Number error in this line :problem connecting to store-sw-21, port 23: connect timed-out at /pkg/vdc9i/patrol/scripts.D/SAN_SWITCH_IO_THROUGHPUT.D/porterrshow.pl line 11 => tx = 1000000 ... rx = .
Based on the message you have provided, it is looking like to be more a communication issue through the Ethernet management port during the script was running. Seems to be an IP connection issue.
Try to ping the concerned switch and check it global status and Ethernet connection.
Where this message is coming from exactly?
store-sw-21 is one of the Brocade switch?
My understanding is still the same. Script from the management server has failed to collect data from store-sw-21 at a specific point of time.
Does this message has been seen again since last occurrence?
No message after this yet.
