I am using iscsi to connect a Centos 5.2 server to a Promise Tech Vtrak
M610i
On the linux box, I have
iscsi-initiator-utils-6.2.0.868-0.18.el5
2.6.18-92.1.13.el5.centos.plus #1 SMP Wed Oct 1 13:41:35 EDT 2008 x86_64
x86_64 x86_64 GNU/Linux
The Promise array is on a separate subnet from the linux host.
service iscsi start
iscsiadm --mode discovery --type sendtargets --portal 128.128.181.69 -I
iface1
iscsiadm --mode node iqn.1994-12.com.promise.dd.64.55.55.1.0.0.20
--portal 128.128.181.69 --login
and then the drives are mountable:
Feb 22 11:13:22 ndsfdh1 kernel: iscsi: registered transport (tcp)
Feb 22 11:13:22 ndsfdh1 kernel: iscsi: registered transport (iser)
Feb 22 11:13:22 ndsfdh1 iscsid: iSCSI logger with pid=28337 started!
Feb 22 11:13:23 ndsfdh1 iscsid: transport class version 2.0-724. iscsid
version 2.0-868
Feb 22 11:13:23 ndsfdh1 iscsid: iSCSI daemon with pid=28338 started!
Feb 22 11:14:43 ndsfdh1 iscsid: received iferror -38
Feb 22 11:14:43 ndsfdh1 iscsid: connection1:0 is operational now
we have a dedicated interface for iscsi traffic, contents of
/var/lib/iscsi/ifaces/iface1
iface.transport_name = tcp
iface.hwaddress = 00:1D:09:2F:15:B2
after about 24 hours, we see the following in /var/log/messages (not in
order)
iscsid: connect failed (111)
iscsi: cmd 0x28 is not queued (8)
iscsi: cmd 0x2a is not queued (8)
iscsi: detected conn error (1011)
Kernel reported iSCSI connection 1:0 error (1011) state (3)
iscsid: connect failed (113)
The only way to get the drives remounted is to shut down iscsi service
and then reboot the array and restart the iscsi service and remount.
I have read on other threads there are other versions of the iscsi
software, like open-iscsi as opposed to iscsiadm and such. If there are
better packages or if I need additional software to make this connection
more reliable, I am open to suggestions. I am new to using the iscsi
protocol.
Directly connected, the array worked fine with no errors (10.0.0.1 /
10.0.0.2 network setup)
One theory we have is that there is a 100 MB switch somewhere between
the linux box and the array that we don't know about.
Any suggestions for troubleshooting this issue would be appreciated.
thank you,
