• Avoid changing the configuration of any LUN that belongs to a CTC/LUN configuration while the rekeying process for that LUN is active. If the user changes the LUN's settings during manual or auto, rekeying 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 rekeying processes running in all CTCs and corrupts any LUN engaged in a rekeying 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 CTCs, which will in turn remove the associated frame redirection zone information. Make sure to back up all data before taking this action. • 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 CTC or LUNs failing and may cause the LUNs to be disabled. The user can check for outstanding zoning transactions by issuing the CLI command cfgtransshow: DCX_two:root> cfgtransshow There is no outstanding zoning transaction • Each LUN is uniquely identified by the HP Encryption Switch or HP Encryption Blade using the LUN's serial number. The LUN serial numbers must be unique for LUNs exposed from the same target port. The LUN serial numbers must also be unique for LUNs belonging to different target ports in nonmultipathing configurations. Failure to ensure unique LUN serial numbers results in nondeterministic behavior and may result in faulting of the HP Encryption Switch or HP Encryption Blade. • When creating an HA cluster or EG with two or more HP Encryption Switch/Encryption Blades, the GE ports (I/O sync links) must be configured with an IP address for the eth0 and eth1 Ethernet interfaces using ipaddrset. In addition, the eth0 and eth1 Ethernet ports should be connected to the network for redundancy. These I/O sync links connections must be established before any Re-Key, First Time Encryption, or enabling EE for crypto operations. Failure to do so results in HA Cluster creation failure. If the IP address for these ports is configured after the EE was enabled for encryption, HP Encryption Switch needs to be rebooted and Encryption Blades should be slotpoweroff/slotpoweron to sync up the IP address information to the EEs. If only one Ethernet port is configured and connected to a network, data loss or suspension of Re-Key may occur when the network connection toggles or fails. • initEE will remove the existing master key or link key. Backup the master key by running cryptocfg -exportmasterkey and cryptocfg -export -currentMK before running initEE. After initEE, regEE and enableEE, run cryptocfg -recovermasterkey to recover the master key previously backed up, or in the case of fresh install run cryptocfg - genmasterkey to generate a new master key. If you are using SKM, establish a trusted link with SKM again. Certificate exchange between key vaults and switches are not required in this case. • The disable EE interface CLI cryptocfg --disableEE [slot no] should be used only to disable encryption and security capabilities of the EE from the Fabric OS Security Admin in the event of a security compromise. When disabling the encryption capabilities of the EE using the noted commands, the EE should not be hosting any CTCs. Ensure that all CTCs hosted on the HP Encryption Switch or HP Encryption Blade are either removed or moved to a different EE in the HA Cluster or EG before disabling the encryption and security capabilities. • Whenever initNode is performed, new certificates for CP and KAC (SKM) are generated. Hence, each time InitNode is performed, the new KAC Certificate must be loaded onto key vaults for (SKM. Without this step, errors will occur, such as key vault not responding and ultimately key archival and retrieval problems. • The HTTP server should be listening to port 9443. SKM is supported only when configured to port 9443. 40
