HP 3PAR problem Thin Provisioned VV unable to allocate SD space from CPG

 

Hello, I have a cabin HP 3PAR 7200 with firmware 3.2.1 MU1.

The systema storage is formed by the integrated controllers in which there are 24 enclousure 1.2TB SAS disks.

And a enclousure Disk 3.5 "3TB NL SAS.

The CPGs that are created are the default.

I am migrating an HP EVA8400 and VMware 4.1 with storage VMotion, and even when cloned VMs that are in the Datastores the 3PAR system, I get this error:

 

"Thin Provisioned VV xxxxxx SD Unable to allocate space from CPG yyyyy"

Re: HP 3PAR problem Thin Provisioned VV unable to allocate SD space from CPG

You should NOT be putting all of the same class drives in the same cage.

The default is "-ha cage" and since you have all in the same cage, you won't be able to allocate any space.

(Otherwise you need to use "-ha mag".)

 

If you haven't allocated any VVs yet, I suggest you start all over with a more balanced PD arrangement.

 

You can use showspace to see how much storage you can allocate, based on the type of CPG:

showspace -ha cage -p -devtype FC

showspace -ha cage -p -devtype NL

 

And retry with cage replaced by mag.

 

Or to list by CPG use:  showspace -cpg cpg-name

Re: HP 3PAR problem Thin Provisioned VV unable to allocate SD space from CPG

I don't think there's a choice.

Those NL drives look like 2TB drives, and AFAIK, the bigger NL drives only come in a LFF size. So he's stuck with HA Mag.

Ah right, he said 3 TB.  A showcage would show that.

So you need to create some new CPGs using "-ha mag".

If these are not the default FC_r* or NL_r6 CPGs, you can use "setcpg -ha mag cpg-name"

Re: HP 3PAR problem Thin Provisioned VV unable to allocate SD space from CPG

And, he wrote "The CPGs that are created are the default."

I am assuming it's one of those he's attempting to use.

 

The system won't create an inoperable CPG, so the FC_* and NL_* CPGs must already be -HA MAG.

So still not sure what the problem is.

 

 

Mainland, have you contacted HP Support and opened a case?

Hello, the cabin has this design has been carried out with the official tool HP NinjaStart

What I have seen is that if earlier in the CPGs in UNINIT appeared much information and was not zero.

(I assume you mean array.)

 

>showcpg

 

What does "showcpg -sdg" show?

 

>earlier in the CPGs in UNINIT was not zero.

 

Yes, with enough time the chunklets have been initialized.
