error

When i want to check portstate, i got error message:

Use of uninitialized value in concatenation (.) or string at /usr/local/nagios/libexec/check_emc_clariion.pl line 462.

command is:
check_emc_clariion.pl -H -u login -p password -t portstate –sp A –port 0

if i send command without –port 0, i got check of all ports normal.

test on VNX 5300
