Hi,

I do have a cx300 storage and I need to find where FLARE installed? Is there a way I can find out? I want to clean up the some of the Raid group. I want to make sure that  I'm not deleting the FLARE.

To find out what FLARE code you're running, right click on the array serial number in Navisphere and select Properties. Select the Software tab. The version of FLARE is shown here. It will be in the format 02.nn.300.x.x - depending on exactly what version you're running. nn is the actual version number.

The FLARE code, along with a number of internal arrays structures, is in a hidden area on the first five drives. It's not possible to accidentally delete the FLARE code when you're manipulating RAID groups, so no need to worry on that score. Note though, that you musn't move the first five drives in the DPE as they contain the array boot partitions. If you muck about with them you will break the array .

You mean I shouldn't touch the first 5 drives? If I want to create raid group, I need to start to use from Disk 6 ?

No - you can use the first five drives. Just don't move them as they contain the array firmware structures. If you move the drives around, the array can't boot because it doesn't know where it's software has gone.

Best practice is to create a 5 drive RAID 5 set on drive 0 - 4. Don't exceed 100 IOPS per drive or Navsiphere performance will suffer. Also don't use the first five drives for snapshot cache or MirrorView Write Intent Logs. But you can certainly use the space on the drives for data.
