Adding used DAE's to CX3

Question

Hello, I've searched the forums, but haven't been able to find an answer to an issue I'm encountering. We have some DAE3P's that we're attempting to connect into our CX3-10c which were previously connected to another Clariion (I believe another CX3.)  The LUN's and Raid Groups were not properly removed prior to the DAE being removed from the system.  I've successfully connected one of the DAE's to the CX3 using the Unisphere Service Manager, but the DAE is showing a fault and all of the disks have an error on them in Navisphere.  When viewing the disks through the naviseccli they all show a state of 'Requested Bypass.' At this point I've tried everything that I can think of and don't see any advanced features in Engineering Mode that would help resolve this issue.  Does anyone have any suggestions on how we can wipe the config from the disks in these DAE's so we can connect them to our CX3 and use them? Thank you.

i guess it depends on the model of the drive (2GB / 4GB) , look on page 11 https://support.emc.com/docu42949_All-VNX-CLARiiON-Celerra-Storage-System-Disk-and-FLARE-OE-Matrices.pdf?language=en_US

not sure if that would help but you could try to zero them out http://emcsan.wordpress.com/2011/10/03/how-to-scrubzero-out-data-on-a-decommissioned-clariion/

that is interesting, unless it's a typo, CX3-10 does not support 300G 10K drives.

i am curious if your flare version supports those specific disks http://powerlink.emc.com/km/live1/en_US/Offering_Technical/Technical_Documentation/300-009-312.pdf

Thank you for the quick reply.

However, when I attempt the zerodisk I recieve "FRU not available for disk zeroing." I believe that this is because there were bound LUN's/RAID Groups that weren't removed from the old system so it wont allow me to zero the disk.

I appreciate the help, do you have any other ideas I could try?

Thank you again for the reply.

I think you may be on to something. I'm running a CX3-10c with flare 03.26.010.5.010 and the drives are the 300GB 10K 4Gb FC drives. If I'm reading the config matrix correctly only the 15K drives are supported, is this correct??? It seems odd to me that the 15K would be supported, and the 10K would not?

good, was the same part number listed under 2G and 4G support ?

ADailey · Answer

No, it was only listed under 2Gb/s support which is why I had to downgrade my backend bus... less than ideal, but I need to access these disks.

ADailey · Answer

Thank you for pointing me in the right direction.  The issue ended up being that I didn't realize these disks are a 2Gb/s disk which *is* supported by the CX3-10c.  I downgraded my backend bus speed to 2Gb/s and can now see/work with the disks to wipe them.
