MSA P2000fc G3 shows as a L port status.

Hi, firstly im no expert on SAN's and the new P2000 G3 and am haveing some issues being that in the switches the P2000 shows as a L port status.

I would like to have a F port status so I can zone them via aliases (as i have done with my msa 1500's in the past), is this what I should be doing or should I use port zoning for the L ports?

I realize L ports are loop and F ports are fabric but I don’t understand the fundamental difference between the two?

I have updated the firmware on the P2000 but have not yet updated the firmware on the san switches as yet but this is my next step.

Any help/advice greatly appreciated.

Best Regards
Iain

Hi, definitely give updating firmware on the SAN-switches a shot.

But maybe you could also check the setting you have on the host port in the P2000 SMU?

One setting is supposed to be for a direct-connected server and the other for a SAN-switch. I believe the one for direct-connect will turn the port in the P2000 into an L_port so that it can have a little loop with the server.

After you set it I would restart P2000 and SAN-switch.

WWN-based zoning (using aliases or not) should work for L_Ports, too.

I know when I first got my MSA P2000fc G3 the ports showed up as L ports. I switched them to F ports. I think I did it on the SAN switches.

Re: MSA P2000fc G3 shows as a L port status.

yeah, you can see how they are configured with 'portcfgshow'

maybe there is a portcfgfport command you can use

Re: MSA P2000fc G3 shows as a L port status.

Hey, OK so your right I can alias a L port thanks for that ;) when I first check it was not allowing me to add it in SwitchExplorer GUI.
I have now zoned and am waiting for a downtime to reboot the cluster nodes attached to the SAN to see if they pickup the MSA200o and I see it in the ACU.

I have x 2 SAN switches so I have set one of the MSA2000 ports to only allow that of a F port status and autonegotiate for the speed and now it shows as a F port and a message of IN_Sync as oposed to ONLINE I think this is a misconfig between the SAN and MSA ports?

I also do everything via SWITCHEXPLORER GUI not via the hyper terminal.

I guess another question is what is the difference between F adfn L ports in there functionality and how will it effect perfomrance?

As I sai im no real expert on this....the MSA1500 just seemed to work ;)

You dont have to use hyperterminal, you can use putty as well and connect via telnet/ssh.

What is the setting on the host ports in the SMU?

Re: MSA P2000fc G3 shows as a L port status.

OK cool good to know I can do it over IP as oposed to serial but I still dont really know all the commands so still mainly ues the GUI (still a newbe).

SMU ? Is this the sys mangemnt utility (web front end) on the MSA 2000 ? If so I had a look but could nto find the settings for the ports, where are they ?

If you need me to run any commands please tell me them ?

Re: MSA P2000fc G3 shows as a L port status.

OK.Rebooted under a CM and I dont see the MSA2000 ??

One thing I should have mentioned is I My 2 servers are connected to the SAN's useing 1 FC cable each, now this cable is currently zoned with a MSA 1500cs attached to it and I have zoned the MSA2000 to this also So can I attach another controller to this or does it have to go into its own FC HBA ?

The HBA's I have in the servers are luckly 2 dual port HBA's in each server giving x 4 ports so I can cable each server to both of the SAN switches twice giving redundency ?

Any help massively appreciated!! ;)

Re: MSA P2000fc G3 shows as a L port status.

The MSA2000 / P2000, host connection is set as Loop, from factury. Simply change it to: point to point.

You can do that from the gui or from the CLI, via telnet. Whatever you prefer.

Hey thanks for the info I will change to point to point.....

As to my question, can I have a MSA1500 and a MSA2000 both connecting to 1 FC HBA on the same server ?

So Say:
port 0 FC HBA 1 on server
Port 1 FC on MSA 1500
Port 2 FC on MSA 2000

Zone 1 Port 0 and port 1
Zone 2 Port 0 and port 2

Config: Zone 1 and Zone 2

(I have more devices attached but this is a simplified version of the question)

Will you see both controllers in the HP ACU on the server as expected and required to configure?
At present port 2 is set to a L and I think this may be the issue ?

Many Thanks

Hi!

No, the MSA2000 will not show up in ACU.
You do all the configuring via the MSA2000 web interface.

Yes, do configure one HBA-port and one storage-port per zone. Brocade's recommendation is 'one initiator and one target' in each zone.

Re: MSA P2000fc G3 shows as a L port status.

Hi, Thanks again!

So am I correct in thinking that 1 single port FC HBA on a server can have 2 different MSA's connected to it (as with the zoneing and config I described ?)and the server will see them both ?

Also is the selective storage presentation configured in the web front end of the MSA 2000 also.

As said, the P2000 will not show up in ACU.

The "SSP" for P2000 is most easily done in CLI.

Set all virtual disks to not mapped.


Once the WWNs are detected, adjust the host entries.

CLI# set host-name id profile


Then present the disks to the hosts:

map volume access rw ports a1,b1,a2,b2 lun host

Hope this helps!

Yes the server can see both MSAs if you have a zone with

hbawwn
msa1500wwn

and another zone with

hbawwn
msa2000wwn

you can do it other ways, like have the msa2000 wwn and the 1500 in the same. but if you separate them it makes truobleshooting easier

Re: MSA P2000fc G3 shows as a L port status.

Hey, SO thanks for all of the help and I have made good progress.

I changed the port type to point-point on the MSA 200 and they now show as F ports on the SAN switches and I have zones apropriately.

I setup the Host port names from the WWN on the MSA and created my VDisk and Volumes and mapped acordingly.

The issue I now have is the HP MPIO that I upgraded to the MSA 2000 version (W2003) does nto apear to be functioning as I see each volume twice, this makes sense due to multiple paths but I thought the MPIO would take care of this as it has on previous MSA deploys ??.........

Any Help/advice greatly apreciated!
