Free space of 3PAR is reduced after running tunesysOpen in a New Window

Hi,

We had a CPG with 8 SSDs of 920 GB (we also have FC disks). We recently added 4 additional SSD disks of the same size. After placing these additional disks to the system, the free space was 4356 GB (Figure 1).
Then we ran tunesys to the CPG (by the graphical console Action => Provisioning => Tune System, Tune CPGs ) and the free space was reduced to 3452 GB (Figure 2).

Why is free space reduced after running tunesys? I have the fear if I run the tunesys again the free space will be reduced even more.

Thanks in advance

How can I change the language in SSMC 3.0Open in a New Window

Hi Everyone,

How can I change the SSMC language from Chinese to English. I have re-installed the SSMC for a couple of times. In the setup, I always choose the English option, but after the SSMC installation. It is still Chinese....weird. And my Windows laptop is English too.

7200 Array Default IP?Open in a New Window

I'm getting ready to set up a StoreServe 7200 with a physical SP.  I'm looking at the documentation and it has me hooking a laptop up to the SP's networking port 1, configuring the laptop to a 192.168.0.2 address, and going to the setup webpage at 192.168.0.100.  So I'm guessing that the SP's default IP is 192.168.0.100.  It has me assign a permanent IP at this point.  

This is all well and good so far, but then we move on to setting up the storage system.  The documentation says in its prereq section to make sure that the SP and the storage array are on the same network.  I just assigned the SP a new IP.  I have NO idea what IP the storage array has, so how can I ensure they are on the same network?  Sure they will be in the same switch.  We don't have DHCP in this environment.  There was no network setup of the array prior to this step, so it would be in whatever factory default configuration is.

Did I miss a step where I do the network setup for the storage array?  I thought that was later when we run the storage system setup wizard, but the SP has to discover the system on the network before we can run that.  Chicken and the egg situation.  If by on the same network, they just mean in the same broadcast domain...then I think I'm good.

I have found a blog out there that describes connecting to the MFG port with the console user to setup the network using an undocumented secret password (that I found).  This can't be the official method of setting up the network since it requires an account that they don't even document.  I also don't have anything with a serial port in this environment to setup that connection.

So in the end my question is, what is the factory default network settings on a 7200 array?  How can I ensure that my SP will discover it on the network if I customize the SP's address as the documentation tells me to?  Is having them on the same broadcast domain sufficient?  Also I’m assuming this discovery process is happening over the Ethernet ports.

 

 

Can a 3PAR storage with file persona enabled do NFS with High Availability?Open in a New Window

Presently a 3PAR storage with two front DL380G9 servers acting as NFS with HA HIgh Availability. 3 volumes for  3 Exports to 3 separate VLANS. 

Can I remove the the two front end RedHat 7..2 DL380 servers acting as NFS with HA in place of only one  3PAR storage  with File Persona enabled?

I think that support and implementation wise it would be better than supporting and relying on RedHat,NFS HA and iSCSI. I see it as a week point as any change/upgrade/patch or OS bug on the Red Hat servers may effect the proper fuction of this topology and lately the 3PAR itself.

Any suggestion?

Remove a PD permanently.Open in a New Window

Hi Everyone,

IHAC want to remove some disks form 3par 8400.

I have some steps as below, which can dismiss the PD. But I still have some quries. So Thanks a lot if anyone give me some advice...

movepdtospare -dr 59                                           #assume the PD to remove is 59, dry run the movepdtospare
movech -perm 59:0-11:765 59:1-4:769 59:3-3:768              #move the chunks from pd59 to another spare chunks
showpdch -from 59                                              #verify there is no connection in pd 59
removespare 59                                                    #remove the spare chunks
dismisspd 59                                                        #successfully dismiss the pd 59

Then moved chunks are still in the spare space. How can I move these chunks to normal space?

how does the VV go into the undefined PD?Open in a New Window

Hi Everyone,

I have a question about the vv space allocation. The storage is 3par8400. It only has some SSD disks and 15K rpm SAS disks. Recently I add 6 10K rpm SAS disks in the ss8400, and I didn't do the tunesys job. Here is the question, I found the chunklets in the 10K SAS disks have been used.

