Method for controlling storage system

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;
• and
• when one of said channel control portions detects occurrence of failure in said channel control portion, said channel control portion gives a notice of occurrence of failure to said computer.

• 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;
• and
• when one of said disk control portions detects the fact that dump information output from one of said channel control portions is written in one of said storage devices, said disk control portion gives a notice of occurrence of failure in said channel control portion to said computer.

A storage system comprising:

• 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;
• said storage system further comprising means by which when one of said channel control portions detects occurrence of failure in a channel control portion, said channel control portion gives a notice of occurrence of failure to said computer.

A program used in 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 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;
• said program providing each of said channel control portions with a function by which when one of said channel control portions detects occurrence of failure in said channel control portion, said channel control portion gives a notice of occurrence of failure to said computer.
