Here the method of setting the I/O Response Time Assurance Function for a already created class will be explained.

1. Set the I/O Response Time Assurance.

   Example) If setting the I/O response time to 23 seconds and the panic mode to on for the class Class

   # sdxattr -C -c Class -a iotimeout=on:23:on

2. Check the settings of the I/O Response Time Assurance.

   Example) If checking the settings of the I/O Response Time Assurance of the class Class

   # sdxinfo -I -c Class

   If the value set in procedure 1 is displayed in the MODE field, the TIME field and the PANIC field of the specified class the setup of the I/O Time Response Assurance is complete.
