Connectivity
The following issues deal with the iSCSI FC4-16IP blade connectivity between devices.
NOTE
The iSCSI blade FC4-16IP is not supported in the Brocade DCX or DCX-4S enterprise-class platforms.
Symptom iSCSI host reports connection failed.
Probable cause and recommended action
Network connectivity is having problems.
Verify the IP address using the portShow ipif <slot>/ge<port> command.
Verify the IP route using the portShow iproute <slot>/ge<port> command.
Ping the PC using the portCmd - -ping <slot>/ge<port> -s <source IP> -d <destination IP>
command.
Make corrections to the IP information using the portCfg command.
Below is an example to verify if packets can be sent to the destination IP address with maximum
wait_time specified. Note that a backslash ( \ ) is used to skip the return character so you can
continue the command on the next line without the return character being interpreted by the shell.
