Hi,

I'm trying to mount volume from AWS storage gateway and getting following
errors (dmesg):

WARNING: 172.29.16.70 (iqn.1997-05.com.amazon:myvolume): connection error;

The target tested from Windows and Linux and working good.

/etc/iscsic.conf:
myiscsi {
  targetaddress = 172.29.16.70;
}

iscsictl output:
root at backup:~ # iscsictl -L
Target name                          Target portal    State
iqn.1997-05.com.amazon:myvolume      172.29.16.70     Connected: da1

camcontrol output:

<Amazon Storage Gateway 1.0>       at scbus3 target 0 lun 0 (da1,pass2)

Thanks in the advance,
