SWAP command

Use the SWAP command to initiate an operator request for dynamic device reconfiguration (DDR) and to activate or deactivate system-initiated DDR. DDR is described in Responding to failing devices.

Because a system-initiated DDR swap is automated in an IBM® 3495 Tape Library Dataserver, the operation usually completes without operator intervention. Messages that do not require operator intervention are not sent to the console but are sent to the hardcopy log, where they are available for tracing and debugging. Note that the operator can still initiate swaps in an IBM 3495 Tape Library Dataserver. Table 1 summarizes the information that the SWAP command provides. Use it to access the pages on which you can find details about a particular use of the SWAP command.
