UNSOLVED
NS20 Backend Cleanup
I am trying to destroy the Celera Network Server and Reinstall. Before reinstalling the Celera Server, I am executing the following commands in order.
./clariion_mgmt -stop
unset NAS_DB
/sbin/service nas stop
./nas_raid -n ../bin/navicli -a x.x.x.x -b y.y.y.y -s cleanup
The fourth command which is supposed to destroy LUN and raidgroup fails with the below error. How do I resolve this error?
[root@EMC setup_backend]# ./nas_raid -n ../bin/navicli -a x.x.x.x -b y.y.y.y -s cleanup

Thank You Rainer. How can I resolve the below error.
[root@EMC-ATT sbin]# ./setup_clariion -init

Hi,
it means that the information about the IP adresses of the builtin Clariion is inconsistent.
It needs to be the same in DNS, /etc/hosts and /nas/site/cshosts as well as some internal databases that you cant edit directly.
Either it was installed incorrectly or someone tried to change IP adresses and didnt realize that there are other commands that need to be done to refresh the internal config databases.
PLEASE contact EMC customer service and let them help. Just tell them to look at Primus emc175031
The fix could be more complicated and really depends on your specific setup698

Thank You.
The earlier error "Array not clean, diskgroups remain 8" was resolved.
I went ahead with the fresh install, used Navisphere Manager to destroy Raid Group and LUN for the raid group 8 and then again did a fresh install.698

ok - after the new install you're supposed to use the Celerra Startup Assistent (CSA) for the initial config
also make sure you get the callhome config done properly and tested698

If you did it just for that reason than it was overkill.
You could have just removed the second 4+1R5 and the extra hot spares (after making sure they are no longer in use by any file systems or checkpoints), unbound the LUNs and created the new 8+1R5
The only reason to re-install would be if you need to change that first 4+1R5 to be changed where the DART OS is located - which isnt supported anyway.698

Rainer,
Yes, I did use CSA. The reason for reinstallation was I wanted to reset the RAID group as ATA_RAID5 4+1 HS_8+1 which was initially configures as
ATA_RAID5 4+1 HS 4+1 HS HS HS HS.
Is it always necesary to reinstall the NAS software to reset the RAID?
Thanks698

Rainer,
I tried to Unbind the LUN and destroy the second RAID using Navisphere manager but it was giving me the following error.
Navisphere:
Local Domain->CX310->Storage Groups->Celerra_emcnas_i0->LUNS->Right Click on LUN 19->Unbind LUN
"Contained Within a Storage Group"
When I execute Navicli Unbind command I get the below error.
[root@EMCMGR sbin]# ./naviseccli -h spa unbind 6 7 8 9 10 -o
Security file not found. Already removed or check -secfilepath option.
When I try to remove the raid group I get the following error.
[root@EMCMGR sbin]# ./navicli -h spa removerg 8
Error: removerg command failed
This RAIDGroup has LUNS in it. Unbind them and run removerg again.
I will keep your suggestions in my mind for future use.
Thank You698

Hello,
The error is becasue you didnt removed the LUN from the SG before trying to unbind. remeber that before trying to unbind a LUN you must removed from the storage group first then unbind the LUN from the RAID group.
yeah i know that you already solved your problem since this post is from feb.

please contact EMC customer service - your local customer engineer or NAS specialist should be able to help you out.
Ask them to look at Primus emc163849 and releated.
I assume you know that DART currently is not customer installable
