When available space goes below a predetermined critical threshold, the error is displayed, along with the associated event code:
085081 Array storage is critically low on available physical space
The array is automatically write-protected when the error is displayed; no further data can be written to the array until the situation is corrected.
The exact value of the critical threshold is not user-configurable, and is subject to change.
Use the rmvdisk command to delete unwanted volumes.
Space is not immediately available after you remove a volume. To reclaim the space, run the recoverarray -trim command. This command might impact performance.
