Re: E200i - Disabling array accelerator
AFAIK this message mean the content of the write cache, not the content of the logical drives.
Kind regards,
Patrick

Re: E200i - Disabling array accelerator
Patrick is right.
This message is referring to the data of the Battery backed cache only.
It has been tested, no harm would be done to the RAID configuration.
Well said that because RAID information is stored on the Hard Drives not on the Array Controller's Cache.
Happy Testing

Re: E200i - Disabling array accelerator
I was out for holidays..... :-)
The problem comes from the warning message that pops out when I try to disable the cache. Usually enabling/disabling or changing the caching algorithm (write through/write back) has no impact on data already stored on the array, then I don't understand the warning message (I don't remember it exactly, but sounds very intimidating about the possibility to loose data).
Although I managed lots of servers/raid controllers, this is the first time I got a similar message from a raid controller.
Obviously I can't accept the risk to loose data, so I need an absolutely "verified" answer....
