Enhancement Description
RAID 0 RAID 0 provides improved performance but without data protection.
RAID 0 provides no data redundancy and should only be used for
non-critical data. The loss of a single disk in a RAID 0 LUN causes
the loss of all data in the LUN.
Major event logging Provides greater depth of information on disk array events. This
information can improve efficiency when isolating problems. Major
event logging logs more types of events than standard logging used
on earlier versions of firmware. Major event logging is enabled using
the UTM. For more information, see
"Managing the Universal
Transport Mechanism (UTM)" on page 322 .
Performance data gathering
and viewing Performance data can be gathered and analyzed to determine if the
disk array configuration settings can be tuned to achieve better
performance. Because of the complexity involved in interpreting the
data, customers should not perform this task. For more information,
see
"Gathering Performance Data" on page 329 .
-force option added to amutil
syswipe command The -force option formats the disk array even if there are LUNs on it.
For more information, see
"Reformatting the Disk Array Media" on
page 331 .
-rr option added to amutil
command The -rr option changes the status of a disk drive to REPLACED. For
more information, see
"Changing Disk State" on page 336 .
amlog -t -mel option added The -mel option displays major event log contents. For more
information, see
"Viewing Disk Array Logs" on page 341 .
