Claim 17:
18. Data storage equipment, comprising:
a first storage processor enclosure;
a second storage processor enclosure; and
electronic circuitry coupled with the first storage processor enclosure and the second storage processor enclosure, the electronic circuitry including memory and control circuitry coupled with the memory, the memory storing instructions which, when carried out by the control circuitry, causing the control circuitry to perform a method of:
providing, to a set of external host computers, access to data stored in a plurality of storage devices while each storage device of the plurality of storage devices resides in the first storage processor enclosure,
providing, to the set of external host computers, access to the data stored in the plurality of storage devices while the plurality of storage devices is moved from the first storage processor enclosure to the second storage processor enclosure, and
providing, to the set of external host computers, access to the data stored in the plurality of storage devices while each storage device of the plurality of storage devices resides in the second storage processor enclosure;

wherein providing access to the data while the plurality of storage devices is moved from the first storage processor enclosure to the second storage processor enclosure includes:
within a predefined storage device failure time limit, losing communication with a particular storage device of the plurality of storage devices when the particular storage device is removed from the first storage processor enclosure and regaining communication with the particular storage device when the particular storage device is installed into the second storage processor enclosure to prevent initiation of a rebuild procedure configured to rebuild the particular storage device.
