Asha,
I'm not sure what went wrong. Something must have happened during your HA setup. You might check a couple different things, first you might check out your HA policies and HA group setup. The other thing you might make sure is that you only generate one mkek and hmac on one hsm (I use direct slot and not the HA virtual slot for this) and then replicate (vtl haAdmin -synchronize). If the HA group is setup properly it should replicate your mkek and hmac across the other HSMs in the HA group. As a side note, the pkcs11 plugin in Barbican currently retrieves the mkek and hmac by label, so make sure you don't have multiple keys in the HSM with the same label.

Hi John ,
Thanks a lot for providing me the response:)
I followed the link[1] for configuring the HA SETUP
[1] : http://docs.aws.amazon.com/cloudhsm/latest/userguide/ha-setup.html
the final step in the above link is haAdmin command which is run on the client side(on Barbican) .
The slot 6 is the virtual slot(only on the client side and not visible on LUNA SA ) and 1 and 2 are actual slots on LUNA SA HSM
Please find the response below :
[root at HSM-Client bin]# ./vtl haAdmin show
================ HA Global Configuration Settings ===============
HA Proxy: disabled
HA Auto Recovery: disabled
Maximum Auto Recovery Retry: 0
Auto Recovery Poll Interval: 60 seconds
HA Logging: disabled
Only Show HA Slots: no
================ HA Group and Member Information ================
HA Group Label: barbican_ha
HA Group Number: 1489361010
HA Group Slot #: 6
Synchronization: enabled
Group Members: 489361010, 489361011
Standby members: <none>
Slot # Member S/N Member Label Status
====== ========== ============ ======
1 489361010 barbican2 alive
2 489361011 barbican3 alive
After knowing the virtual slot HA number , I ran the pkcs11-key-generation with slot number 6 which did create mkek and hmac in slot/partition 1 and 2 automatically . I am not sure why do we have to replicate the keys between partitions? Configured the slot 6 on the barbican.conf as mentioned in my first email
Not sure what might be the issue and
It would be great if you could tell me the steps or where I would have gone wrong.
Thanks and Regards,
Asha Seshagiri

Asha,
I've used the Safenet HSM "HA" virtual slot setup and it does work. However, the setup is very interesting because you need to generate the MKEK and HMAC on a single HSM and then replicate it to the other HSMs out of band of anything we have in Barbican. If I recall correctly, the Safenet Luna docs mention how to replicate keys or partitions between HSMs.

Subject: Barbican : Unable to create the secret after Integrating Barbican with HSM HA
Hi All ,
I am working on Integrating Barbican with HSM HA set up.
I have configured slot 1 and slot 2 to be on HA on Luna SA set up . Slot 6 is a virtual slot on the client side which acts as the proxy for the slot 1 and 2. Hence on the Barbican side , I mentioned the slot number 6 and its password which is identical to that of the passwords of slot1 and slot 2 in barbican.conf file.
Please find the contents of the file :
# ================= Secret Store Plugin ===================
[secretstore]
namespace = barbican.secretstore.plugin
enabled_secretstore_plugins = store_crypto
# ================= Crypto plugin ===================
[crypto]
namespace = barbican.crypto.plugin
enabled_crypto_plugins = p11_crypto
[simple_crypto_plugin]
# the kek should be a 32-byte value which is base64 encoded
kek = 'YWJjZGVmZ2hpamtsbW5vcHFyc3R1dnd4eXoxMjM0NTY='

dogtag_host = localhost
dogtag_port = 8443
nss_db_path = '/etc/barbican/alias'
nss_db_path_ca = '/etc/barbican/alias-ca'
nss_password = 'password123'
simple_cmc_profile = 'caOtherCert'
[p11_crypto_plugin]
# Path to vendor PKCS11 library
library_path = '/usr/lib/libCryptoki2_64.so'
# Password to login to PKCS11 session
login = 'test5678'
# Label to identify master KEK in the HSM (must not be the same as HMAC label)
mkek_label = 'ha_mkek'
# Length in bytes of master KEK
mkek_length = 32
# Label to identify HMAC key in the HSM (must not be the same as MKEK label)
hmac_label = 'ha_hmac'
# HSM Slot id (Should correspond to a configured PKCS11 slot). Default: 1
slot_id = 6
Was able to create MKEK and HMAC successfully for the slots 1 and 2 on the HSM when we run the pkcs11-key-generation script for slot 6 which should be the expected behaviour.
[root at HSM-Client bin]# python pkcs11-key-generation --library-path '/usr/lib/libCryptoki2_64.so' --passphrase 'test5678' --slot-id 6 mkek --label 'ha_mkek'
Verified label !
MKEK successfully generated!
[root at HSM-Client bin]# python pkcs11-key-generation --library-path '/usr/lib/libCryptoki2_64.so' --passphrase 'test5678' --slot-id 6 hmac --label 'ha_hmac'
HMAC successfully generated!

Would like to know wheather Barbican supports Virtual slot configuration since have mentioned the slot # 6 under in barbican.conf file and has anyone tested HSM HA setup with Barbican.
Any help would highly be appreciated!
