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 storage-side fabric is correct.
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 0-255 only.
■ 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 5-6 for more
information.
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 B-19 for more information about this
command.
■ Zoning of storage-side fabric is correct. See "SAN Zoning" on page 5-3 for zoning
tips.
■ 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.
