------------------------------
Summary: xCAT2.pm displays "Use of uninitialized value in
concatenation" warnings
Key: VCL-677
URL: https://issues.apache.org/jira/browse/VCL-677
Project: VCL
Issue Type: Bug
Components: vcld (backend)
Affects Versions: 2.3
Reporter: Andy Kurth
Assignee: Andy Kurth
Priority: Minor
Fix For: 2.3.3
There are a few places in xCAT2.pm where string values aren't checked before
manipulating them which results in the following in vcld.log:
|19409|2103947:2192365|new| ---- WARNING ----
|19409|2103947:2192365|new| 2013-02-24

uninitialized value in concatenation (.) or string at

Old code which is calling open() to run commands on the management node should
be replaced with $self->mn_os->exectute and the output checked properly.
