Aggr/Flexvol Question

[natrian_maxwell]

I am using the data ontap 7.3 simulator and

I have come across an issue. Whenever I try to create a flexvol in an aggregate I am getting an error message.

Netapp> vol create flexvol1 aggr1 1g
vol create: Containing aggregate 'aggr1' was not found
Netapp> aggr status
           Aggr State           Status            Options
           vol1 online          raid_dp, trad    
           vol2 online          raid_dp, trad    
           vol3 online          raid_dp, trad    
          aggr1 online          raid4, trad      
          aggr2 online          raid4, trad      
          aggr0 online          raid_dp, aggr     root

What am I doing wrong?

I also tried aggr2 and got the same error message.

Can someone help?

aggr1 and aggr2 are traditional volumes not aggregates. You cannot create FlexVol inside a traditional volume.

aggr1 online          raid4, trad      
aggr2 online          raid4, trad      

They are traditional volumes and not aggregates. The message is shown " vol create: Containing aggregate 'aggr1' was not found". If you try commands "vol status" you will aggr1 & aggr 2 shown in that list too.

Your aggr0 can be used here.

What is the difference between a traditional volume and a Raid Group ?? i got the below commands,

## create traditional volume using aggr command

aggr create tradvol1 -l en -t raid4 -d v5.26 v5.27

## create traditional volume using vol command

vol create tradvol1 -l en -t raid4 -d v5.26 v5.27

The traditional volume is not let us create a FlexVol on it even,Could someone throw on some light on it ??

trad vol are fixed..

flex vols can be increased or decreased on fly.

we used to create trad vol way long back, but now a days you hardly see them.. most of the volumes are flex vols...

you are mixing stuff together

keep this hirearchy in mind:

disks --> raid groups --> aggregates --> volumes --> qtrees / luns
