VIOS Operation-3

Management of Virtual/Shared Devices:

To create a virtual target device that maps lv20 as a virtual disk for a client partition hosted by the vhost0 virtual server adapter :

# mkvdev -vdev lv20 -vadapter vhost0

To create a virtual target device that maps hdisk5 as a virtual disk for a client partition hosted by the vhost1 virtual server adapter :

# mkvdev -vdev hdisk5 -vadapter vhost1

To create a SEA that maps the physical Ethernet adapter ent4 as a virtual adapter for the clien tpartitions served by the virtual Ethernet adapters ent6 and ent7, using ent6 as the default adapter and 8 as the default id :

# mkvdev -sea ent4 -vadapter ent6,ent7 -default ent6 -defaultid 8

Assign IP Address:

# mktcpip -hostname <Hostname> -interface ent# -inetaddr <IP> -netmask -gateway <IP> -start

To remove a virtual target device vtscsi9 along with its backing lv:

# rmdev -vdev vtscsi9

To remove all virtual target device associated with backing device lv001 :

# rmdev -vdev lv001

To remove a specific virtual target device :

# rmdev -vtd vtscsi0

Device Configurations:


1) # cfgdev /*To configures the devices in the VIO server*/


2) # cfgdev -dev  /*To configures the devices attached to scsi0 adapter*/


3) # chdev -dev <****> -attr <attribute=value> -perm /*To change the attribute of a device permanently*/


4) # chpath -dev hdisk1 -pdev scsi0 -op disable /*To disable the path between hdisk1 and scsi0*/


5) # rmdev -dev /dev/cd0 /*To unconfigure the cd-rom device*/


6) # rmdev -recursive -dev scsi /*To unconfigure scsi adapter and its child devices*/


7) # rmdev -pdev pci0  /* To unconfigures the children of pci1 but not the PCI bus pci1 */
