Page 65: Table 5 2U Enclosure Non-Fault Conditions
Identify 2U enclosure fault conditions Fault conditions do not necessarily cause the 2U enclosure to cease functioning. Fault conditions do require a system administrator to take an appropriate action to clear the fault condition. The input/output modules (IOMs) allow you to choose from multiple fault isolation methods. This section provides the basic methodology used to locate faults within a storage system, then identify the affected FRUs. -
Page 66: Table 6 5U Enclosure Non-Fault Conditions
When performing fault isolation and troubleshooting steps, select the option or options that best suit your site environment. Use of any one of the following options is not mutually exclusive to the use of another option. The order for the options is based on frequency of use. - Page 67 CAUTION When you suspect a drive module or connection is the fault, halt all input and output operations to the disk group or groups from all hosts as a data protection precaution. Make sure your regularly scheduled backup is good and that you conduct another backup at the time of failure as an additional data protection precaution.
