In the newest version of the Nagios plugin check_equallogic (20100809) there has been a change in the check of the ISCSI connection (type conn). Due to a wrong assumption all the given connections were taken as one. This works fine if only one Equallogic (one member) is used, but as soon as several members are in a group, the numbers wouldn't be correct anymore.
The new version resolves this issue and the total number of ISCSI connections of the group is now used. You can download version 20100809 here.
As always, feedback is very welcome.