So, I check one of the pd. Found there are VVs in the pd.

Here is the vv and cpg information. These VVs are in the FC_r5 CPG.

But the CPG in defined with only 15K rpm disks when creating. So how does these VVs use the undefined 10k PD?

SMB Share for Windows Roaming Profiles - Permissions IssueOpen in a New Window

Hi all,

We have HPE 3par Storeserv 7200c with OS version 3.2.2(MU4).

We have created an SMB share from file persona for a Windows VDI environment user profiles.

It was created successfully with everyone/full control share permissions and also we can access from client windows VM by //VFS/sharename/ but we are unable to change security permissions for shared folders. The properties security tab shows "Unable to contact active directory to access or verify claim types" message. And after selecting principal and setting permission for it does nothing. I also tried these using MMC, and there it gives error that "the specified group does not exist." And when I try to change owner, it says " the attached device is not working."

As an administrator we can create folder but other users cannot.

Let me know if you need any additional information.

Thanks in advance.

 

Perl REST clientOpen in a New Window

Does anyone test perl REST client ? I can run curl successfully, but fails through REST client. Tried user id and passwd, also encrypyted authorization Here is my sample code.

#!/usr/local/bin/perl -l

use JSON;
use REST::Client;
use MIME::Base64;

print 'Response status: ' . $client->responseCode() . "\n";
foreach ( $client->responseHeaders() ) {

Always get "invalid session key". same code works perfectly on Netapp's and EMC

Was wondering I have to pass the session key instead of username/passwd through REST client. But do not know how.

Trouble using Remote Copy and non-RC volumes at the same timeOpen in a New Window

Hi there.

Situation:

  • 2x 3par 7200 running synchronous remote copy for multiple volumes. Both systems attached to multiple Hyper-V clusters via FC fabric. Everything fine so far.
  • Exporting a VVOL from 3par-A (the one holding the active part of the RC-group) to the cluster works fine. VVOL is reachable from different (all) Hyper-V cluster nodes.
  • Exporting a VVOL from 3par-B to a single cluster node works fine. VVOL is accessible. Once added to the Hyper-V cluster, only this node can access it via FC (MPIO), while the other nodes report trouble and failback to so called redirected IO (i.e. accessing the volume redirected over ethernet via the one and only node that has direct FC access to it).

Goal: Have several VVOLs in RC and some non-RC VVOLs on both storages, in this case: get it working with 3par-B and the cluster hosts.

Any hints?

Thanks in advance. Timo

 

3PAR 7200 Upgrade IssueOpen in a New Window

Update of HP 3PAR OS 3.1.2 MU5 to 3.2.1 MU5 was performed. All preliminary checks were successful, but the final was unsuccessful: "All units are not online after waiting 45 minutes". Virtual Service Processor wrote that "Could not open connection to the CLI server process on the IP Socket connection timed out to port 2550". HP 3PAR Management Console also lost connection. In fact, the array does not listen ports 2550, 5783 and 5782.

But! SSH connection is working, the array is successfully updated, all the hardware components are error-free, production work fine, showalert/checkhealth/showversion ok.  

What is this error? What can be done?

Thanks

Update. The array listens to the ports: 22 (SSH), 5781 (Event monitor), 5988/5989 (CIM) and 8008/8080 (Web Services). And it's all!

RMC-V plugin for VMware?Open in a New Window

We are looking at using VVols with our 3Par7200 and vSphere 6.0.  The Best Practices Technical white paper mentions StoreOnce Recovery Manager Central for VMware (RMC-V), and says it can be deployed using the vSphere Web Client.  Where do I get the software to deploy RMC-V using the vSphere Web Client?  We don't have OneView for vCenter, so I can't deploy it that way.
