[Stgt-devel] Seeing weird problem with iscsiadmin logins causing multuple nexuses to be created ...

[Richard Sharpe]

Hi,

After I restarted my two servers (after setting the MTU to 9000 on
each server) I am now getting weirdness when I try to reconnect my
iSCSI connection (login) from the initiator ...

Here is what I see on the target. There are two I_T nexuses, #21 and
#28 ... weird ... perhaps it is time to break out wireshark.

[root at localhost tgt-20080715]# ./usr/tgtadm --lld iscsi --op show --mode target
