Troubleshooting Troubleshooting Event Code Descriptions Event Number (DEC/hex) Event Name Event Predictive Suspected Logged Maintenance Components Implication Description 143/0x8f Duplicate Disk Drive Identifier Y Single Controller Occurrence Erroneous Operator Activity As part of its stamp, each drive indicates its logical position in the disk set to which it is attached. This event indicates that the controller has detected two disk drives with identical stamps, indicating that they occupy the same logical position of the same disk set. The most likely source of this error is the erroneous assignment of duplicate disk set ID's by the controller. This would generally originate with incorrect controller serial number assignment, and/or loss of NVRAM. This error would also occur if a user made an image copy of a drive. The solution to this difficult problem involves two steps: 1. Try to determine which of the disk drives share the conflicting stamp. This can be done by removing disk drives until the problem disappears. Concentrate on any previously used or unincluded disks first. 2. When you have isolated the two conflicting disks, determine which one contains valid data. 161
