Abstract
A technique of managing thin pool logical unit (TLU) recovery is performed in a data storage array that forms TLUs from a slice storage pool of logical unit (LUN) slices. The technique involves allocating a set of LUN slices of the slice storage pool to support TLU recovery. The technique further involves, after the set of LUN slices has been allocated, taking offline a TLU which currently requires TLU recovery. The technique further involves, while the TLU is offline, performing a TLU recovery procedure to recover the TLU. The TLU recovery procedure utilizes the set of LUN slices that was allocated to support TLU recovery.
