Problem making new NAS POOL
Ok, I'm confused! As per a previous posting, I got in a tray of SATA drives, created a couple 6+1 Raid 5 arrays, created a couple LUNS, and dropped them into my CELERRA Strorage Group. In Celerra Manager, a new system defined clarata_archive pool was created but no volumes.
From the Celerra CLI:
[nasadmin@celerra2 nasadmin]$ nas_pool -list
id inuse acl name
3 n 421 clar_r5_performance
4 y 421 clar_r5_economy
10 n 421 clarata_archive
Doing a nas_disk -l shows:

19 y 547418 APM00060504673-001C CLSTD d19 1,2,3,4
20 y 547418 APM00060504673-001A CLSTD d20 1,2,3,4
21 n 511999 APM00060504673-002A CLATA d21 1,2,3,4
22 n 511999 APM00060504673-0029 CLATA d22 1,2,3,4
If I try to create a user defines pool with these drives I get:
Error 3147: volume d21 resides on a reserved disk
So, how do I get these volumes in a pool I can use. I appreciate any help you can give on this.

As a review, I created two, 6+1 Raid 5 groups on one tray of SATA drives. I then created 2 LUNs of 500GB each, one on each RG. I then dropped the LUNS into the Celerra Storage Group that already housed a clar_r5_performance pool. I expected to be able to see these LUNS on the Celerra and then create a user defined pool. However, doing a nas_pool -l then showed a system defined clarata_archive pool. This pool info shows:
id = 10
name = clarata_archive
description = CLARiiON RAID5 on S-ATA
acl = 421
in_use = False
clients =
members =
default_slice_flag = True
is_user_defined = False
volume_profile = clarata_archive_vp
is_dynamic = True
is_greedy = True
I can't create file systems and can't add the disks to the pool. The nas_disks show as:
19 y 547418 APM00060504673-001C CLSTD d19 1,2,3,4
20 y 547418 APM00060504673-001A CLSTD d20 1,2,3,4
21 n 511999 APM00060504673-002A CLATA d21 1,2,3,4
22 n 511999 APM00060504673-0029 CLATA d22 1,2,3,4
So the Celerra sees the volumes of the right size, but they are not in use.
I hate to have to place a support call if I can get find the key to getting these devices associated with this, or a user defined, pool. Any help is appreciated.

The issue was the HostID. When the LUNs are added to the Storage Group, the HostIDs are assigned as the next available, and since the HostID field is positioned off the right side of the window, it chose IDs lower than 16. After the LUNs were removed from the Storage Group and then added in picking an available ID above 16, a devconfig was run and the Clarata_archive Pool now has the space available. My mistake was not recognizing the LUN vs HostID number issue.
I take no credit for finding this. One of our local EMC CEs, Steve Hoes dialed in and found the problem. So, thanks to him and all of you other respondents. But the documentation on Storage Pools still pretty much sucks.
