Message

Comment or explanation (if not self-explanatory)

Cannot create array.

The controller either has no unassigned physical drives, or it already

has the maximum number of arrays or logical drives.

Cannot create logical drive.

There is no free space on the array, or the maximum number of

logical drives has already been reached.

Cannot expand array.

The controller does not support expansion, or the current

configuration of the controller does not allow expansion.

Cannot extend logical drive.

The controller does not support extension, or the current

configuration does not allow extension. For example, if there is no

free space on an array, extension is not supported.

Cannot migrate logical drive

RAID.

The controller does not support RAID migration, or the current

configuration of the controller does not allow migration.

Cannot migrate logical drive stripe

size.

The controller does not support stripe size migration, or the current

configuration of the controller does not allow migration.

Cannot remove physical drives

from existing array.

You have inadvertently omitted one or more physical drives from the

drive list when reconfiguring an existing array. ACU does not allow

this because removing physical drives from a configured array

causes data loss.

Controller (

text

) is invalid.

The controller specifications are not entered correctly.

ChassisName.

—

Controller does not support

controller SSPState. Use the

LogicalDriveSSPState command to

set SSP states for each logical

drive.

—

Controller does not support license

keys.

—

Controller does not support logical

drive SSP states. Use the SSPState

command to set the controller SSP

state.

—

Controller does not support

redundancy settings.

The controller is not redundant or does not support redundancy

settings.

Controller does not support SSP.

—

Controller has maximum number

of license keys.

—

Controller is locked by another

machine or user.

—

Controller requires non-failed

physical drives to set license keys.

—

Controller requires physical drives

to set license keys.
