“mailbox command 17 failure status FFF7” Message

If one or more of your Microsoft Windows hosts are using an Emulex HBA driver, you may see the following message in Windows Event Viewer:

“mailbox command 17 failure status FFF7”

This message can be safely ignored. The HBAAPI is being used to access data in the FLASH memory of the adapter that does not exist and this is causing the event to be logged. This issue has been seen with version 5.2.2 of the driver.

”Process Has an Exclusive Lock” Message

You will receive a message resembling the one shown below if a process has already locked the EMC Symmetrix storage system and you attempt a process that requires a lock on the Symmetrix storage system. The Symmetrix storage system can become locked for many reasons. For example, the storage system becomes locked when it performs LUN mapping, LUN masking or Discovery Data Collection/Get Details. The Symmetrix storage system may also remain locked after a provisioning operation has failed.

“SYMAPI routine SymDevMaskSessionStart failed with error code 188: The operation failed because another process has an exclusive lock on the local Symmetrix.”

After the management server has detected the lock on the Symmetrix storage system, it tries to access the storage system for 15 minutes and logs the errors.

If you receive the error message, determine if someone is performing an operation that requires a lock, such as LUN mapping, LUN masking or Discovery Data Collection/Get Details. This also applies even if one of the processes is being used by a third-party product, such as for LUN masking. If so, wait until the process is complete. Only manually remove the lock if you are certain that no other processes are occurring on the storage system. To learn how to remove the lock, refer to the documentation for the Symmetrix storage system.
