HP HSV200 SCSI Array Device

Mihai F — Sun, 28 Jun 2009 23:48:35 GMT

Hello,

I am new at the SAN configuration, so I need all the help I can get.

I was assigned to install and configura a SAN solution, and I hope I get the most part done. Here is what I have:
- one HP EVA 4100
- two HP StorageWorks 4/8 Base SAN Switches
- one HP DL380 G5 Base Storage Server
- one one MSL4048 LTO 4 Fiber Channel Tape Library

So far, after a huge amount of research I think I got the Switches configured, whit Aliases, and Zones to proper ports. Also, I created Disk groups, vdisks, and hoasts. Now I have to preset the disk to a hoast, but the server does not see any disk.
Looking at a different server, similar configuration as mine (on a different network, not the one I'm in) I saw in Device Manager, for the Disks, the "HP HSV200 SCSI Array Device", which does not show on my server. The only disks I see on my server, are the phisycal disks that the server has.
Could this be just a driver issue? Everything looks good in device manager; I don't have any pop-ups for installing any driver, but I still cannot see the Presented vdisk.
Is there any specific task involved on the server to see the presented vdisk? I just go in Disk Management and rescan for disks after any change I made, but still nothing.
What am I missing?
Any sugestions would be really appreciated.

Thank you

Did you install the HBA driver on the Server ?

Does the WWN of the HBA show up in the EVA4100 hosts lists ? if so then give the wwn's a alias using the server name.

Then use the presention tab on the Vdisk and present the lun to the server.

Then the server should see the lun in disk administrator, rescan your disks or reboot if it doesnt.

I forgot. you also need to install the Full function MPIO driver for the EVA4100 so you do not see multiple instances of the same disk in Disk Admin.

Thanks for the reply, Martin.
Unfortunatelly, is still not working.
Here are more details:
- the HBA drivers are install on the Server, and the ports are online:

Host Bus Adapter 0:
Location: Slot 2 (PCI bus 11, device 0, function 0)
Model: A8003A
Port WWN: 10.00.00.00.C9.72.AF.A2
Node WWN: 20.00.00.00.C9.72.AF.A2
Serial Number: MX308051H3
Driver description: Emulex LightPulse HBA - Multi-protocol Port Driver
Driver version: 5-2.42a0
Firmware version: 2.72A2
Option ROM version: 6.03A6
Port State: Online
Host Bus Adapter 1:
Location: Slot 2 (PCI bus 11, device 0, function 1)
Model: A8003A
Port WWN: 10.00.00.00.C9.72.AF.A1
Node WWN: 20.00.00.00.C9.72.AF.A1
Serial Number: MX308051H3
Driver description: Emulex LightPulse HBA - Multi-protocol Port Driver
Driver version: 5-2.42a0
Firmware version: 2.72A2
Option ROM version: 6.03A6
Port State: Online
- On CommandView EVA I created the Host, which has the same name as the Server name, and I added the correct San switch ports. Also, I created the Disk groups, the VDisks, and I Presented the VDisk to the Host.
I still cant see disk on the host (server) after I rescan fro disks in Disk Management.
Also, I have lights on the FC card, and on the Fiber module (I think is transciver) on the San switch, so the fiber cable in good.
The MPIO is installed. If I run HPDMS CLI>hpdms devices, I get the "No device found" message.
Is my first time dealing with a SAN configuration, so I'm stuck...I have no idea what can be wrong.
The Fiber cards are HP FC2242SR 4GB PCI-e DC HBA. I installed already the 3rd driver for it. Could you point witch vould be the right one?
Is there anything else I can do here?

If you can see the WWN's of the HBA's in CV under hosts, then that is a good sign that the zoning is correct or was correct. then is it just a matter of presenting the vdisk to the correct host. which you already did. You could double check that the Server HBA's are logged into the switch fabric by logging into both switches and check the nameserver. It will show you the HBA wwn, the driver and FW versions running on the HBA and the Port it is connected to. then you could verify that wwn with the wwn you see in CV which you assigned to the server alias name.

