Question on Potential Storage

Hello,

We are receiving the alerts.

"Alert A2:

Storage pool 'symm_std will fill its current  capacity on Dec 30, 2011 6:42:07 PM."

I have some confusion about Storage and Potential Storage in Celerra manager - Pool (sym_std) properties window.

It shows the following

Storage:

Capacity: 29.0 TB Used: 28.9 TB (99%) Free: 180.0 GB (1%)

Potential Storage:

Capacity: 36.3 TB Used: 28.9 TB (79%) Free: 7.5 TB (21%)

[nasadmin@PWC-US-ATL-CS0 ~]$ nas_pool -size symm_std -slice y

id           = 1

name         = symm_std

used_mb      = 30251703

avail_mb     = 184269

total_mb     = 30435972

potential_mb = 7647288

[nasadmin@PWC-US-ATL-CS0 ~]$

I have also tried to create a new file system (1 TB) to see if the space from Potential storage gets added to the Storage.

[nasadmin@PWC-US-ATL-CS0 ~]$ nas_pool -size symm_std -slice y

id           = 1

name         = symm_std

used_mb      = 31300279

avail_mb     = 118491

total_mb     = 31418770

potential_mb = 6664504

[nasadmin@PWC-US-ATL-CS0 ~]$

or

[nasadmin@PWC-US-ATL-CS0 ~]$ nas_pool -size symm_std

id           = 1

name         = symm_std

used_mb      = 737098

avail_mb     = 0

total_mb     = 737098

potential_mb = 6664504

[nasadmin@PWC-US-ATL-CS0 ~]$

any suggestions ?
