Crypto LUN configuration
3
NOTE
If you are using VMware virtualization software or any other configuration that involves mounted file
systems on the LUN, you must enable first-time encryption at the time when you create the LUN by
setting the
–-
enable_encexistingdata option with the
–-
add
-
LUN command. Failure to do so
permanently disconnects the LUN from the host and causes data to be lost and unrecoverable.
1. Log in to the group leader as Admin or FabricAdmin.
2. Enter the cryptocfg
--
add
-
LUN command followed by the CryptoTarget container Name, the
LUN number or a range of LUN numbers, the PWWN and NWWN of the initiators that should be
able to access the LUN. The following example adds a disk LUN enabled for encryption.
FabricAdmin:switch> cryptocfg --add -LUN my_disk_tgt 0x0 \
10:00:00:00:c9:2b:c9:3a 20:00:00:00:c9:2b:c9:3a -encrypt
Operation Succeeded
3. Commit the configuration.
FabricAdmin:switch> cryptocfg --commit
Operation Succeeded
CAUTION
When configuring a LUN with multiple paths, do not commit the configuration before you have
added all the LUNs with identical policy settings and in sequence to each of the CryptoTarget
containers for each of the paths accessing the LUNs. Failure to do so results in data corruption.
Refer to the section
“Configuring a multi-path Crypto LUN”
4. Display the LUN configuration. The following example shows default values.
FabricAdmin:switch> cryptocfg --show -LUN my_disk_tgt0 \
10:00:00:00:c9:2b:c9:3a -cfg
