Problem Statements and Troubleshooting Procedures
This section discusses the troubleshooting procedures for each problem statement.
BACK-END STORAGE NOT FOUND (LOOP/FABRIC)
Check that:
■SANbox SSP is correctly connected to the fabric.
■Storage device is correctly connected to the fabric.
■Zoning of
See "SAN Zoning" on page 5-3 for zoning tips.
■Storage device is configured to allow the SANbox SSP to access the appropriate LUN.
If you are using a RAID with LUN masking, make sure that the SANbox SSP port has access to the LUN. In addition, make sure that physical LUNs from the storage array are configured for Open Systems host mode. The SANbox SSP supports LUNs
■Maximum frame size is correctly set.
Check that SANbox SSP ports are set to the lowest maximum frame size of any device connected to the fabric. See "Configuring Storage" on page
BACK-END STORAGE NOT FOUND BY SVM
Check that:
■SVM device is correctly connected to the fabric.
■Storage device is correctly connected to the fabric.
The storage device must be configured to allow access to the SVM appliance and the SANbox SSP. The LUN may be accessible by the SVM appliance but not by the SANbox SSP. In this case, new virtual volumes created in SVM are not actually created and are missing from the Show Debug Kdisks list.
See "Show Debug Command" on page
■Zoning of
■Storage device is configured to allow SVM to access the appropriate LUN.
Configure storage devices to allow access to the SVM appliance and the SANbox SSP. If you are using a RAID with LUN masking, you must make sure that the SANbox SSP port has access to the LUN.
