Abstract
A problem to be solved is to enable the user to read out data stored in a logical unit in a power saving state in a short time in a storage system having a power saving function such as stopping the spindle of the HDD. To solve the problem, candidate document file information is read out according to the keywords inputted by the user from a search system, a predetermined number of document file names are extracted from the highest candidates in the candidate document file information, and the power saving function of the logical units actually storing the extracted document files is controlled (switch the state from the power saving state to the normal operation state).
Claims14
An information processing system including:
- a storage that includes one or more logical units, each of the logical units constituted by one or more disk drives;
- and a host computer that issues an instruction to access the storage to acquire and store data, wherein
- the host computer comprises:
- a search engine that executes a search according to an inputted instruction;
- and
- an LU startup/power saving processor that generates a state transition command for switching the logical units from a power saving state, in which the access is not allowed, to a normal operation state, in which the access is allowed, when a candidate file list indicated in a search result obtained by the search engine is extracted, and
- the storage comprises:
- a disk controller that activates spindles of the disk drives constituting the logical units to switch the logical units from the power saving state to the normal operation state in response to the state transition command,
- wherein the LU startup/power saving processor generates a first state transition command for switching the logical units storing predetermined N cases (integer N>1) of files in a candidate file list indicated in the search result obtained by the search engine from the power saving state, in which the access is not allowed, to the normal operation state, in which the access is allowed, when the candidate file list is extracted, and the disk controller activates the spindles of the disk drives constituting the relevant logical units in response to the state transition command.

(canceled)
A program for controlling an information processing system comprising:
- a storage that includes one or more logical units, each of the logical units constituted by one or more disk drives;
- and a host computer that accesses the storage to acquire and store data, the program causing:
- an LU startup/power saving processor to generate a state transition command for switching the logical units from a power saving state, in which the access is not allowed, to a normal operation state, in which the access is allowed, when a candidate file list indicated in a search result obtained by a search engine that executes a search according to an inputted instruction is extracted in the host computer;
- and
- a disk controller to activate spindles of the disk drives constituting the logical units to switch the logical units from the power saving state to the normal operation state in response to the state transition command in the storage,
- wherein the LU startup/power saving processor generates a state transition command for switching the logical units storing predetermined N cases (integer N>1) of files in a candidate file list indicated in the search result obtained by the search engine from the power saving state, in which the access is not allowed, to the normal operation state, in which the access is allowed, when the candidate file list is extracted, and the disk controller activates the spindles of the disk drives constituting the relevant logical units in response to the state transition command.
