Tunesys after adding new disk and Physical disk usageOpen in a New Window

I have a 3PAR with 12 SSD disk and with 1 Virtual Volume 4TB with Thick provisioning created. Recently we bought another 12 disk to expand the capacity. After adding the license and disk initialization, I perform the tunesys with default setting. I have also provision a new Virtual Volume 2TB thick provisioning. But the allocation percentage of each disk is not balanced. The existing 12 disk allocation percentage is still very high and the new 12 disk allocation are not balanced up. 

What tunesys option I should tweak in order to balance the allocation percentage of each disk?

I also found out the not all the phsyical disk are used. The new Virtual Volume although is exported to Host, but it have not start putting data or files to the new Virtual Volume. 


Automatic Sending of HP 3Par command through email - scriptOpen in a New Window

Hi, sorry as I do not know yet how to categorize may inquiry correctly in the location.

I am new to the HP Storage Environment and I just would like to ask if you can help me with a task.

For example, the output of a command showrcopy from HP 3PAR be sent to my Outlook email at 6:00 AM GST?

May I know the tools that can be used to achieve this?

Thanks for your time and assistance and help will be all appreciated.

3par 8200 change SparingAlgorithm - possible online?Open in a New Window

my current config:

3par 8200 / 2 cages / 10 ssd + 38 fc. (cage0 20 FC/ 4 SSD - cage1 18 FC / 6 SSD)

Sparing algorith: maximal

So, now I have only 8 usable SSD disks with 2 spare.

I think, if i change sparing to minimal, i have an additional usable SSD... Is it true?

I found a manual to change sparing:

I can do this changes (setsys + admithw) online? How long does it take about?


thank you / best regards



Reclaim space, problem with chunklet links?Open in a New Window


As many others we are having trouble reclaiming space in our 3Par 7200c.
We are running ESXi 6 and some physical Windows servers.

We had higher hopes on the deduplication ratio on the 3Par, (we are at 1.4-1 with 16kb cluster size) but we have gotten used to it being low so it doesnt bother us so much anymore.

But because of the low ratio we bought 2 cabinetts with FC drives. We wanted to move servers to those drives that doesnt need the speed of the SSD drives. About a month ago we moved about 6.5TiB data to the FC drives so that we could get more free space on the SSD drives.
We moved virtual servers in our VMware environment. We have been running unmap and everything else one can think of (compact CPG, Tune System), but after more than a month we only got back about 1TiB when we wanted to get back 6.5TiB.
The 3Par console shows the disks that we freed to be 0% used, but still when highlightning the SSD CPG we only see that we have gained back 1TiB.
We decided to delete one of the virtual volumes and force 3Par to give us back the space, but even after deleting a volume we knew had contained 1.5TiB data we got nothing back.

We are starting to think there might be some problems with the chunkstore. I heard somewhere that there could be a bug in the chunkstore, something about the chunkstore not deleting unused chunks. Anyone know about that?

About reclaiming space, has anyone found any difference in the amount of space you get back and the time in which you get it between running Thinly deduped and Thin Provisioning?

We are thinking about moving away from using Thinly deduped and only using Thin Provisioning in hopes that we shall be able to reclaim space easier and also know how much space we have left.
But we cant go that way as it is now because moving data to Thinly provisioned disk and not getting anything back from the deduped volumes makes us run out of space.

3par replaced node cannot join clusterOpen in a New Window


I had a 3par 7400 with 17 enclosures and os version is with 1 faulty node(Node0). I tried to replace it with a used controller as a spare, after replacement the controller led become steady green which means it couldn't join the cluster. so we tried to shutdown the cluster and powered off and on the box base on the documentation. after power on the 4th node (NODE 3) also become faulty and dead. so after a quit long time we tried to change the 4th node (Node3) base on replacement document, same as Node0 happened to it. I tried to wipe out the configuration and I did the deinstallation the system but still the Node1 and Node2 can joined the cluster. then I tried to rescue both nodes one by one since both have already used in some other systems and rescue actually finished successfully and the have got correct box serial number and hostname but still they couldn't join the cluster and their interconnect ports are amber.

please help

thanks in advance

Rebooting 3par nodeOpen in a New Window

I have a 3PAR 7200C with physical service processor. The OS of the 3PAR is with P17 and P18. I would want to perform a node reboot for our datacentre redundancy testing. 

I login to the service processor, but the reboot node drop down list option seems to defer from the usual. The normal drop down list option will have "node 0,Node 1 or Node All"  but this dropdown list shows "Node spcomm_get_node_list,node failed,node in,node clusternodelist and node all"

Why the drop down list option differs?



3par use space simple questionOpen in a New Window

Hi guys,


I'm new with 3PAR and got a really basic question.

We recently started feeding the VMs hosted on the 3PAR SAN, and we’ve discovered something interesting regarding the storage efficiency. The servers themselves appear to be optimizing the data stored far more than we expected. Normally, it uses about 2TB of the 3.5TB of space in the system. Right now, the drives are only using 1.3TB yet they still appear to have the same files available. Is this the block-level optimization mechanism that was mentioned as a part of the 3PAR SAN? If so, how often does this optimization occur?

Thx !
