Category:	MySQL Cluster Manager: CLI	Severity:	S3 (Non-critical)
Version:	1.3.1	OS:	Any
Assigned to:		CPU Architecture:	Any

Description:
show status accepts a combination of --backup and --process, but rejects many other option invalid combinations.

How to repeat:
mcm> show status --backup --process mycluster;
+-----------------------------------------+
| Command result                          |
+-----------------------------------------+
| No backup currently active in mycluster |
+-----------------------------------------+
1 row in set (0.09 sec)

mcm> 

Suggested fix:
Return an error if both --backup and --process are specified.

Hello Daniel,

Umesh

Added the following entry to the MySQL Cluster Manager 1.3.2 changelog:

"Client: When using the 'show status' command with the --backup option, the MySQL Cluster Manager client sometimes accepted an additional option, which was actually meaningless. This fix makes the client throw an error when any other option is used in combination with --backup."
