Re: Enable space allocation command

Hello Paul,
thanks for reply. Prior to made any modification on the system i just wanted to be sure about the results. I had read the KB, and i've also picked up the Clustered Data ONTAP® 8.3 SAN Administration Guide (update 8.3.2, that is exactly our version).
And now i'm a bit confused: on page 41, "Enabling space allocation for SCSI thinly provisioned LUNs", the documentation clearly says for step 1 to "Take the LUN offline".
I fear that enabling space-allocation on an online LUN, even for CDOT series, still seems to be uncharted territory.
Can you give us a feedback about that?
Thak you very much

Re: Enable space allocation command

So, to avoid issues it's best to offline/online. If possible I would recommend a maintenance window to quickly flip the LUN.

Re: Enable space allocation command

Does not this option change information returned when host queries LUN properties? Which means for this option to have any effect host needs to rediscover LYN?
