Oracle’s Sun Storage F5100 Flash Array with SATA FMods has the potential for SATA affiliation conflicts. Conflict can occur when more than one initiator tries to access the drive via the same SIM or Controller path (i.e., more than one host attached to a F5100 array domain).
Possible symptoms of SATA Affiliation conflicts are: operating system hangs, zoning operations take longer than 10 minutes to complete, and/or disk utilities like format will not return device lists in a timely fashion.
When more than one instance of Sun Storage CAM probes a SATA FMod from a single SAS domain, SATA affiliation issues occur which lead to possible symptoms as stated above. For this reason, connect only a single Sun Storage CAM host to a SAS domain unless drives have already been zoned to prevent SATA affiliation issues. After the access configuration (zoning) is completed from a Primary Sun Storage CAM Server (or a Primary Sun Storage CAM Server with only one active proxy agent), Sun Storage CAM can be installed or enabled on additional proxy hosts as desired.