Re: HP HSV200 SCSI Array Device

Mihai F — Wed, 01 Jul 2009 18:45:34 GMT

Martin,

I have these two WWNs for this server:
XXXX-XXXX-XXXX-AFA1
XXXX-XXXX-XXXX-AFA2
I can see them on CV as Ports for the Host, on the SAN Switches (AFA1 on switch 1, and AFA2 on switch 2). Also, these WWNs show on the server's HBA adapter.
The Host on CV is the same as the Server name, and the same as the Alias on the San switches (I'm not sure about the relevance of this, but I just want to give you all the details I have)
Also, the Fiber cables are good...as I mentioned before, I have lights ON on the SAN switch, and on the Server FC card.
However, I still can't see the vdisk after I preset the Host.
This is anoying...eventhough I never had to deal with it before, but I feel like I'l 98% done with this task, and some small twick is stoping me from completing this task.
I appreciate all you help, and if you have any other ideas of what I can do, please let me know.

Thank you

here is a idea to see if the problem is the server or the Fabric/EVA. What server is running CV ? is it a different server than the 380G5 Storage Server ? if so then present the luns to the command view server to see if they appear there. If they do then the problem is definately with the DL380G5 HBA/SAN connection to the EVA.

Re: HP HSV200 SCSI Array Device

Mihai F — Wed, 01 Jul 2009 19:19:13 GMT

The CV is hosted by the so called Management Server, which came with the SAN cabinet, and is running Windows Storage Server 2003.
The host I'm presenting the VDISK to is a different one, a Windows Server 2003.
Bothe servers are DL380 G5.
The WWNs for both server are listed in CV. I actually added a host for the Management Server (the one running CV) because will need a VDISK also.
I have 3 more hosts, all on DL380 G5, and all the WWNs are showing in CV.

Re: HP HSV200 SCSI Array Device

Martin Smoral — Wed, 01 Jul 2009 19:22:53 GMT

great then unpresent the lun from the Storage Server where the lun is not showing up and try presenting it to the CV server or your other servers and see what happens. As long as your zoning is correct and CV see's the other hosts it should show up there too.

Re: HP HSV200 SCSI Array Device

Mihai F — Wed, 01 Jul 2009 19:46:52 GMT

I tried presenting the VDISK to the CV server and one other server, and still not able to see it.
So, should I start looking into the Switches configuration?
I gust that's what I'll start to dig into, tomorrow.
If you have any other sugestions where else I can look, I would appreciate.

Thank you.

Re: HP HSV200 SCSI Array Device

Martin Smoral — Wed, 01 Jul 2009 19:59:30 GMT

Only thing i can think of is that the wwn's in CV are old and not really available. Try deleting the wwn's/hosts in CV(probobly need to unpresent the vdisks form the host before you can delete them) for the servers that do not see their luns and see if they show back up. If they do not show up after deleting them, then there is a problem with the zoning. If they do show up, then sounds like the zoning is good.

Although the CV server wwn's must be good otherwize you would not be able to manage the EVA from there.

Martin,

I'm rebuilding the zoning on my switches to see maybe that helps. I am a litle confuse about the WWN #. If I run shitchshow, I see the WWN as 10:00....:af:a1, but if I use the WEBTOOL on that switch, after I create the Alias, for that particular port I have: Emulex Corporation 20:00:...:af:a1, then under this I see Emulex Corporation 10:00:...:af:a1 (the same number as showed in the switchshow result). If I click on any of these two, I have the Add Member enabled, and I actualli can add both two. My understanding is that I need to add the one that appears in the switchshow result, no?
That's what I did first time, but should I try the second one, that starts with 20:???

Thank you.

Re: HP HSV200 SCSI Array Device

Martin Smoral — Thu, 02 Jul 2009 14:15:57 GMT

I usually do everything from the Web admin Gui and just go to the zoning page. Create a Zone member alias (ie. SERVER1_hba1, SERVER1_hba2, EVA_CTRLA_FP1) for each of the wwn's then create a zone for each HBA/EVA Port and then add all those zones to a config, then activate the config.

