HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution Software V8.7A for Windows Release Notes (AA-RH0QL-TE, July 2003)

New Features

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

Software Version 8.7A for Windows

• Linked WWIDs for Snap and Clone Units—To better manage snap and clone

unit creation, a linked WWID scheme was implemented. It keeps the WWIDs of

these units constant each time they are created. The linked WWID scheme reduces

the number of system data records needed to track unit WWIDs, and enhances the

stability of administrative scripts used in unit creation.

• SMART Error Drive Eject—In prior versions of ACS, SMART error

notifications received from a device were treated as soft (recovered) errors. The

notification was passed to the host and operations continued. ACS now provides a

CLI switch (SMART error eject state) that offers an alternative to this behavior.

With the new switch enabled, drives in a normalized and redundant set that report

a SMART error are removed from that set. SMART errors reported by drives in a

non-redundant or non-normal set continue to be treated as recovered errors. If the

switch is disabled, all SMART errors are treated as recovered errors.

• Error Threshold for Drives—ACS now provides the ability to set limits for drive

errors. Once the limit is reached, the questionable drive is removed from any

redundant set it is a member of and put into the failed set. Errors counted are

medium and recovered errors. Hardware errors are not included in this count since

the drive fails immediately when a hardware error is encountered.
