Symptoms

I/O to drive(s) in an Sun StorEdge A5x00 Array subsystem becomes unresponsive or incurs retryable SCSI errors on a Solaris host.
In most cases, this is a hardware fault. In general the design of FC-AL(Fibre Channel Arbitrated Loop) allows participants of the loop to corrupt, or fail to pass packets to the target of the I/O. This is much like a TCP/IP token ring configuration, in that if one system fails, the rest of the ring cannot communicate.

 

The command "luxadm probe" shows individual drives instead of the SES devices for the IB's
