The NS20 has the ability to provide both block and file services through Celerra Manager and standard SAN block services through Navisphere Manager. You need to have purchased the optional Navi Manager license and the system needs to be set up via CSA so that the SP IP addresses are visible on the network through the Control Station. If that is all set up and you can point a brower at the SP IP address and open Navi Manager you can configure direct attach or SAN attach hosts via UI or CLI.
Having said that realize that you are then sharing the array between two paradigms NAS and SAN. Celerra Manager automatically sets up its own data structures on the array. The storage that supports Celerra File services look just like any other host when viewed through Navi Manager. Be sure the resources that you want to unbind are not supporting Celerra structures! If you unbind all LUN's without understanding what supports the Celerra data movers and control stations you may be headed for big trouble. Please open up a thread on the Celerra forum.

I am able to connect thru Navisphere Manager(NAT option, specify both Storage Processors IP's). I only have the 4 option under Navisphere,
1. Hardware Registration
2. Hardware Installation
3. Software Assistant
4. Hardware Maintainance

I could not find the option to unbind LUNs and create RAID in the Navisphere user interface. How do I find all the LUN numbers via CLI? Can someone list me the commands to execure the below procedure.
Unbind All LUN
Erase Old Raid Group
Create NEW Raid Group.select disk, Raid 5 DISK000-004, Raid5 005-0013, HS 0014
Create New LUNs.

Disk group info:
---------------------------------------------------------
Disk Group ID: 0 r5 Disks: 0_0_0,0_0_1,0_0_2,0_0_3,0_0_4
Disk Group ID: 8 r5 Disks: 0_0_6,0_0_7,0_0_8,0_0_9,0_0_10
Disk Group ID: 201 Unbound Disks: 0_0_11
Disk Group ID: 202 Unbound Disks: 0_0_12
Disk Group ID: 203 Unbound Disks: 0_0_13
Disk Group ID: 204 Unbound Disks: 0_0_14

I need to delete the second raid group(8) with hard disjs 6,7,8,9,10 and create a raid5 with the hard disks 1-14.

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.



Appreciate your response.

Thanks

Avilt,

is this unit already in production ? If it is, i would open a ticket and have support walk you through whatever that is you are trying to do without causing disruption or data loss.

No, system is not in production. No file system created. We can wipe out Raid. What is the command to list all the existing LUN's
Appreciate some quick response.

In terms of fixing the security error message, refer to Primus / Knowledgebase article emc149421.
Then you need to unbind the LUNs one at a time:
naviseccli -h ... unbind 0
naviseccli -h ... unbind 1
etc.
Once that is done you should be able to Remove the RAID Groups:
naviseccli -h ... removerg 0
naviseccli -h ... removerg 8
etc.

Thank You, could you please tell me the command to list all the LUN's. Also point me to the link of knowledgebase article emc149421.

You are using the Navisphere Service Taskbar, this a standalone tool. It is not Navisphere Manager. NST provides wizards which assist you in performing various tasks in teh categories you listed. NST work against all CLARiiON's even those integrated into Celerra. NT does not manage the CLARiiON.
