Removing DAE's to have more space..

Hi All,

We have a cx3-80 which is at the DR site and the box is out of space.We are not able to expand the file systems .We already have 32 enclosures and 480 disks . So there is no option to add another SATA DAE.

Could you please suggest me what is the option to over this come this situation ?

1. Can we completely remove all the drives in a particular enclosure and then add new higher capacity SATA drives ?

If so can you please suggest how to acheive this as this is an emergency situation  .We are not able to expand any file systems.

Re: Removing DAE's to have more space..

i can imagine you could take 1TB SATA drives that comprise a particular raid group, delete LUNs that reside on that raid group, delete raid group itself and replace the drives with 2TB SATA drives. If you are going to do that, think about the hot spare too ..as you will need one to spare for 2TB drives.  Are these LUNs used by Celerra ?

Hi Maddy Krish,

You can perform drive upgrade!!!

Make sure Enclosure Chassis Part No. support 2TB SATA drives…

Check 2TB SATA Drive Support with your current FLAIR version…

Number of HOTSPARE per drives… if you are upgrading only one enclosure then 1 HS is sufficient…

Thanks,

Re: Removing DAE's to have more space..

We have 32 enclousres and cx3-80 will only support 32 enclosures and 480 drives

All the slots in all the enclosures are all populated with drives and there are no free drives on this clariion  will CX3-80 support 2 T B drives ?

you can either remove all 15 drives, or just the drives that make up one raid group. In order to remove drives, you have to delete the raid group, LUNs that reside on that raid group ..so yes ..all data will be gone. If this is a Celerra unit you have to be very careful, better call EMC support if you are not sure.
