“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.
SYMAPI routine SymDevMaskSessionStart failed with error code 188: The
operation failed because another process has an exclusive lock on the local
Symmetrix.
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. The Symmetrix storage system may also remain locked after a provisioning operation has
failed.
After the management server has detected the lock on the Symmetrix storage system, it tries to
access the storage system for 15 minutes and then 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. 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 before you remove the lock manually. Be sure that no other processes
are occurring on the storage system. To learn how to remove the lock, see the documentation for the
Symmetrix storage system.

Subsystem
Device Driver
(SDD) or MPIO
(multipath I/O)
If you discover an IBM storage system without SDD, incorrect
stitching is displayed in System Manager for the storage
system. You are shown only one path if the storage system is
using MPIO instead of SDD.
