HP A7533A - Brocade 4Gb SAN Switch Base Release Note page 42

to Block-0 again (and if the key is expired), a new key is created and used henceforth. The expired
key is then marked as read only and used only for restoring data from previously encrypted tapes.
With Windows and Veritas Volume Manager/Veritas Dynamic Multipathing, when LUN sizes less
than 400 MB are presented to the Encryption SAN Switch for encryption, a host panic may occur;
this configuration is not supported for the Fabric OS 6.3 release.
HCL from Fabric OS 6.2.x to 6.3.0 is supported. Cryptographic operations and I/O will be dis-
rupted but other layer 2 traffic will not be.
Relative to the Encryption SAN Switch and a DC SAN Director with Encryption FC blade, all nodes
in the Encryption Group must be at the same firmware level of Fabric OS 6.2 or 6.3 before starting
a rekey or First Time Encryption operation. Make sure that existing rekey or First Time Encryption
operations complete before upgrading any of the encryption products in the Encryption Group.
Also, make sure that the upgrade of all nodes in the Encryption Group to Fabric OS 6.3.0 completes
before starting a rekey or First Time Encryption operation.
To clean up the stale rekey information for the LUN, use one of the following methods:
Method 1
1. Modify the LUN policy from encrypt to cleartext and commit.
The LUN will become disabled.
2. Enable the LUN using cryptocfg --enable
clear-text to encrypt with enable_encexistingdata to enable the first time
encryption and do commit.
This will clear the stale rekey metadata on the LUN and the LUN can be used again for
encryption.
Method 2
1. Remove the LUN from Crypto Target Container and commit.
2. Add the LUN back to the Crypto Target Container with LUN State="clear-text",
policy="encrypt" and enable_encexistingdata set for enabling the First Time
Encryption and commit.
This will clear the stale rekey metadata on the LUN and the LUN can be used again for
encryption.
In an environment with a mixed firmware version (Fabric OS 6.2.x + 6.3.0) Encryption Group,
the I/O link state reported for Fabric OS 6.2.x nodes is unreachable. During a rolling upgrade
from Fabric OS 6.2.0x to 6.3.0, you should see the I/O link status reported as Unreachable
when the cryptocfg
graded to Fabric OS 6.3.0, the show command will accurately reflect the status of the I/O Link.
The I/O link status while performing the rolling upgrade from Fabric OS 6.2.0 to 6.3.0 can be
ignored until all nodes have been upgraded to 6.3.0.
