I've inherited a CX300 that has been in production for several years. One of the drives in the array failed and the hot swap didn't engage. I deleted the hot swap and moved that drive into the slot where the failed drive was and the drive rebuilt itself.
I have ordered several replacement drives (same make/model as the one I pulled) and every time I insert one into the open slot the green light flashes a while (less than 90 seconds) and then the yellow failed light comes on.
I've tried using the Navisphere Service Taskbar to do the replacement I have a slot that's never been used so I tried to add the drive there (using the add drive tool) wirth the same result. The software claimed to have loaded the new drive but when I look the drive as shown as E.
Every drive I've tried (4 different drives as of now) shows up as failed. Is there a step I'm missing or do I keep buying failed replacements?
Sometimes an older drive is replaced with a compatible replacement disk (new model/firmware) - if parts is sending you a new drive it may be that the new drive requires a certain level of flare code to use the new disk. It may be that you need to upgrade the flare on the cx300 first, then try the new disks.
On PowerLink there is a Disk to Flare support matrix that lists all the disks and which flare version is needed to support that disk:
