Configuring a tape LUN

This example shows how to configure a tape storage device. The basic setup procedure is the same
as for disk devices. Only a subset of configuration options and policy settings are available for tape
LUNs. Refer to
1. Create a zone that includes the initiator (host) and the target port. Refer to the section
2. Create a CryptoTarget container of type tape. Refer to the section
3. Configure the Crypto tape LUN. Refer to the section

Operation Succeeded
b. Add an initiator to the CryptoTarget container "my_tape_tgt".
FabricAdmin:switch> cryptocfg --add -initiator my_tape_tgt \
