No more than 25 LUNs can be added or modified in a single commit operation. Attempts to commit configurations that exceed 25 LUNs will fail with a warning. Note that there is also a five-second delay before the commit operation takes effect. Always ensure that any previously committed LUN configurations or LUN modifications have taken effect before committing additional LUN configurations or additions. All LUNs should be in an Encryption Enabled state before committing additional LUN modifications. • Avoid changing the configuration of any LUN that belongs to a Crypto Target Container/LUN configuration while the re-keying process for that LUN is active. If the user changes the LUN's settings during manual or auto, re-keying or First Time Encryption, the system reports a warning message stating that the encryption engine is busy and a forced commit is required for the changes to take effect. A forced commit command halts all active re-keying processes running in all Crypto Target Containers and corrupts any LUN engaged in a re-keying operation. There is no recovery for this type of failure. • To remove access between a given initiator and target, the user must not only remove the active zoning information between the initiator and target, but must also remove the associated Crypto Target Containers (CTCs), which will in turn remove the associated frame redirection zone information. • Before committing configurations or modifications to the CTC or LUNs on an HP Encryption Switch or HP Encryption Blade, make sure that there are no outstanding zoning transactions in the switch or fabric. Failure to do so results in the commit operation for the Crypto Target or LUNs failing and may cause the LUNs to be disabled. The user can check for outstanding zoning transaction by issuing the cfgtransshow CLI command: HP StorageWorks Fabric OS 6.2.0b release notes 27
