AVM system defined pool
Hi all,
last week i created a pool for file for a test purpose (because i had only 5 disk). Now i have installed other disks and i want to change the initial configuration from raid 5 to raid 6 but i can't because it is system defined pool. I have read some posts about this but i haven't found anything...can you help me?
Thanks

Hi Dinamox,
thanks for your answer. All disk are in use because is the first system pool created during the celerra installation.
I would re-install the celerra if is possible. I did this operation some years ago, but i don't remember which tools i used...
Thanks

1) validate that all file systems are gone and LUNs can be reclaimed (nas_disk -l ), column inuse should have an "n"
2) delete LUNs (nas_disk -delete -perm -unbind).
3) at this point you can re-create your raid group.

internal file systems should not be part of systems pool, my VNX5700. d7 is where my "data" LUNs start

is nas_disk output complete or did you chop it off ? So you created a pool on VNX, created a couple of LUNs and presented it to VNX datamovers ? If yes, then i don't see any pool LUNs presented.

Hi Dynamox,
the output of command is complete.
I don't have created any pool on CX, i followed the via wizard to configure the storage and the via created the pool.

can you post output from nas_pool -l
by the way looks your server_2 has failed over to server_3. You might want to look into it, it could a hardware issue or could be nothing and you just need to failback.

Just use /nas/tools/whereisfs –all to identify what is using what
