I thought I had deleted all my disk groups before created three new ones. Now I see the new ones as well as two ‘old’ ones.

Under Modify > Delete Virtual Disks the button Delete is grayed out. I’ve rebooted the server as well as the storage arrays. Because I’ve has multiple issues with disks I’ve put in quite a few new disks. I can’t imagine that these disks are doing anything if this group even exists at all.

*These disks are offline. I replaced multiple disks earlier before I created the new groups becasue of multiple disk failures. These disks will never come online. I need stop all activity and blow out all the diskgroups. How is this done?*

Under modify, can you get into the "edit mode" as suggested in the footnote below?  This may allow you to remove the old disks.  This is the only info I could find on your issue so far.

Modifying and Removing Host-to-Virtual Disk Mapping
You might choose to modify or remove a host-to-virtual disk mapping for
several reasons, such as an incorrect mapping or reconfiguration of the storage
array. Modifying or removing a host-to-virtual disk mapping applies to both
hosts and host groups.
NOTICE: Before you modify or remove a host-to-virtual disk mapping, you must
stop any data access (I/O) to the virtual disks to prevent data loss.
1 Stop any data access (I/O) to the virtual disks.
2 Click the Modify tab and then click Edit Host-to-Virtual Disk Mappings.
MD Storage Manager displays a list of virtual disks and the hosts to which
they are mapped.
3 Select the virtual disk you wish to modify by clicking its name.
4 To map the disk to a different host or host group, click Change located to
the right of the list.
5 To remove the disk mapping to a host or host group, click Remove located
to the right of the list.  }

Doesn't work I get the warning that the disk are inaccessible and may have been deleted - which is true.

I need to remove them as I've written because I can't do any Host to Disk Virtual Mappings as they are the only ones that show up.

I need to completely wipe the arrays of everything.

Hi xmouser

How did you get on with the MD3000 last night, have processes completed?

Can you now access the drives from your servers

Yes working. I'm still seeing the old diskgroups though that take up .5 Tb of space. I'd like to delete thos so I can reclaim the space.

I'm planning shutting everything down and move half the disks from enclosure 1 to E2, half from E2 to E3, etc. in an attempt to kill these 'ghost' disk groups.

Thanks for the help.

Have you gone into <Modify> <Replace Physical Disks> and reconfigured your RAID

This should identify the Virtual Drives as lost and allow you to delete them
