problem by assigning AVIO disk

[Eli Daniel]

hello,
this day update the vm guest and host to version 3.5
the disk were changes by AVIO.
the update was successful
I need to add two new disk to the guest to date, but displays the following error:
************************************************** ***************
05/29/10 12:55:15 | ERROR | SAPL909 | root | Conflicting Device has device address - bus 0, dev 0, func 0, target 1, lun 0.
05/29/10 12:55:15 | ERROR | SAPL909 | root | Unable to add device '/ dev/rdsk/c35t2d3'.
************************************************** ***************
Use the following command:
hpvmmodify-p 1-a disk: avio_stor: 0,0,1: disk: / dev/rdsk/c35t2d3.
************************************************** ***********************
command applies to the VM guest running.

[melvyn burnard]

so what does an hpvmstatus -p 1 show as already configured?

[Eli Daniel]

all are configured disk AVIO_STOR

[Eli Daniel]

The server is Produccion. I nedd assigned 2 disk new. the VM Guest has assigned 30 disk. were migrated from VIO to AVIO_STOR.
HELPME PLEASE

[Eli Daniel]

I think the problem is:
bus 0, dev 0, func 0, target 1, lun 0
is being used in one of the disk that have already been allocated.
I can change the new disk in this direction?
00010 c35t2d3

disk assigned already in the VM guest.
Guest Device type : disk
Guest Adaptor type : avio_stor
Bus : 0
Device : 0
Function : 0
Target : 1
Lun : 0
Physical Storage type : disk
Physical Device : /dev/rdsk/c39t1d2

Hi Daniel,

>> Conflicting Device has device address - bus 0, dev 0, func 0, target 1, lun 0.
Yes, the device address is already being used and hence allocated to another
disk.When the new disk also refers to the same address, a conflict is reported.

Using the hpvmmodify command for the new disk should solve the problem.

Hi,

Can you provide hpvmstatus -P vmname output
also hpvmdevmgmt -l all


Chandra

[melvyn burnard]

Like I said, what does hpvmstatus -v -p 1 show as copnfigured, if you had posted here we could actually see rather than guess what is already configured

[Eli Daniel]

I am using the command hpvmmodify but can not resolve the fault

[Eli Daniel]

Hi Daniel,

>> I am using the command hpvmmodify but can not resolve the fault
what error are you getting ?

Regards,
Murali

[Eli Daniel]

hpvmmodify-p 1-a disk: avio_stor: 0,0,1: disk: / dev/rdsk/c35t2d3

| ERROR | SAPL909 | root | Conflicting Device has device address - bus 0, dev 0, func 0, target 1, lun 0.

hpvmmodify -p1 = SAPL909


Note: the hpvmstatus to send a few minutes ago the lun 001 is used by another disk.

I think that's the problem

[P Muralidhar Kini · Accepted solution]

Hi Daniel,

From the output you have provided,

>>SINFRA94:/> hpvmstatus -p1
>>...
>> disk avio_stor 0 0 0 1 0 disk /dev/rdsk/c39t1d2

The combination of bus=0,dev=0,func=0,target=1,lun=0 is already allocated
to the device "/dev/rdsk/c39t1d2". Hence when you try to assing the same
values to a different device "/dev/rdsk/c35t2d3" using hpvmmodify, you
are getting the following error -
>> | ERROR | SAPL909 | root | Conflicting Device has device address
>> - bus 0, dev 0, func 0, target 1, lun 0.
This is the cause for the problem.

You need to give the hpvmmodify command for the device "/dev/rdsk/c35t2d3"
with its corresponding values for bus,dev,func,target,lun.
This should solve the problem.

Regards,
Murali

[Eli Daniel]

yes, that's exactly what I need.
attempt to locate bus, dev, func, target and lun of the device wiht command gvsdmg, but the command does not host.

there is another way to locate the data disk?

[P Muralidhar Kini]

Hi Daniel,

How about a IOSCAN command to locate the disk.

Check the following link -
http://docs.hp.com/en/B2355-60130/ioscan.1M.html
-> This talks about the IOSCAN command and its options.

Murali

[Eli Daniel]

disk 204 0/0/4/1/0/4/1.20.36.0.0.2.3 sdisk CLAIMED DEVICE EMC SYMMETRIX
/dev/dsk/c35t2d3 /dev/rdsk/c35t2d3

I dont understand. which are the values?

[P Muralidhar Kini]

Hi Daniel,

The IOSCAN is giving the hardware path.
To map this to the Bus/Dev ... etc, refer the following link -
http://docs.hp.com/en/T2767-90179/ch08s17.html
-> section "Mapping AVIO Storage Devices on 11i v2 Guests"

The link also talks about the gvsdmgr utility.

Hope this helps.

Murali

[Eli Daniel]

in the case the path disk is:

disk 204 0/0/4/1/0/4/1.20.36.0.0.2.3 sdisk CLAIMED DEVICE EMC SYMMETRIX
/dev/dsk/c35t2d3 /dev/rdsk/c35t2d3

040 /dev/dsk/c35t2d3

this correct?

[P Muralidhar Kini]

Hi Daniel,

In the above link, they are mapping the output of # ioscan -fne
to Bus, Dev ...

What does the output of "#ioscan -fne" look like?

Regards,
Murali

[Chandrahasa s]

disk avio_stor 0 0 0 1 0 disk /dev/rdsk/c39t1d2


is the disk which causes this problem

you logon to guest machine and find out this disk from ioscan output

this disk will be as like

c0t1d0

find out which vg have this disk

umount mount points which are comes under this

vgexport -p -m /tmp/vgname.map vgname

take details of all pvs whiech are comes under this vg

vgchange -a n vgname

vgexport

remove this from guest using hpvmmodify

add your new disk

trace disk in vmguest

add your old disk

trace out in guest

vgimport -v -m /tmp/vgname.map vgname pvs...

if it gives error
simply vgimport -v vgname pvs...

this will solve your problem

[Eli Daniel]

Chandrahasa, the problem is that not what the (Bus,Slot,Tgt) the disk in the host.
if I find such data correctly I can assign the disk to the VM guest.

disk in the host:
disk 204 0/0/4/1/0/4/1.20.36.0.0.2.3 sdisk CLAIMED DEVICE EMC SYMMETRIX
/dev/dsk/c35t2d3 /dev/rdsk/c35t2d3

[P Muralidhar Kini]

Hi Daniel,

The output you have provided looks different from what is mentionedin the link.
Provide the output of "#ioscan -fne". The above link talks about decoding this output.
