General encryption troubleshooting I 6 TABLE 10 Problem General errors and conditions Resolution Searching or viewing key IDs on an LKM server returns "Not Responding" or "Unknown/Busy" for 20 or more minutes while searching for decommissioned key records. In cases where there are many keys to search through (e.g., one MB or more) LKM database searches may get queued and may not get serviced fast enough, and the request times out. There is no workaround other than retrying. Decommissioning an R2 LUN (remote replication LUN) fails Check the R2 LUN (remote replication LUN) state. If it is in "Disabled (Data with a "Decommission LUN failed because of failure in Decommissioning Failed" state, it indicates that the partner R1 (local) LUN over-writing metadata" error message. was decommissioned with the R1 and R2 LUNs in sync. To decommission the R2 LUN, take the following steps: 1 Split the mirror relationship so each LUN can be independently decommissioned. 2 Write enable the LUN. 3 Decommission the LUN. When a Brocade 7600 application platform is in the data path, I/O errors may be encountered before reaching the scalability limit of 512 LUNs with 16 outstanding I/Os. There is no workaround other than reconfiguring so that the 7600 and the encryption switch/blade are not in the same data path. A performance drop occurs when using DPM on a Microsoft Windows system to back up to a Scalar 500i tape library. Change the DPM behavior to send one request at a time by adding DWORD "BufferQueueSize" under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent, and set the value to 1. Then restart DPM servers: MSDPM, DPMLA, DPMRA. Continuous "Unrecoverable data compression failure" error messages are observed on the console following a High Availability Cluster failback. This is an expected behavior, and you may ignore the messages. If any risk of data corruption is detected, the LUN is disabled, and you are informed and prompted to refresh the Data Encryption Key (DEK).