Re: HP HSV200 SCSI Array Device

Mihai F — Thu, 02 Jul 2009 18:26:46 GMT

Ok, here is what I've done:
-on the switch1 and switch2 I created the Aliases for the server, and EVAs (Server1, EVAtop, EVAbot).
- I created the zone ZONEServer1, with Server1, EVAtop, and EVAbot as members. All the WWNs are assigned correct.
- saved and enabled the configuration, so everything looks good there.
- On CV, I created the host Server1 and added the ports as the WWNs that Server1 Alias has on the Switch1 and Switch2.
- created a VDisk, and presented to the host Server1.
- remote into server1 and reboot, rescan for disks, rescan for hardware changes...and still nothing...
I really don't know what else I can do :(

Martin Smoral — Thu, 02 Jul 2009 19:17:08 GMT

Wow i am running out of ideas. Under the Command View did you set the correct OS type to Windows. I can't remember if it is under Host or the Vidisk Presentation tab ?

Re: HP HSV200 SCSI Array Device

Mihai F — Thu, 02 Jul 2009 19:34:36 GMT

Yes, is under the Host, and I selected the Windows one, because I'm running Windows server 2003 on all the servers.
I don't know much about this, but it might be the Server (Host) that has the problem.
Could you please list for me the necessary software/drivers that I need on the host in order to see the VDISKs?
I have the latest full feature MPIO (HpMpioFFEVA3.03.zip), I have the "FC Port driver Emulexfcportkit_2-42a0-1c.exe" installed, I installed the "Microsoft Standard Dual Channel PCI IDE Controller Update.exe".
My Fiber Cards on the servers are "HP FC2242SR 4GB PCI-e DC HBA" (part A8003A) . Could you please point me to the right driver for it, just to make sure I have the right one?

Re: HP HSV200 SCSI Array Device

Martin Smoral — Thu, 02 Jul 2009 20:07:12 GMT

I would uninstall this "FC Port driver Emulexfcportkit_2-42a0-1c.exe" because i do not see it supported on the HP site and

get the W2003 HBA drivers here http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=1143907&prodTypeId=12169&prodSeriesId=1809835&swLang=8&taskId=135&swEnvOID=1005
looks like the lastest storport driver is 2.10x1 dated 22 Apr 2009

or

Re: HP HSV200 SCSI Array Device

Mihai F — Mon, 06 Jul 2009 14:14:21 GMT

Oh well...I did that and no luck..the Host still cannot see the VDISK.
I might call HP to see if I get any help from them.
BTW, I am not sure, but in my opinion the issue is at the Host level. Could you please list everything that I need to have install on the Host in order to communicate with the SAN? Any piece of software that I'm missiong? Or is there anything I can install to troubleshoot the communication between these two?

Re: HP HSV200 SCSI Array Device

Martin Smoral — Mon, 06 Jul 2009 19:40:25 GMT

I have another idea to see if it is a host problem or a EVA Problem. How about see if the Server can see the Fibre Tape library over the SAN Fabric. Just go to whichever switch the MSL is plugged into. Create a Alias for the MSL, then create a Zone called SERVERA_Backup and add the Server and MSL as members, then add that zone to the current config and re-enable it. Then go to the server and scan for new HW and see if it sees the MSL. If it does then the single HBA/Driver that goes to that switch seems to be working on the server and your doing the Zoning correctly.

Re: HP HSV200 SCSI Array Device

Mihai F — Mon, 06 Jul 2009 21:53:18 GMT

Wow...I finally got it to work.
Martin, I appreciate all your help...it helped me understand and learn a lot about the SAN configuration.
The problems was actually with the Cashe Battery Modules for both Enclosures. Both were deffective, and that was the reason the Hosts didn't see the Presented VDISKs.
I called HP, and they replaced the batteries for the controllers, and that was it...5 minutes after that, I Rescan for disks in Disk Management, and I was able to see the Presented VDISK.
I'he never thought that those batteries could cause the VDISK presentation to fell, withouth throwing any errors.
Also, thank you Martin for pointing me to the right software/drivers I needed for the Hosts. I'm pretty sure I would have had some issues withouth them.
Thanks again
