What is the model of your Celerra ..there are models that do not support LUNs > 2TB (-2mb)

You can have 256 LUNs in a storage group, Celerra does not support MetaLUNs. How are existing LUNs sized ?

Hey Dynamox,

we are running Celerra NS40G with 5.6 version.... we already have 100 lun's in the storage group of clariion. I am not that sure how many lun's we can add in a storage group. Can i create 6 lun's and create a meta out of them and add it to celerra.

Some lun are 458GB and some are 500GB.  I have 2 big raid groups of 8254GB am not sure how many lun's i can create of that raid group. can you suggest me?

look again - 5.6.4 was never released externally

3rd number has to be 2 digits

no meta's

and stick to the supported RAID types and raid group sizes as documented on Powerlink

max. LUN size depends on your DART rev - older ones can only use up to 2TB

This is the full version of celerra 5.6.4. Am trying to add SATA disks.

To add - what is the full version of NAS Code - you mentioned 5.6 code - but we need to know full code to ensure that LUNs greater than 2 TB is supported by the NAS code running.

Also, we need to know what type of disks you are adding - are these FC or SATA disks?

There are certain guidelines for the RAID Group and LUN configuration - it depends on whether these are FC or SATA.

Thanks,
Sandip

it is 5.6.40-3

started with code 5.6.44.4 you can create LUN > 2TB on NS-960 as well as NS-40G, NS-80G, NSX, and NS-G8 NAS gateways when attached to CX3, CX4, and Symmetrix DMX-4 backends. So your LUNs have to be below 2TB, i typically take my raid group and divide it into equal size LUNs as long as they are below that limit. Make sure you adhere to these guidelines:
