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 non-multipathing configurations. Failure to ensure unique LUN serial numbers results in non-deterministic behavior and may result in faulting of the HP Encryption Switch or HP Encryption Blade. • When creating an HA Cluster or Encryption Group 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 Ethernet interface using ipaddrset. In addition, both 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 ReKey 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 Secure Key Manager (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. Secure Key Manager is supported only when configured to port 9443. • When all nodes in an Encryption Group (HA Cluster or DEK Cluster) are powered down (due to catastrophic disaster or a power outage to the data center) and later nodes come back online (in the event of the Group Leader (GL) node failing to come back up or the GL node being kept powered down) the member nodes lose information and knowledge about the Encryption Group. This leads to no crypto operations or commands (except node initialization) being available on the member nodes after the power-cycle. This condition persists until the GL node is back online. • Workaround. In the case of a datacenter power down, bring the GL node online first, before the other member nodes are brought back up. In the event of the GL node failing to come back up, the GL node can be replaced with a new node. The following are the procedures to allow an EG to function with existing member nodes and to replace the failed GL node with a new node • Make one of the existing member nodes the Group Leader node and continue operations: 1. On one of the member nodes, create the Encryption Group with the same Encryption Group name. This will make that node the GL node and the rest of the Crypto Target Container and Tape Pool related configurations will remain intact in this Encryption Group. 28
