Sun Storage 3510 FC Array - Version Not Applicable and later
A specific configuration of a Sun Storage 3510 FC Array might cause attached hosts to experience excessive SCSI timeouts, when a single host is rebooted.
If this occurs, messages similar to the following message appear in the "/var/adm/messages" file of the other hosts when one of the hosts is rebooted:
This issue only occurs when the Sun Storage 3510 FC Array is configured in "loop mode" in a storage area network (SAN) configuration with more than one host accessing the same Sun Storage 3510 FC Array.
The configuration affected by this problem is the "High-Performance SAN Configuration" mentioned in older versions of the Sun StorEdge 3000 Family Best Practices Manual
In such a configuration, if you have multiple hosts accessing the logical unit numbers (LUNs) for the Sun Storage FC Array, when one of the hosts is rebooted all the other hosts start getting SCSI timeouts and applications might appear to be hung.
