Chapter 3 Troubleshooting

Basic Verification

SCSI Devices—Verify that the SCSI devices on a particular SCSI Bus can be seen in the by the TC2201. Check the Discovery page to verify visibility of devices. If the TC2201 can not see the devices, verify SCSI configuration, cabling, and termination.

Even if the SCSI devices are displayed, they are not accessible unless the mapping mode is auto-assigned or another non-empty map is used.

Verify iSCSI Connection

If SCSI devices are recognized on the SCSI buses, but do not appear to the

 

 

iSCSI host, it may be that the iSCSI link is not properly established. Most

 

 

switches have link indicators, showing link status. When the TC2201 is

 

 

connected and powered-on, this link

 

 

indicator should show a good link. If it does not, check the cabling or

 

 

connections. As a means of verifying link integrity when connected to a

 

 

functional host, disconnecting then reconnecting the Ethernet cable

 

 

should cause momentary activity of this indicator as the link itself re

 

 

initializes. Also verify that the media type of the TC2201 and attached

 

 

switch are of corresponding types.

If no devices are listed, verify the TC2201 configuration, iSCSI HBA

 

 

configuration, and cabling.

 

 

If devices are listed, verify iSCSI HBA mapping mode and device

 

 

addresses on the TC2201.

changes are made.
