Available capacity for Thick Provisioned LUNs? They are all showing 0% free.

From the array's perspective a thick provisioned LUN is full so that is what most devices report to SRM. Generally speaking you will want to look inside the owner of the filesystem (server / VM) mapped to the LUN to understand how much free space there is available.

This is what I ended up Using:

SELECT 
s.Caption AS Array_Name,
p.DisplayName AS Pool_Name,
p.CapacityUserUsedPercentage AS UsedPercent,
p.CapacityUserFreePercentage AS FreePercent,
ROUND((p.CapacityUserTotal / 1.0995e+12),3) AS Total_TB,
p.thin,
p.DetailsUrl AS [_LinkFor_Pool_Name],
s.DetailsUrl AS [_LinkFor_Array_Name],
CASE
    WHEN p.Status = 1 THEN '/Orion/SRM/images/StatusIcons/Small-Storage_Pools_icon_up.png'
    WHEN p.Status = 2 THEN '/Orion/SRM/images/StatusIcons/Small-Storage_Pools_icon_down.png'
    WHEN p.Status = 3 THEN '/Orion/SRM/images/StatusIcons/Small-Storage_Pools_icon_warning.png'
    WHEN p.Status = 9 THEN '/Orion/SRM/images/StatusIcons/Small-Storage_Pools_icon_unmanaged.png'
    WHEN p.Status = 14 THEN '/Orion/SRM/images/StatusIcons/Small-Storage_Pools_icon_critical.png'
    ELSE '/Orion/SRM/images/StatusIcons/Small-Storage_Pools_icon_unknown.png'
END AS [_IconFor_Pool_Name],
CASE
    WHEN s.Status = 1 THEN '/Orion/SRM/images/StatusIcons/Small-Arrays_icon_up.png'
    WHEN s.Status = 2 THEN '/Orion/SRM/images/StatusIcons/Small-Arrays_icon_down.png'
    WHEN s.Status = 3 THEN '/Orion/SRM/images/StatusIcons/Small-Arrays_icon_warning.png'
    WHEN s.Status = 9 THEN '/Orion/SRM/images/StatusIcons/Small-Arrays_icon_unmanaged.png'
    WHEN s.Status = 14 THEN '/Orion/iSRM/mages/StatusIcons/Small-Arrays_icon_critical.png'
    ELSE '/Orion/SRM/images/StatusIcons/Small-Arrays_icon_unknown.png'
END AS [_IconFor_Array_Name]

FROM Orion.SRM.Pools p
JOIN Orion.SRM.StorageArrays s ON p.StorageArrayID = s.StorageArrayID

WHERE usedpercent > 80 AND p.displayname NOT LIKE '0000'

ORDER BY array_name ASC,
usedpercent DESC;
