28 HSG80 Enterprise Modular Storage RAID Array Fibre Channel Solution Software V8.8 for Sun
Solaris Release Notes
22. Controller port TACHYON
chip malfunction
With earlier versions of ACS, controller port TACHYON
chip lock-ups occurred. Issuing the DISPLAY HOST
Virtual Terminal Display (VTDPY) command,
in some cases, reset the port. With this release, ACS
employs an automatic port reset.
23. Excessive abort messages
logged by the host
Under excessively high I/O rates, which included large
transfers, host systems occasionally aborted previous work
queued to the controller due to considerable controller
activity. This issue was further complicated by the use of
partitioned containers and path switches. With this release,
host systems initiate a fewer number of aborted I/Os.
24. Fibre Channel (FC) switch
goes port INSYNC state to
HSG
Prior to this release, resource leaks occurred if a controller
processed PLOGI frames against the rejected host list while
the connection table was locked. The controller would
report that all port conditions were Good. The FC switches
would report as being in the INSYNC state for connections
to one or more controller ports. Consequently, this
condition could not be cleared through VTDPY. This issue is
resolved with this release.
