(C) the handling manipulation is to recover a blocked pool for the storage apparatus, and the prerequisite manipulation is one of replacing a storage device of the storage apparatus, recovering an I/O path for an external storage device, and adding an I/O path for an external storage device, and

wherein a second processor of an I/O processing board used for I/O processing of a storage apparatus performs, based on the condition information, at least one of:

(i) the prerequisite manipulation of replacing a communication port for the storage apparatus before the handling manipulation of adding an I/O path for the storage apparatus;

(ii) the prerequisite manipulation of recovering a blocked pool for the storage apparatus before the handling manipulation of recovering a blocked volume for the storage apparatus; and

(iii) the prerequisite manipulation of one of replacing a storage device of the storage apparatus, recovering an I/O path for an external storage device, and adding an I/O path for an external storage device, before the handling manipulation of recovering a blocked pool for the storage apparatus.

wherein the first processor displays information about the accomplishment sequence.

3. A maintenance support method of a maintenance support apparatus that determines an accomplishment sequence of handling manipulations for failures on a storage apparatus,

wherein the maintenance support apparatus stores condition information associating the handling manipulation with a condition concerning at least one of implementation and non-execution of the manipulation and failure handling information associating a failure occurring on the storage apparatus with the handling manipulation, and

wherein the maintenance support apparatus determines an accomplishment sequence of a plurality of handling manipulations so that the plural handling manipulations of a plurality of failures occurring on the storage apparatus satisfies the condition,

wherein the condition applies to an unnecessary manipulation that renders the handling manipulation unnecessary, and

wherein the maintenance support apparatus determines an accomplishment sequence for each of the handling manipulations so that the accomplishment sequence allows the handling manipulation to be accomplished before other handling manipulations that are deemed unnecessary by the accomplishment of the handling manipulation and prevents other unnecessary handling manipulations from being accomplished,

wherein the condition information contains at least one of:

(A) the handling manipulation is to restart an I/O processing board used for I/O processing of a storage apparatus, and the unnecessary manipulation is to recover a second processor of the I/O processing board;

(B) the handling manipulation is to restart an I/O processing board used for I/O processing of a storage apparatus, and the unnecessary manipulation is to reidentify an I/O path for the I/O processing board; and

(C) the handling manipulation is to replace an I/O processing board used for I/O processing of a storage apparatus, and the unnecessary manipulation is to replace memory of the I/O processing board,

wherein the maintenance support apparatus performs, based on the condition information, at least one of:

(i) the handling manipulation of restarting an I/O processing board used for I/O processing of a storage apparatus before the unnecessary manipulation of recovering a second processor of the I/O processing board;

(ii) the handling manipulation of restarting an I/O processing board used for I/O processing of a storage apparatus before the unnecessary manipulation of reidentifying an I/O path for the I/O processing board; and

(iii) the handling manipulation of replacing an I/O processing board used for I/O processing of a storage apparatus before the unnecessary manipulation of replacing memory of the I/O processing board.

4. A computer program product comprising a non-transitory computer-readable recording medium containing a maintenance support program that allows a computer to perform processes to determine an accomplishment sequence of handling manipulations for failures on a storage apparatus,

wherein the computer stores:

condition information that associates the handling manipulation with a condition concerning at least one of accomplishment and non-accomplishment of the manipulation; and

failure handling information that associates a failure occurring on the storage apparatus with the handling manipulation, and

wherein the maintenance support program allows the computer to determine an accomplishment sequence of a plurality of handling manipulations so that a plurality of the handling manipulations of a plurality of failures occurring on the storage apparatus satisfies the condition,

wherein the condition renders accomplishment of the handling manipulation unnecessary,

wherein the maintenance support program determines an accomplishment sequence for each of the handling manipulations so that the accomplishment sequence prevents the accomplishment of a manipulation that satisfies a condition to render accomplishment of the handling manipulation unnecessary,

wherein the condition information contains at least one of:

(A) the handling manipulation is to acquire a dump of a specified memory area, and the condition rendering the handling manipulation unnecessary is availability of dump data for the specified area acquired after an occurrence of failure; and

(B) the handling manipulation is to unlock the storage apparatus, and the condition rendering the handling manipulation unnecessary is an unlocked state of the storage apparatus, and

wherein the maintenance support program performs, based on the condition information, at least one of:

(i) the handling manipulation of acquiring a dump of a specified memory area before the condition of dumping data for the specified area acquired after an occurrence of failure; and
