How to find LUN used space from ONTAP

baiju_cisco — Thu, 05 Jun 2025 05:55:01 GMT

Hi,

Environment having many thin provisioned LUNs (Linux) assigned to ORACLE RAC.

How can I find the LUN space usage information accurately from storage?

I do not want to involve DBA/host admin to find this information; how can I find this from storage/ONTAP CLI? Thanks in advance

Thanking you.

Hi ,

Are you sure that lun show -m and lun show -v can give the lun used space on the storage side .

lun show -m ----- lun mapping details to igroup

lun show -v -- detailed status of lun

can get some estimated used information using the "df -g volume name" if only one lun is provisioned on that volume .

Thanks

LUN show -v displays size, occupied by LUN, at least on recent enough DataONTAP.

I would be curious to know, what is the sense to post the same answer at three time...
