FS8-18 blade removal and replacement

The following procedures identify steps for removing and replacing an FS8-18 blade in a DCX
Backbone chassis. The procedures assume that the replacement blade is being inserted in the
same slot as the old blade that was removed.

1. Enter the cryptocfg

name, the LUN number and the initiator PWWN.
FabricAdmin:switch> cryptocfg --resume_rekey my_disk_tgt 0x0 \

Operation Succeeded
2. Check the status of the resumed rekey session.
FabricAdmin:switch> cryptocfg --show -rekey -all
Read all data off the LUN and write it to another LUN. In this case, you can cancel the rekey
session by removing the LUN from its container and force committing the transaction.
Stop all traffic I/O from the initiators accessing the LUN before removing the LUN to avoid I/O
failure between the initiators and the LUN. If the LUN is exposed to more than one initiator
under different LUN Numbers, remove all exposed LUN Numbers. When there are multiple
paths to a LUN, you must remove the LUNs from all exposed CryptoTarget containers before
you commit the transaction. Failure to do so may result in a potentially catastrophic situation
where one path ends up being exposed through the encryption switch and another path has
direct access to the device from a host outside the protected realm of the encryption platform.

2. Commit the configuration with the
associated configuration data in the configuration database. The data remains on the
removed LUN in an encrypted state.
