { true | false } ] <array-id>
armcopy -s <LUN> { -x { true | false} | -a { true | false } } <array-id>
armcopy -r <LUN> <array-id>
armcopy -?
Options
-a {true|false} Controls the content of the busines copy.
When used with both the -p and -s options, a value of true creates a
business copy with content linked to the parent LUN data. A value of false
creates an empty business copy LUN. The business copy will be allocated
with the same capacity as the parent, but the content of the business copy
will not be linked to the parent LUN data. If this option is not included, the
default will be set to true.
When used with the –s option only, a true value copies data from the
parent LUN to the business copy. A false value empties the business
copy.
-p <LUN> Identifies the parent LUN to be copied. The LUN must exist and it may not
be a business copy.
-r <LUN> Copies the data on the business copy LUN back to the parent LUN.
This option will work only if there is a single business copy of the LUN. If
there are multiple business copies of the LUN, this command will fail.
-s <LUN> Identifies the LUN to be assigned or is assigned to the business copy.
-x { true | false } Activates (true) or deactivates (false) the specified business copy LUN.
Deactivating a LUN does not make the LUN data inaccessible. It indicates
that the LUN is less likely to be accessed than other, active, LUNs. This
helps the array to determine how best to manage its resources.
