SD Cards are not RAID-1 paired

Hi,

I just start a new C220M3 with 2 SD cards. Right now, i can not use the SD card because i have the following status :

"SD Cards are not RAID-1 paired"

I do want to use the SD card in RAID-1 in order to install ESXi.

The CIMC version is 1.5(3d)

Please help.

Thanks.

SD Cards are not RAID-1 paired

delahais,

This is not something that has something to do with the RAID controller itself, this is something between the SD cardS which are NOT managed by the RAID controller.  Actually the name/definition of RAID is not like in disks, this is data that is synchronized between the SD cards but if one SD fails and you install a replacement, the data will not be synched up like disks do in a RAID 1 config.

To get rid of the issue, you need to load the SCU (Which can be downloaded from here:

Hi Kenny,

The FlexFlash was red and not orange (or green) ; the button "Configured Operational Profile" was offimg0.jpg

It was impossible to access to SCU.

I had to do a "reset configuration" :

in order to have an access to "the button "Configured Operational Profile" and switch  to status orange

after that, i could reboot the UCS to SCU and use Sync as you specified.

This white paper is very interesing to start with SD card  but it miss this piece of information.

Thank for your reply and all others ones in past !

Best regards.

Nicolas.
