I can create a new LUN with nine or fewer physical drives, however 10 or more fails. In either case, I still get a warning about the physical drives being different sizes.
Details of the MSA1000 drives, the offending command, and firmware versions are listed in the attached text file.
Are the 300GB drives supported on our current version of firmware? Or, is a F/W upgrade for the MSA1000 in my future?
Solved! Go to Solution.

> Logical Unit size = 3147116 MB
Apparently, you have hit the 2 TeraByte SCSI LUN limit. It's a 32-bit counter, so 2^32 (=4,294,967,296) blocks * 521 Byts/block = 2,199,023,255,552 Bytes.
You can put all disk drives in one disk drive array and put two logical disks into this array, but this will result in two LUNs which need to be combined on the host.

You can use the 14 300G drives. If using cli, you will have to explicitly call out the size.
Can you use the same cmd but add a size value.
size=2097151MB

Re: MSA1000 will not create new LUN with 300GB drives
However, the "WARNING: The physical drives assigned to this unit are different sizes.
If the unit is created, 10% or more of the total space will be wasted!" message I get when creating the LUN still concerns me.
Is this message valid? Is 10% of the total space really wasted? I don't recall getting this message when I created a 2TB LUN with 146.8GB drives.

Re: MSA1000 will not create new LUN with 300GB drives
For duplication, what is your MSA configuration. Are the 14 300G drives in the MSA1000 enclosure or MSA30 enclosure.
Run cli cmd>show versions
Supply this information.
Thanks,

Re: MSA1000 will not create new LUN with 300GB drives
I realize my f/w is probably in need of upgrading but I'm reluctant to do that because of the cascading effect of having to upgrade f/w on fiber switches, CASA, and HBAs.
Thanks.

You will need to upgrade your FW. Your current version 2.38 doesn't support the U320 EMU inside the MSA30 shelves.
