Ramifications of Enabling Space Reservation on Existing LUN

phs — Thu, 14 Mar 2019 13:41:01 GMT

Hello,

Hopefully my subject line covers the issue. I am new to NetApp and before I make this change, I am trying to understand the "what ifs". Currently the LUN is set to Disable space reservation, and there is live SharePoint SQL data on it. If I uncheck the Disable Space Reservation will it disrupt anything or cause any issues?

Thanks in advance for the information.

the CLI way is to offline the lun. though not sure via the GUI, but i'd guess it will blip it.

Take the LUN offline:
lun modify -vserver vserver_name -volume volume_name -lun lun_name -state offline
Set the -space-allocation parameter to enabled:
lun modify -vserver vserver_name -volume volume_name -lun lun_name - space-allocation enabled
Verify that space allocation is enabled:
lun show -vserver vserver_name -volume volume_name -lun lun_name –fields space-allocation
Bring the LUN online:
lun modify -vserver vserver_name -volume volume_name -lun lun_name -state online
