10-1 Common problems and solutions
The following table lists the most common problems that occur on the Device Manager server, and
describes how to resolve them.
Table 10-1 Common problems and solutions
No. Problem and cause Solution
1 PROBLEM: Inconsistencies in LUNs and
logical group information. LUNs disappear
or logical group information is inconsistent
between Device Manager servers.
CAUSE: Multiple Device Manager servers
are managing the storage subsystems.
SOLUTION: Never have more than one active
Device Manager server managing a single
storage array at a time. Device Manager was
designed to manage multiple storage
subsystems, but not to cooperate with other
Device Manager servers to manage the same
storage array.
More than one active Device Manager client is
not a problem.
