Hi,

Screenshot says it's an HSV200. This is not an EVA4400.
From screenshot it looks like there is only one controller. What happened to the other one? How is the server connected? Via a switch? Is the server zoned to both?

Latest XCS is 6250, are you running an old version of CV too?

When the EVA becomes invisible from CV - can you still see it via "cvutil paths" and can servers still see their disks?

HSV200 is an EVA4000 - what does the front panel show now?

The controller model is HSV200 & storage model is EVA 4400 only.

The controller become invisible automatically from EVA. The server is connected via SAN Switch.

XCS is self upgradable or we need support from HP. If yes where i can download.

Yesterday it become invisible and where to run the "cvutil paths" command.

Nothing in front panel?

How about all the LEDs in front and back compared to the working controller?

XCS can be downloaded from software.hp.com - it is a bit tricky though. You might need to upgrade Command View as well. Read the Updating Products Software Guide and release notes carefully.

cvutil.exe comes with command view it should be installed in the same directory as cv.

"controller becomes invisible from EVA" - what do you mean? Invisible from the Command View?

Torsten... Not at all any difference and it looks same as controller B..... all the LED's fine in both enclosure

Is it always the same controller that goes missing?

When it's invisible you can then check cvutil or the SAN-switch and see if the missing EVA controller is visible there. If controller is not visible in switch then it means your server is probably OK. Check portstats on the switch-sides.

Check if the controller ports are also logged in to the SAN switch(es?).

Re: Eva 4400 One controller become invisible from COmmand view EVA

MohankumarK — Tue, 09 Apr 2013 15:00:45 GMT

Johan Guldmyr...

In SAN Switch side ports are online and showing fine and also no port errors shows in switch end.

Kindly suggest further...

Controller A :-

26 26 0b1a00 id N2 Online FC F-Port 50:00:1f:e1:50:08:5f:e8

26 26 0c1a00 id N2 Online FC F-Port 50:00:1f:e1:50:08:5f:e9

Controller B :

Host ports

OK, so you have zoning between the management server and the EVA controllers in Fabric with Domain ID c.

Check both switches if any of the ports related have errors.

When the Controller goes missing from Command View - is it also going missing from servers that have LUNs presented to them? - Are you losing any paths on those servers?

I don't have the tools to analyze the logs, but perhaps you can look through the Controller Event Logs from around the time when the controller went missing..

Hi ..

only one VDSIK is not showing controller name.

onlinecontroller
controllername = n/a
controllerid = 00000708B4080550355810000000000000000000
operationalstate = good
operationalstatedetail = operating_normally
osunitid = 0

Remaining all the VDISK are showing controller name a controller B

onlinecontroller
controllername = Controller B
controllerid = 00000708B40805506F4210000000000000000000
operationalstate = good
operationalstatedetail = operating_normally

Please help me and suggest further

MohankumarK — Wed, 10 Apr 2013 16:27:05 GMT

Johan Guldmyr. & Torsten.

Verified the zoning and recreated zoning on my san switch as below

SERVER PORT A + CONTROLER A FP1 +CONTROLER B FP1 = FABRIC 1

SERVER PORT B + CONTROLER A FP2 +CONTROLER B FP2 = FABRIC 2

Post Configuration i have rebooted the managment server. now in command view EVA am able to see the both a controller . and also CV util exe showing below. paths.

Kindly suggest me further
