Oracle Linux Server 6.7 sobre un LDOM en Ultra Sparc T5

En este Articulo, se detalla un paso a paso , para la creacion de un ldom sobre un T5 , y posteriormente la instalacion de Oracle Linux Server 6.7, partiendo de la base que ya tenemos un PDOM con otros LDOMS creados, si tiene que crear un ldom paso a paso lea Este Articulo

El nombre que voy a usar de aqui en adelante para el zpool,hostname y todo lo relacionado a este ldom con oracle linux es "dorclx01" el nombre es por   d=desarrollo, orc=oracle lx=linux 01=Primer Ldom con linux

Primero creo un ZPOOL para el disco del SO
root@t5-2 # zpool create dorclx01_so c0t60050768018107A79000000000000CF3d0
root@t5-2 # zpool list
NAME          SIZE  ALLOC   FREE  CAP  DEDUP  HEALTH  ALTROOT

dorclx01_so  79.5G   126K  79.5G   0%  1.00x  ONLINE  -
laboratorio   199G  10.7G   188G   5%  1.00x  ONLINE  -
rpool         278G   102G   176G  36%  1.00x  ONLINE  -
root@t5-2 #
Le agrego el valor "none" al mountpoint para que No monte el zfs en el PDOM
root@t5-2 # zfs set mountpoint=none dorclx01_so
Creo un Volumen vol01, dentro del Zpool dorclx01 el cual luego lo usare para pasarselo al ldom y este sera visto como un disco, en el cual instalare el Sistema Operativo
root@t5-2 # zfs create -V 75g dorclx01_so/vol01

Ahora creo el LDOM
root@t5-2 # ldm add-domain dorclx01
root@t5-2 # ldm set-vcpu 8 dorclx01
root@t5-2 # ldm set-mem 8g dorclx01
root@t5-2 # ldm ls

root@t5-2 #
Agrego la placa de red y el switch al ldom
root@t5-2 # ldm add-vnet vnet1 vsw4 dorclx01
root@t5-2 # ldm add-vds dorclx01-vds0 primary
Agrego el virtual device ( el volumen que cree unas lineas mas arriba )
root@t5-2 #  ldm add-vdsdev /dev/zvol/dsk/dorclx01_so/vol01 vol01@dorclx01-vds0
Agrego los Virtual disk al ldom
root@t5-2 #  ldm add-vdisk vdisk1 vol01@dorclx01-vds0 dorclx01
Agrego la imagen ISO al primary
root@t5-2 # ldm add-vdsdev /sun/OL-201705232017-R6-U7-sparc-dvd.iso oracle-linux@primary-vds0
Agrego la imagen ISO al ldom
root@t5-2 # ldm add-vdisk oracle-linux oracle-linux@primary-vds0 dorclx01
Agrego el autoboot en False para que quede en OBP cuando bootee
root@t5-2 # ldm add-variable auto-boot?=false dorclx01
Le doy start al LDOM
root@t5-2 # ldm start dorclx01
LDom dorclx01 started
root@t5-2 #
