ioscan -funC disk shows NO_HW

[kaushikbr]

Hi,

We have a rx7620 based servers using EVA3000 storage and running HP-UX B11.23.

We had a power outage in our datacenter.
Since then we have restarted the machine,
after the machine restart I am unable to see the diskgroups on the EVA, and the ioscan -funC disk comes back with the below shown results.
I have refered to the itrc website where this gentelman "Ben Dehner" had a similar problem, but seems he has a different issue.

http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1117490

We have tried to restart the Fibre switch, The EVA and then the machine.. no luck.

Also this is on a 2 node cluster, we are unable to see the storage from either members.
Since these disk groups are used as VGs for the Serviceguard packages, the packages also fails to start. I have verified if the vg is in a stale state. I cannot do vgchange, I cannot do a vgdisplay.... I have copied the results of vgchange and vgdisplay as well.

Thanks in advance for all your valuable suggestions.
Regards
Kaushik

Looks like you aren't seeing any FC disks at all. As you have the same problem with both nodes of the cluster, it's likely the problem is with the common elements... i.e. the fibre switch, the EVA or the connection between them.

But let's start with the basics.
First run "ioscan -fnCfc" to get the device names of the FibreChannel HBAs. Then use "fcmsutil " to see the state of the HBAs... if the cards are not READY/ONLINE, there may be a problem with the physical connection or the transmitters of the Fibre switch.

If the physical connection is OK and the HBAs are seeing the light from the switch (and vice versa), the EVA and/or the switch may have lost its configuration data. I hope you have the configurations of the EVA and the switch well documented. If you have actually backed up the configuration data somewhere safe, that would be great.

[Duncan Edmonstone]

What sort of FC switches do you have? Some switches (specifically Cisco), if not setup correctly can cause HPUX hardware paths to change every time the switches are rebooted.

ioscan and fcmsutil looks good... Have you tried resetting the card which is showing all the connected devices as NO_HW..

If not then try doing that using:

fcmsutil reset

[Duncan Edmonstone]

Hi,

No thats the HBA in the server - at the other end of the cable coming out of your server will be a FC switch - what model is that?

HTH

Duncan

[Torsten.]

You already know the WWN's from the commands above, e.g.

N_Port Node World Wide Name = 0x50060b0000300cfd
N_Port Port World Wide Name = 0x50060b0000300cfc

Now connect to the switch and check the status of the ports, e.g. B-series "switchshow"

[mmax]

hello,
it'll be good to run

ioscan -fnH 1/0/4/1/0

and

ioscan -fnH 0 0/0/12/1/0

to check if you see other devices for example domains.
maybe after that you can check switchshow/zoneshow etc on the switches.

[kaushikbr]

Hi All,

Once again thank you all for your valuable replies.

Mridul : The reset command apparently will abort the communication to all nodes. Is it safe to run this command or do I have to do anything else before I can run this ?

Duncan, Torsten : Since I am not onsite, I am trying to get someone to connect to the switch to try the switchshow command & also to find out the model of the FC switch.

Michal : I have copied the results of the two commands you have asked for. I observed one strange behaviour. I have tried this command on both members of the cluster. These commands give more info on one node and not so much on the other. ( nuncas01 & nuncas02 are the two members)

looks like you are able to see the SAN drives.If not,can u rescan the drives by running the command #ioscan -fnC disk
lets see the system can detect the drives or not.

[mmax]

hi kaushikbr
Are you using something like securepath? because we're looking on sdisks from HSV100 controler from HW pathes 255/255/0/*. This adress is ussually reserved by securepath devices.
As you can see CLAIMED sdisks with HW pathes 1/0/4/1/0 and 0/0/12/1/0 we will not find any problem with SAN or somebody changed SAN infrastructure.
Check if you are running spagent
# ps -ef | grep spagent

and try to check spmgr
# spmgr display -d
# spmgr display -a
This command should show you some output with devices grouped under securepath.

hi kaushik.
I forgot to put verbose to command

# spmgr display -dv
will display all devices which are configured via securepath
# spmgr display -av td0
will display all devices mapped via /dev/td0 adapter
# spmgr display -av td1
will display devices visible via /dev/td1

pls could you paste this outputs here? after that we should check securepath on the system.
also pls run
# ioscan -fn | grep NO_HW
to check if you have really refreshed ioscan output (and not something what is cached). Sometime it happens that ioscan -fnC disk don't show exact info

[kaushikbr]

Hi All,

It has been some time since I have started this thread. We had a few issues in resolving this problem. We had a few hardware problems and other problems with this. We had a cache battery failure infact both battries were busted. We have now replaced the cache batteries and sorted out all the other issues ( nothing to do with hardware or the OS ). We are having a different problem. These clusters are configured with redundant fiber cards, san switches etc. When I run the "fcmsutil" command on the two cards I see on card is ONLINE and the other is UNINITIALIZED. Dont understand why and how to make it online.

Thanks and regards
Kaushik

[Torsten.]

The status is "Driver state = AWAITING_LINK_UP ".

You should check the switch setting for this port, the port on the switch and the server itself and last but not least the cable.

The server can't see any light from the switch and vice versa, probably.

[kaushikbr]

Hi Torsten

That was indeed a problem with no_light.
What I found from the SAN switches, the no_light corresponds to the td1 port.
However what I dont understand is we have dual fibre cards and they are both configured. And I still cannot see the HSV disks. I am an not sure what is the problem.

Looks to me like you have 2 problems:

on one switch there is a connection between the switch and the EVA, on the second switch there is a connection from the switch to the server - BUT there is no connection between the server and the EVA!

Check the cabling and ports again.
Maybe the cables are "twisted" and receiver meets receiver but not transceiver.

Be aware of the laser light, but can you see a red light coming out of the ports (you can use a sheet of paper and hold it in front of the port).

Hi

I found something else as well.
We have secure agent installed as well on these clusters.

VVT-nuncas01-TeMIP # spmgr display

All devices on this Storage System are either deleted or not discovered.

I dont know if I should be worried.
I dont have any experience on spagent.

Thanks and regards

Hi

While going through some of the threads in the forum I found the command "fcmsutil /dev/td0 get remote all".

When I run this command on our hardware this is what I get

VVT-nuncas01-TeMIP # fcmsutil /dev/td0 get remote all

No device found.

I can understand when I chose td1 I get No Device found. However for td0 the target state is "DVS_UNOPENED". Can please shed some light.

Thanks and regards
