Dell 2950 Perc 6/i New drives orange amber light


I have two 2950 servers, PERC 6/i that are giving drive errors on brand new drives. All SAS. VMware VSphere test box.

I have a boot mirror of 146GB, those are fine.

I add a pair of seagate 2TB SAS drives and while initiating the VD in the RAID BIOS both drives flash the amber light. I do some test copies and place a VM on the mirror and it seems ok. The odds of two bad drives is small, but possible, so I set them aside and order two more. These do the same thing. Initialize ok but both flashing orange. I'm hesitant to use them in production. I can't beleive all four drives are bad.

The Perc utility shows the FW as 6.3.1-0003.

The Physical drives that are ok show
--:00:0x with x being the drive number. The two orange ones show
--:--:0x (middle segment being -- is the difference)

I tried this on a second, identical machine and it did the same thing.

Can anybody shed any light? My only theory is that these are not Dell blessed drives and perhaps they are not communicating properly at the PERC level.

That's possible, although SAS drives will "usually" work fine, regardless of whether they are certified or not.  What make/model are the drives?

They are Seagates:
Mfg. Part#: ST2000NM0034
CDW Part #3493591

Looks like that model is an SED drive. The PERC 6 does not support SED drives:

Do you know if there is a size limit (GB/TB) on physical drives?
PowerEdgeTechIT ConsultantCommented:
Yes, the PERC 6 is limited to 2TB physical disks.

Thanks again. I found some Axiom Drives that look promising. I really appreciate the help.

PowerEdgeTechIT ConsultantCommented:
I've never heard of Axiom, so I would have been wary, but they "promise" they work in the 2950 :) Just know that those drives are 6Gbps, but the PERC is a 3Gbps controller, so you won't get their advertised bandwidth, but they look like they "should" work.
bschatzmanAuthor Commented:
I hadn't either. They have an impressive line of memory and drives including SSDs. I wonder if it a relabel of another mfg products...

I'll let you know in a week or so...
