Using SAS drives for R710 PERC 6/i controller
I have a R710 server with PERC 6/i controller which originally had two 136 GB SATA drives and I want to replace them with two 500 GB SAS (Dell Constellation SED) drives. I put the SAS drives in slots 0 and 1, power up the server and the controller BIOS is reporting them both as failed. the top led on both drives flashes amber. The controller firmware is v6.3.1-0003, A14, as reported by the BIOS set up screen. While these drives are not new, I am wondering whether they had indeed failed or there is something else I need to do on the server to allow these drives to be used. Can anyone give me any suggestions?
Thanks, Daniel

No, you can't ... which is why I asked.
You can't disable it. The PERC 6 does NOT support SED - it has no knowledge of that feature, so it can't disable or otherwise manage it. There are no real "options" on the PD MGMT screen ... if they are showing as foreign, then you must first clear the foreign configuration on the VD MGMT screen (highlight controller, F2, Foreign, Clear).
If you don't have these options - no way to clear the foreign configuration and/or configure drives in a RAID array, then you probably can't use these drives on the PERC 6 at all. The H700 is supported in your server and does support SED drives, although I'm not sure what requirements exist for them.

Can you use the SED drives without encryption? The PERC 6 does not support SED's.
If you can indeed use them as "regular" drives, then check to make sure the drives are not showing as "foreign" on the PD MGMT screen.
Are you removing the 146GB drives and inserting the 500GB drives? or are you trying to "grow" your existing RAID 1 by replacing them one at a time? Are you sure about the "136GB" drive being SATA? Sounds like a standard SAS size.

Thanks for the reply.
You're right, the drives I had were 160GB SATA drives rather than "136GB". I are trying to replace the old drives all together rather than "grow" them one at a time. I don't think I can anyway since they are different drive types - SATA vs SAS.
How do I disable the encryption on the drive? I just want to use them as "regular" drives. I don't think I saw any options on the PD MGMT screen. The drive came up as failed and most options are greyed out.
Thanks, Daniel
