HPE Storage Users Group

hey guys,

i´ve got a question about the OOBE about a 3Par 7200/7400.
We have here an old 3PAR in the company witch we wan´t to use
as a DEV system or just only for testing etc....

The system is a: 7200/7400 with 2 controller, each controller
has a 10GbE nic ( i think it´s a CNA ) and we have 2 additional
storage boxes with 24 x 900gb FC drives.

I have the password from the 3paradm so i think this is a good way,
i can log in by using the management software and can create virtual
volumes and everything but the system show that there are problems
with the admin volume and the PR Volume i think.

i´ve tried to change the ip address to the we want to use in the
dev/lab network. I´ve logged in the mgmt software but here i´cant change
the ip because the software shows somting like "verifying" so i tried to do this
by the cli via the setnet command and here i get the message the the admin
volume is not reachable.

So i was reading / searchin in the internet and i find out that there is a oobe mode
for the system.
What happend if i use the oobe ( serial connection etc.... ) the system is fresh ? What
happed with the installed license ? Did i need to reactivate all my features and disk witch
are currently licensed ? Is there a option to backup and restore the license after the oobe
procedure?

Maybe i don´t need a oobe precedure. maybe some one can help me:-)

If you need additional infos please let me know i will post it

There are a few errors there, but the one that is probably causing problems is:
Network Too few working admin network connections 1

Do you have both nodes plugged into the network, When changing the IP it will try to verify that the network for both nodes is ok.

I will probably be carrying out the same type of procedure in a month or 2 on our 7200.
If you do a reset, you will probably need to install the licenses again, you can get them from the HPE portal again.

thanks for you response

i´ve connected 1 7200/7400 with both controller connected
the other system is not connected to the network. Must i connect
it to the LAN ? Should i connect the RCIP ports also to the LAN ?


My plan is to use the other System as a training system only and not in the current cluster.
Can i change the cluster config so the i have not a cluster ( i mean the it is not a 7400 but 2 7200 systems )

The one node has 192.168.1.10
and the other 10.0.1.6

I want to reset the 192.168.1.10 to 10.41.x.y but it dosen´t work.

Is it not possible to export and import the license because the cli has this option for export
and i get a file like
1324-234-1234-1414
4678-4567-5698-890
.

1384-234-2341-1232

i hope this are enough infos

greeting and thanks

You can use the "showlicense -raw" output as the license for adding to the system again.

Was it a 7400 that you have split up, or was it actually 2 x 7200 (7400 is essentially 2 x 7200 with a link cable between them and a BIOS change).
Im guessing you are using
array: 10.0.1.6
gateway: 10.0.1.1 ?
ntp: 10.0.1.10 and 11 ? (I just randomly picked 2 addresses for example, change as it should be)
dns: 10.0.1.10 and 11 ? (I just randomly picked 2 addresses for example, change as it should be)
name: testarray1

you would do the following:
Ensuring that you have both nodes connected to a switch on the correct vlan and can ping the gateway.


Is this what you did?

Hey david

thanks for you replay.

I´d know exactly if this was config as a cluster but i think so. Is there any way ( by the cli or similar) to check this ? My colleague say´s that it was not clusters but it looks like it was a cluster because i have 4 of these HPE special link cables. But there are only 96 disks licensed so from my opinion it can´t be a cluster because there a not enough disks in for a cluster
Is there any way to figure it out by cli oder mgmt software ?

If i try to change the IP i get the following



With the license -raw i have exported my licenses already.
Maybe it helps is you know what is all licensed
This is all active for 96 Disks

Reading the output of checkhealth, you have more than one problem on hand.... Doing a back-in-the-box and out-of-the-box will not fix your SAS cabling issue.

It will not fix missing cabling/zoning issues resulting in host not seing more than one node.

It will not fix the lack of physical network connections to the nodes. (Network -- No nodes have working admin network connections)

It will not fix the unbalanced of physical disks.

It will however start the system up again with the health drives you have (from what I can see, multiple drives has failed in the system and probably been yanked from the system).


So I would fix those issues first, then do OOTB.

If you're unable to re-use the license key exported thru showlicense I would try and log a support case. As long as you are the original owner of the 3PAR system I would be surprised if they didn't provide you with the registered license for that system even if there is no support contract.
