Please, I need help
execute on host server1 command fcmsutil / dev / fcdx
shows all fiber channels.

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

[Torsten. · Accepted solution]

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

hpvmstatus (per guest) will tell you.

[Steven E. Protter]

Shalom,

Not exactly straightforward it seems:

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

[Tingli]

Use ioscan to find it out.

from the HPVMHOST

# ioscan -fnC fc

from the Guest.

#ioscan -fnC fc

[Kapil Jha]

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 :)

BR,
Kapil+

[Torsten.]

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.

[Eli Daniel]

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

[Eli Daniel]

anex ioscan VM HOST

[Torsten.]

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

[Eli Daniel]

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

[Torsten.]

Probably all, with multipathing in use.

[Eli Daniel]

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

[Torsten.]

Multipathing in use???

[Eli Daniel]

do not know. how can I validate this information?

[Torsten.]

Looking into swlist could be the first step.

[Eli Daniel]

Torsten anex swlist product in the server host

[Torsten.]

PowerPath is installed.

[Eli Daniel]

actually installed. does this have any impact with the hba's.
power path installed the operation system is Multipathing?

[Torsten.]

I don't work with EMCs, but multipathing is used for load balancing in general, hence all available paths (all HBAs) are used.

[Eli Daniel]

Thanks for information
