SANTap Issues
Host Login Problems
Host login problems can be caused by DVT limitations, connectivity, or other issues.
To diagnose host login problems, follow these steps:
Step 1 Use the show santap vttbl dvt dvt-pwwn command to display SANTap information for the DVT.
Step 2 Use the show santap vttbl dvt dvt-pwwn host-pwwn command to display SANTap information for the
DVT and the host.
Step 3 Enable logging on the appropriate SSM module.
Step 4 Issue the following debug commands:
a. debug vsd vfc-felogin
b. debug partner 0x92810000 d1
c. debug partner 0x92810000 d2
Step 5 Review the logs to determine the problem and then take the appropriate corrective action.
ITL Problems
An ITL problem may occur if the number of ITLs exceeds the limitations for the version of Cisco
SAN-OS and SSI in use. For specific ITL limitations, see the “Limitations” section on page 23-2
To diagnose and resolve ITL problems, follow these steps:
Step 1 Use the show isapi dpp 4 queue command to display DPP queue information.
Step 2 Verify that the number of ITLs on a DPP is within the limitations for the version of Cisco SAN-OS and
SSI in use. Use the show isapi dpp 4 queue incl LUN and show isapi dpp 4 queue count commands.
Step 3 Verify that the number of ITLs on an SSM is within the limitations for the version of Cisco SAN-OS and
SSI in use. Issue the show isapi dpp all queue command, using the incl LUN and count parameters.
Common Mismatch Problems
Problems are often caused by mismatching component versions, or using devices that are not supported
by the interoperability matrix.
The following lists common mismatch situations:
Table 23-3 Common SANTap Mismatch Problems
