A maximum of 10 targets are supported in a BFS zone.

Call trace on sx2000

On an sx2000 system with the default logging level, a call trace may appear in the

Running scsi_info on XP1024/128

When running the scsi_info command on older XP arrays, such as XP1024/128, the output

similar to that shown in the following example may be seen. Ignore the error, and note that the

WWN is not all zeros.

The XP array returns inquiry data that differs slightly from that returned by EVA or MSA arrays.
