Checking The Iscsi Os Driver; Checking The Operating System; Checking The Applications - ATTO Technology iPBridge 2600 Installation And Operation Manual

4 Verify that the hosts are running the
recommended driver and firmware level for the
iSCSI host adapter or NIC vendor.
5 Verify that the hosts and the iPBridge are using
the same port number to communicate via
iSCSI. The default port number for the iPBridge
is 3260. Refer to iSCSIPortNumber
6 Make sure the host adapter/NIC is configured
to log into the iPBridge. Some iSCSI host
adapters do not re-login upon reboot or
unplug/replug event without marking a check
box.
7 Some older switches cannot autonegotiate
between the host and the switch properly. You
may have to force the host or switch to the
desired speed.
For a NIC using an OS iSCSI driver, continue to the
iSCSI OS driver section.

Checking the iSCSI OS driver

This section is for hosts using a driver that allows the
OS to talk to iSCSI targets via a NIC, not an iSCSI
storage adapter.
1 A PC using an iSCSI storage adapter and an
iSCSI OS driver might not work correctly on the
same machine. Check with the vendors to
make sure they are compatible.
2 Verify that the PC has the latest iSCSI driver as
well as the required service packs and patches.
Check with the iSCSI OS driver vendor for more
information.
3 Verify that the iSCSI OS driver has started.
Look under Device Manager for Windows or
lsmod for Linux.
4 Verify that the iSCSI OS is still looking for the
iPBridge at the right IP address.
5 If using DHCP, verify that the DHCP server is
assigning the correct IP information to the host.
Refer to
23.
6 Verify that the NIC is configured with the correct
IP information.
on page 55.
7 Verify that the hosts and the iPBridge are using
the same port number to communicate via
iSCSI. The default port number for the iPBridge
is 3260. Refer to
8 Check cable integrity. Check the cables for
solid connections. Make sure they are plugged
in properly. Inspect cable ends for broken clips
and improper wiring.

Checking the Operating System

1 Verify that the OS has the required service
packs or patches installed. If not, obtain the
proper service packs and patches and install
them.
2 Some iSCSI host adapters and iSCSI OS
drivers do not always automatically find new
targets when plugged in or when forced to
rescan. Reboot the hosts.
3 Check if the vendor has a new driver. If so,
install it.

Checking the applications

1 Verify that the application is running the latest
device drivers for the devices connected to
iPBridge. If not, get the latest device drivers and
install them.
2 Verify with the application vendor if the iSCSI
technology is supported on the version of the
application being used.
