How to check whether a celerra is Capable for Virtual Provisioning (VP)

virtual provisioning at file system level ?

You need to state which virtual provisioning – there are two kinds

File system virtual provisioning – its basically fs auto extention

There is no license or enabler needed

To find out if its used you need to look at each file system with commands like nas_fs if vp=yes

See the managing volumes and file systems manual on Powerlink for details

There are also virtually provisioned (thin) LUNs possible

Generally we don’t recommend to use these for Celerra file systems

You need an enabler which you can check with navicli –ndu –list

Then look at the LUNs if they are virtually or fully provisioned

What are trying to do ?

We are performing filesystem level virtual provisioning.

We have 5 Celerras, recently we add few EFD drives in 3 Celerra to configure VP.

I wish to know is there any command other than nas_fs -info to know that the box is cable for VP. Without adding EFD drives use of VP may not be that good I guess.

in order to use virtual provisioning on the back end storage you need use pool LUNs

Sorry – I don’t know what you mean

File system virtual provisioning has nothing to do with EFD’s
