Method for controlling storage system
First Claim
1. A method of controlling a storage system, wherein:
- said storage system includes;
channel control portions each including a circuit board on which a file access processing portion for receiving file-by-file data input/output requests sent from information processors through a network and an I/O processor for outputting I/O requests corresponding to said data input/output requests to storage devices are formed;
disk control portions for performing data input/output of said storage devices in response to said I/O requests sent from said I/O processors; and
a computer communicatably connected to said channel control portions and said disk control portions;
storage regions for storing dump information concerning programs executed by said channel control portions are set in said storage devices; and
when one of said disk control portions makes a decision that said I/O request accepted from one of said channel control portions is for any one of said set storage regions, said disk control portion gives a notice of occurrence of failure in said channel control portion to said computer.

Abstract
A storage system including: channel control portions each including a circuit board on which a file access processing portion for receiving file-by-file data input/output requests sent from information processors through a network and an I/O processor for outputting I/O requests corresponding to the data input/output requests to storage devices are formed; disk control portions for performing data input/output of the storage devices in response to the I/O requests sent from the I/O processors; and a computer communicatably connected to the channel control portions and the disk control portions. The storage system is formed so that when one of the channel control portions detects occurrence of failure in the channel control portion, the channel control portion gives a notice of occurrence of failure to the computer.
