CREATING AND ASSIGNING LV AS A DISK TO LPAR FROM VIO(STEP BY STEP SCREENSHOTS)
On the vio server
Check status of virtual adapters before creating adapters
$ lsmap -all |grep vhost
vhost9 Available Virtual SCSI Server Adapter
vhost10 Available Virtual SCSI Server Adapter
vhost11 Available Virtual SCSI Server Adapter
vhost12 Available Virtual SCSI Server Adapter
vhost13 Available Virtual SCSI Server Adapter
vhost14 Available Virtual SCSI Server Adapter
vhost15 Available Virtual SCSI Server Adapter
vhost16 Available Virtual SCSI Server Adapter
vhost18 Available Virtual SCSI Server Adapter
vsa0 Available LPAR Virtual Serial Adapter CREATE A SCSI SERVER ADAPTER ON THE VIO
To create a scsi server adapter we have to create a scsi adapter at vio server side In the hmc server section select the box on which you are going to do operation
select the lpar from the list of lpars and click on the small arrow besides the lpar this arrow is a shortcut to the tasks option on the top
From the DLPAR options select the virtual adapters
Select create
SCSI adapters
When we create a scsi server adapter we have to be carefull about the server adapter id this id will corrospond to the respective client adapter to which this adapter will serve . This is just like creating a target and a initiator where server adapter is target and client adapter is initiator
Note the server adapter ID , here 31 , While creating client adapter this id will be
used to create a mapping
Note :Scsi Server adapters can only be created on VIO server and client adapters can only
be created on client lparsCheck whether the new virtual adapter is available now
$ lsmap -all |grep vhost
vhost14 Available Virtual SCSI Server Adapter
vhost15 Available Virtual SCSI Server Adapter
vhost16 Available Virtual SCSI Server Adapter
vhost17 Available Virtual SCSI Server Adapter
vhost18 Available Virtual SCSI Server Adapter
vhost19 Available Virtual SCSI Server Adapter
vsa0 Available LPAR Virtual Serial Adapter
# exit
We can see a new virtual adapter vhost19 which we created just now
$ lsvg lpar_vg
VOLUME GROUP: lpar_vg VG IDENTIFIER: 00cf21f100004c000000011bda37a9cc
VG PERMISSION: read/write TOTAL PPs: 2730(698880 megabytes)
MAX LVs: 512 FREE PPs: 1098(281088 megabytes)
LVs: 6 USED PPs: 1632(417792 megaby
Check what LV's are available on this VG
$ lsvg -lv lpar_vg
lpar_vg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNTPOINT
D3-APP111-LV00 jfs 272 272 1 open/syncd N/A
D4-APP109-LV00 jfs 272 272 1 open/syncd N/A
D4-APP123-LV00 jfs 272 272 1 open/syncd N/A
D3-APP112-LV00 jfs 272 272 1 open/syncd N/A
D2-APP124-LV00 jfs 272 272 1 open/syncd N/A
D2-APP110-LV00 jfs 272 272 1 open/syncd N/A
Now we will create a LV named testlv in the VG lpar_vg , this lv will act as a disk device for the client LPAR
Create a logical volume ‘testlv’ in the lpar_vg
Check the space availability in the vg
$ mklv -lv testlv lpar_vg 8
testlv
Now we will add a client adapter in the client LPAR , note the server adapter id is the same , one we created above and the client adapter id is also same which was given above
Add client scsi adapter on the Client lpar
SELECT DYNAMIC LOGICAL PARTITIONING >> SELECET VIRTUAL ADAPTERS
Now to verify the client adapter go to the client and run device configuration utility
# cfgmgr
Check the availability of adapter
Check the availability of adapter
# lsdev -Cc adapter

vscsi2 Available Virtual SCSI Client Adapter
Now we can see the new adapter vscsi2 available at the client side
For verification we are just showing what are the disks present at the client side
# lspv

Map testlv to the new virtual adapter
$ lsmap -vadapter vhost19

Run mkvdev command to created a virtual target device with virtual adapter
$ mkvdev -vdev testlv -vadapter vhost19

$ lsmap -all -field vtd

Now goto client side and run device configuration utility . verify the new disk same size as of LV created at VIO server

run cfgmgr
#cfgmgr

#cfgmgr
# bootinfo -s hdisk6
hdisk6 none None
Verify that the disk is of same space equivalent to lv
REMOVING DISK AND ADAPTER PROVIDED FROM VIO
Remove the disk at client side
# rmdev -dl hdisk6
hdisk6 deleted
Remove the virtual scsi adapter at the client lpar
# rmdev -dl vscsi2
vscsi2 deleted
Remove the vadapter from the hmc from client side
On vio server remove the virtual adapter and target device
$ rmvdev -vdev testlv
