i don't see the 2TB LUNs ..Celerra either rejected them because of size or construct (number of drives in RAID group that comprise that LUN). Could be some residual entries left in the database, if i were you i would open a ticket with support so it gets cleaned up.

Hi Dynamox,
there were Two TB Luns added to SG (from SATA Disk) . I could see the 2 TB Luns.This was done sometime back by another person.
Is it b'cause somebody tried to add those 2 TB SATA drives and tried to scan for it ,but , it did not show up in celerra .
I see a clarata pool created from nas_pool , but no available storage.
How can i check if any of the disks from this are in use ?
Also, It's showing LUNZ error( not sure of that)?
Thanks for having a look at it.. please suggest.

Thanks Dynamox,
I get this figured out-
It's a SATA Raid 5 configuration:6+1 RAID 5 or 4+2 RAID6 or 8+2 RAID 6 on SATA drives.
And in my Raid Group i see it created as 4+1.There are other people working on this, and some body had tried to carve luns from this configuration and present it to celerra.
I think i can fix this now in case thid doesn't will call for a service request.
Thanks!!!
