SP Communication

if proxy-arp is enabled, you talk to SPs via the control station.

Depending on your model you should have a management port on the back of the control station or the SP's themselves. My NS-120 has a management port on the control station (MGMT) that then connects to the SP's. My old CX3 has a MGMT port on each of the SP's themselves. You plug into those ports and then open a web browser to connect to the SP IP addresses. The control station is a third IP.

I would recommend pulling the installation documentation for your SAN and reviewing it.

jsiergiej,

Are you fine with running a few commands from the Celerra control station?  If so, the following would help identify a few things:

/nas/sbin/clariion_mgmt -info

First two are obvious based on the name of the commands; however, the last one will let us know, in the case of an integrated unit (versus a gateway model), the Public IP addresses for SPA and SPB which should be assigned an IP address on the same subnet as the Control Station's mgmt IP.  For the out-of-band/management communication to either Celerra Manager or Navisphere Manager, in an integrated unit (via proxy-arp) all of that would be handled via the single network connection to the MGMT port on the Control Station, and is independent of the connections to the datamover front-end ports (CGE in your case).

Yeah, the installation for my NX4 has alot to be desired.  Basically, its "here's how you cable it" then "run the CSA".  I'm really disappointed with the documentation because it seems to me that alot of information is missing or skipped over so as to make it very difficult for someone trying to do the setup without the emc installation services.

Anyway, to set the IP's on the SPs and enable proxy arp, would this command be what I need? Keep in mind the SPs are still at the default IP settings:

/nasmcd/sbin/clariion_mgmt -start -spa_ip 192.168.254.91 -spb_ip 192.168.254.92 -use_proxy_arp

My control station is 192.168.254.90.  After I run this command from Unisphere, would I be able to access the SPs from Internet Explorer?

/nas/sbin/model -> NX4

/nas/bin/nas_version -> 6.0.40-5

/nas/sbin/clariion_mgmt -info -> Error 12: Not configured

Here is the info from the control station CLI.  Not sure what the Error 12 is about.

So to actually change the ip's of the SPs from the 128.x.x.x addresses they have now to the 192.168.254.x addresses I want to assign, would the command I specified earlier set them, turn on proxy, and allow me to access them?

Also, would I access them directly with their assigned IPs in IE or do I access them via Unisphere from the control station?

Actually – if you have run CSA properly it will have done all the work of setting up the SP addresses

As far a documentation – the printed one is really just there to get started. After that there is the service portal with how-to-do video’s and also the documentation CD

As a beginner – check out the wizards built into Celerra Manager / UniSPhere – they will do most of the common tasks

CSA errored on me on my first run through and I couldn't use it from that point on.  I set the IP of the control station and hit next and then it errored on me.  I could then access the control station from the network and get into unisphere, but I couldn't use CSA anymore because it won't detect the SAN.

Obviously, being that my CSA didn't run, I missed the part about setting proxy-arp on the control station and setting the SP IP Addresses.  Is there anything else that the CSA does that I may have missed and need to address?

I greatly appreciate all the help guys...

i don't think you can restart CSA from scratch now that you are some what configured. Did you look at the solution i posted earlier, it explains how to enable proxy-arp which changes SP's ip addresses.

well, when I run CSA and it gets to the detection part where it tries to detect the SAN, it says 'ERROR:Celerra not found.'  The first time I did it, it found the Celerra, but after I set the IP and proceeded to the next screen in the CSA, it errored on me and from that point on, I could no longer use CSA.

Is there a way to reset CSA or something on the Celerra so you can run through the CSA again and get everything covered or is that not a good idea if you have things like your SPs IP's already and your interfaces setup.  Not that it matters because this is not in production yet, obviously.

from memory ..it also sets up DNS, NTP ..you can also use it to setup CIFS/iSCSI.

you're welcome ..good luck.

Yep. it worked perfectly.  Thanks!   Glad to know I can get help from someplace.  When I call EMC support with a question on setup I get "Oh, you didn't get Professional Services?" and then the "We will have someone call you back" and no one ever does or if they do its 6 hours or even the next day.

Since CSA failed on me, its been rough to find the proper documentation in Powerlink about this stuff.  Tech support can't help me and even my contact at EMC hasn't gotten back to me with some information I requested.

Thanks again for the help!!
