Identifying IBM Expandable Storage Plus Disk Enclosures and Disk Drive
Modules
You can identify an IBM Expandable Storage Plus disk enclosure and the disk drive
modules installed in it either by the location code contained in system messages that
refer to that unit, or by using the service aid SCSI Device Identification and Removal.
See “Location Codes” in the operator guide for your system for general information
about location codes.
