Migration of Stand Alone SCSI Data to Virtual SCSI Data _ IBM AIX Part III

Now we modify the VIOS Profile to add the SCSI Adapter which we removed from the AIX_Server.

Select the adapter and click on "Add as Required".


1) Login to VIOS as "padmin" and execute $ cfgdev


$ lsdev | grep vhost : Command to locate the newly created vhost adapter.

host0 Available Virtual SCSI Server Adapter

vhost1 Available Virtual SCSI Server Adapter

vhost2 Available Virtual SCSI Server Adapter

vhost3 Available Virtual SCSI Server Adapter

vhost4 Available Virtual SCSI Server Adapter


vhost4 is the newly created Virutal SCSI Server Adapter.


$ lsmap -vadapter vhost4


2) Now locate the new disk mapped to the VIOS.


$ lsdev -type disk

name status description

hdisk0 Available SAS Disk Drive

hdisk1 Available SAS Disk Drive

hdisk2 Available SAS Disk Drive

hdisk3 Available SAS Disk Drive

hdisk4 Available SAS Disk Drive

hdisk5 Available SAS Disk Drive

hdisk6 Available SAS Disk Drive

hdisk7 Available SAS Disk Drive

hdisk8 Available 16 Bit LVD SCSI Disk Drive


hdisk8 has been added and is a SCSI disk.


3) Confirm that the hdisk8 has the same UDID of the one found in AIX_Server.


$ chkdev -dev hdisk8 -verbose

NAME: hdisk8

IDENTIFIER: 22080004B9710BST3146807LC03IBMscsi

VIRT2NPIV_CAPABLE: NA

4) Now, map the disk from the VIOS to the Client Partition.


$ mkvdev -vdev hdisk8 -vadapter vhost4
vtscsi0 Available


5) Verify the mapping.


$ lsmap -all or lsmap -vadapter vhost4

$ lsmap -vadapter vhost4

Now login into the client partition and execute # cfgmgr and # lspv to locate the new disk.
