Unable to delete former Celerra LUNs on underlying Clariion
Hi all,
I'm currently facing the following issue:
On a customer System I have two LUNs on a Celerra NS-120 presented from the underlying Clariion System. I deleted the mounts, checkpoints, filesystems and disks (automatically removed the Raid Group).
Now I removed the Data LUNs from the Storage Group on Clariion. Worked fine. After this I tried to delete the LUNs but Unisphere indicates that one of the following prevents the LUNs from being deleted:
1. Storage Group
2. Mirror
3. etc.
Checked twice on Unisphere if the LUNs are still part of any of the listened Operations but there is no indication for this.
Is there any other way I can Check if the LUNs are used by one of the Operations or is there some way to "force" delete the LUNs on Clariion?
Thanks in advance. Kind regards,
Tim

Hi Tim,
If you have the cli installed would urge you to run the command :
naviseccli –h getlun
obtain the getlun output for the private luns (“List of LUNS”).
If the mentioned lun number shows still as a pvt lun then shoot :
naviseccli -h x.x.x.x -user -password -scope 0 getlun - 19 -stack
If any of the below drivers are listed means that the lun is in a stack and needs to be released
Listed Driver: K10RollBackAdmin
K10FarAdmin
K10SnapCopyAdmin.
To relese : naviseccli -h x.x.x.x -user -password -scope 0 mirror -async -setfeature -off -lun
Please reply with the getlun output.
Thanks

Can you verify 'nas_disk -list' command output.

[root@sag-celerra-01 nasadmin]# /nasmcd/sbin/naviseccli -h SPA getlun 18
Security file not found. Already removed or check -secfilepath option.
[root@sag-celerra-01 nasadmin]# nas_disk -list

In Unispehre the small Thumbnail in front of the LUN Name divere from the picture shown for "normal" LUNs. Find attached a screenshot. LUN200 and LUN201 are the LUNs I removed from Celerra.

Hi guys,
finally found the solution... double checking the mirrors wasn't enough. Found a remaining mirror for the LUNs...
Thanks for your support.
Regards,
Tim
