PowerEdge 2950 recognizing only 2TB

I installed a 4TB SATA drive in a PE 2950 server on a PERC 5/I integrated card. The server recognizes only 2TB although I had the option to format it with GPT. The server is running 2012R2. What am I missing here?


Thank youj!

GPT is an operating system designation for disks, does not affect how hardware sees it. The PERC 5 and 6 are hard-limited to 2TB as the maximum disk size.

The firmware won't support a hdd that large. There is no firmware update or driver workaround.  sorry

(Actually, there is somewhat of a workaround, as long as the HDD is not an Advanced format (4k) sectored device.  One can have somebody reprogram the HDD firmware so that it reports it is 2GB in size.  You will only be able to use the first 2GB of the disk, but at least you will be able to use them.

My suggestion - if you bought the HDD from a retailer that told you it was compatible, get your money back.  There isn't any free software as far as I know that can reprogram the disk.    It probably isn't cost effective to send it out to somebody to do this for you due to shipping costs and the time it takes just to set it up, BTW.

Some have reported success upgrading the controller in the 2950 to an H700, which does support +2TB disks, which would be easier and probably more cost-effective than above :) The H700 is not supported in a 2950, but like I said, some have reported success (with some residual issues because the 2950 doesn't know anything about the H700, like there is a SAS cable warning that may or may not ever go away).

Or just buy an eSATA or USB-3 controller, cable and chassis.  This is just one disk, after all, not exactly a RAID5 config.
