Greetings To All!

Results of uname -a: SunOS XXXXXXb1s5 5.9 Generic_118558-20 sun4u sparc SUNW,Serverblade1

I am running SUNWexpl version 5.13

I am getting the following root e-mail message via Logcheck alert:


Your "cron" job on XXXXXXb1s5
/opt/SUNWexplo/bin/explorer -e -q # SUNWexplo

produced the following output:

WARNING: EXP_SERIAL_83256cea not set!

1 warnings found in /etc/opt/SUNWexplo/default/explorer


Can anyone tell me what this message means...? I've googled it but have not been able to come up with anything. Your help is much appreciated.
Thanks!
