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.
