Re: Autoraid 12H: normal or High Performance mode

According to the man page of arraymgr, Normal updates the controller maps on the disks at regular intervals (typically 4 seconds). This option offers both data protection and good performance.

HighPerformance updates the disk maps only during shutdown of the disk array. This is the lowest level of data protection, but it iffers the highest level of performance.

See the man page for more
# man arraymgr
To set the disk array to Normal,
# arraymgr -J Normal
To set the disk array to Highperformance,
# arraymgr -J HighPerformance

Hope this helps,
Never say "no" first.
