How can I change va7xxx configuration?

#amdsp -a va7400
~~~~~~~~~~~~~~~~~~~~~~~~
RESILIENCY SETTINGS

Simplified Resiliency Setting:________Normal Performance (Default)
Enable Secure Mode:___________________True
Disable NVRAM on UPS Absent:__________False
Disable NVRAM on WCE False:___________False
Disable Read Hits:____________________False
Force Unit Access Response:___________1
Lock Write Cache On:__________________True
Performance Goal Configuration:_______Normal Performance

-----------------------------------------
I can see this result with "#armdsp -a".

Can I change "Simplified Resiliency Setting:Normal Performance (Default)" and " Performance Goal Configuration:Normal Performance"?

I need your help.

Thanks.

Re: How can I change va7xxx configuration?

armmgr -J
options are: SingleController, Secure, Normal, RestrictedNormal, HighPerformance.
The best performance/reliability level is achieved with Normal performance in which your disk array functions right now.
In normal mode maps are flushed to the disks every 4 seconds, in highperf - only on correct shutdown.
If you have performance problems I would check SAN (VA, switches, hosts) configuration first. The most common issue is SAN config, not 'internal' VA config
