HP StorageWorks HSG80 Enterprise Modular Storage RAID Array Fibre Channel Solution Software V8.8 for Sun Solaris Release Notes (AA-RV1SA-TE, March 2005)

ACS Enhancements and Fixes
20 HSG80 Enterprise Modular Storage RAID Array Fibre Channel Solution Software V8.8 for Sun
Solaris Release Notes
The addition of this new data provides additional troubleshooting guidance. See
the HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller
Software Troubleshooting Guide for additional information.
SHOW CONNECTIONS FULL command and additional screen display information
After entering the SHOW CONNECTIONS FULL CLI command, connection
details are now displayed at the bottom of the subsequent screen. Information
displayed includes maximum allowable connections, number of used connections,
number of free connections, and number of rejected connections.
Setting chunk sizes when initializing storagesets
When assigning chunk sizes with the INITIALIZE RAIDSET
CHUNKSIZE=xx CLI command, ACS now rounds up user-defined chunk sizes to
the next number that is evenly divisible by 8 to eliminate the possibility of
controller performance issues. Previously, controller performance under some
conditions were degraded when the chunk size was not divisible by 8.
Containers with user-defined chunk sizes created prior to this release function as
before. This change to the INITIALIZE RAIDSET CHUNKSIZE=xx CLI
command only impacts those containers created after the ACS V8.8-1 upgrade is
implemented on affected controllers.
Current units created with odd numbered cluster sizes still operate normally.
SHOW THIS or OTHER FULL CLI command and additional vendor ID information
ACS now displays vendor ID information for the controller after entering a SHOW
THIS CONTROLLER FULL or SHOW OTHER CONTROLLER FULL
command from a CLI prompt.
Disk Drive Auto-read-reallocate bit activation
Select disk drives use an auto-read-reallocate (ARRE) function that allows drives
to resolve recoverable errors. With this release, all disk drives with a model
number beginning with B (for example B00721937) implement ARRE
functionality.
Disk Drive SMART Error Handling
ACS now changes the configuration for the SMART (self-monitoring analysis
reporting technology) attribute on disk drives used in HSG60 and HSG80 array
controller subsystems. Configuration changes to disk drive SMART attributes
now support HP standards. SMART events are now only reported as recovered
errors and are reported to the host during normal I/O operations.
