The Identify a Device Attached to an SCSI Hot Swap Enclosure Device function is used to helpidentify the location of a device attached to a SCSI Hot Swap Enclosure device. This function lists all theslots that support hot swap that are occupied or empty. When a slot is sele ted for identification, the visualindicator for the slot is set to the identify state.The Attach a Device to an SCSI Hot Swap Enclosure Device function lists all empty hot-swap slots thatare available for the insertion of a new device. After a slot is selected, the power is removed. If available,the visual indicator for the selected slot is set to the remove state. After the device is added, the visualindicator for the selected slot is set to the normal state, and power is restored.The Replace/Remove a Device Attached to an SCSI Hot Swap Enclosure Device function lists allpopulated hot-swap slots that are available for removal or replacement of the devices. After a slot isselected, the device populating that slot is unconfigured, the power is removed from that slot. If theunconfigure operation fails, it is possible that the device is in use by another application. In this case, thecustomer or system administrator must be notified to quiesce the device. If the unconfigure operation issuccessful, the visual indicator for the selected slot is set to the remove state. After the device is removedor replaced, the visual indicator, if available for the selected slot, is set to the normal state, and power isrestored.Note: Before you remove the device, be sure that no other host is using it.The Configure Added/Replaced Devices function runs the configuration manager on the parent adaptersthat had child devices added or removed. This function ensures that the devices in the configurationdatabase are configured correctly.Standalone Diagnostics has restrictions on using the SCSI hot-plug Manager. For example:v Devices being used as replacement devices must be exactly the same type of device as the devicebeing replacedv New devices may not be added unless a device of the same FRU part number already exists in thesystem, because the configuration information for the new device is not known after the StandaloneDiagnostics are booted.You can run this task directly from the command line. See the following command syntax:diag -d device -T"identifyRemoveORdiag -d device -T"identifyRemove -a [identify|remove ]Flags Description-a Specifies the option under the task.-d Indicates the SCSI device.-T Specifies the task to run.RAID Hot-Plug DevicesThis task allows the user to identify, or remove a RAID device in a system unit that uses a SCSI EnclosureServices (SES) device. The following subtasks are available:v Normalv Identifyv RemoveThe Normal subtask is used to return a RAID hot-plug device to its normal state. This subtask is usedafter a device has been identified or replaced. This subtask lists all channel/IDs of the RAID and the statusof the devices that are connected. A device in its normal state has power and the check light is off.98 Eserver pSeries 655 User’s Guide
