Please, I need help

exist in the host server 3 Virtual Machine. I need to know which cards are allocated to each Virtual Machine. As I do?

Did you assign "raw" disks, LVOLS or files???

hpvmstatus (per guest) will tell you.

Now if you look at the logical volume assigned to the system and then go to the host OS you can from ioscan output and fcmsutil show what is attached.

Then you look at the vgdisplay output and you can figure out what fiber card is being used.

However guests do not get exclusive access to the fiber cards. They get access to resources given to them by the hpvm manager.

It is quite possible to take two luns off the same fiber card and assign them to two virtual guests.

anex the information Virtual Machine
I do not see where is the path of fibra channel for Virtual Machine

Re: Command fcmsutil

Tingli — Tue, 02 Mar 2010 21:35:24 GMT

Use ioscan to find it out.

from the HPVMHOST

# ioscan -fnC fc

from the Guest.

#ioscan -fnC fc

Re: Command fcmsutil

Kapil Jha — Wed, 03 Mar 2010 02:30:41 GMT

I think fc is not assigned to Virtual host, its just disks which are assigned.
So you would not be able to get any status of fc from ioscan in guest.

Remember when you create a new VM you don assign fc card anywhere :)

Re: Command fcmsutil

Torsten. — Wed, 03 Mar 2010 05:27:39 GMT

From guest config:

disk scsi 0 4 0 6 0 disk /dev/rdsk/c41t7d5
disk scsi 0 4 0 7 0 lv /dev/vgeccLogR1/rlveccLogR11

So you use raw disks and LVOLs as virtual disks.

I assume the host is on 11.31 or 11.23 with multipath, you can be sure all FC HBAs are used for load balancing.

Now use ioscan and vgdisplay from HPVMhost to get the connection details.

Re: Command fcmsutil

Eli Daniel — Wed, 03 Mar 2010 12:43:32 GMT

from what I understand, all cards chanell Host fiber can be used for any virtual machine???

The problem is this: be assigned to discs from the SAM VMHost and then assign them to the Virtual Machine. I need to know that fiber card uses the Virtual Machine.

Yes, my Operation System is 11.23 HP-UX

Re: Command fcmsutil

Eli Daniel — Wed, 03 Mar 2010 12:56:08 GMT

anex ioscan VM HOST

Re: Command fcmsutil

Torsten. — Wed, 03 Mar 2010 15:14:55 GMT

As said, you assign disks or lvols or files, but you never assign hba's.

Re: Command fcmsutil

Eli Daniel — Wed, 03 Mar 2010 15:25:06 GMT

I agree.
really needed to know was which of the 6 hba's were required to allocate disk from the SAM

Re: Command fcmsutil

Torsten. — Wed, 03 Mar 2010 15:30:51 GMT

Probably all, with multipathing in use.

Re: Command fcmsutil

Eli Daniel — Wed, 03 Mar 2010 15:35:36 GMT

I needed exactly.
if disks are allocated from the SAM, I can use any hba's (6 available)
this is correct?

Re: Command fcmsutil

Torsten. — Wed, 03 Mar 2010 15:38:34 GMT

Multipathing in use???

Re: Command fcmsutil

Eli Daniel — Wed, 03 Mar 2010 15:45:34 GMT

do not know. how can I validate this information?

Re: Command fcmsutil

Torsten. — Wed, 03 Mar 2010 15:59:47 GMT

Looking into swlist could be the first step.

Re: Command fcmsutil
