Montar iso o DVD sobre un LDOM
Ahora toca instalar el SO sobre el ldom aqui estan los pasos breves para montar un iso sobre el dominio.
root@t5120 # ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv- SP 8 2G 0.2% 21h 17m
ldg0 active -n---- 5000 8 512M 0.1% 15h 40m
ldg1 active -t---- 5001 8 512M 12% 21h 15m
ldg2 active -t---- 5002 8 512M 12% 21h 15m
root@t5120 #
Primero bajo el dominio en el cual quiero montar el SO que es el ldg1
root@t5120 # ldm stop ldg1
LDom ldg1 stopped
root@t5120 # ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv- SP 8 2G 0.3% 21h 17m
ldg0 active -n---- 5000 8 512M 0.1% 15h 41m
ldg1 bound ------ 5001 8 512M
ldg2 active -t---- 5002 8 512M 12% 21h 15m
root@t5120 #
Ahora de desenlaza el dominio con el comando
root@t5120 # ldm unbind ldg1
root@t5120 # ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv- SP 8 2G 2.0% 21h 19m
ldg0 active -n---- 5000 8 512M 0.1% 15h 42m
ldg2 active -t---- 5002 8 512M 12% 21h 17m
ldg1 inactive ------ 8 512M
root@t5120 #
Ahora si se puede añadir el iso desde el dominio primario
root@t5120 # ldm add-vdsdev /export/home/itc/install/V27764-01.iso iso_vol@primary-vds0
root@t5120 # ldm add-vdisk vdisk_iso iso_vol@primary-vds0 ldg1
root@t5120 #
root@t5120 # ldm bind ldg1
root@t5120 # ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv- SP 8 2G 2.2% 21h 35m
ldg1 bound ------ 5000 8 512M
ldg2 active -t---- 5002 8 512M 12% 21h 32m
ldg0 inactive ------ 8 512M
root@t5120 #
root@t5120 # ldm start ldg1
LDom ldg1 started
root@t5120 # ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv- SP 8 2G 0.2% 21h 35m
ldg1 active -t---- 5000 8 512M 4.6% 2s
ldg2 active -t---- 5002 8 512M 12% 21h 33m
ldg0 inactive ------ 8 512M

Para remover hay que seguir el siguiente orden.
1 Parar el dominio
2 Desenlazar el dominio
3 Remover el disco con el comando
ldm remove-vdisk [-f] disk-name ldom
root@t5120 # ldm remove-vdisk vdisk_iso ldg0
4 Remover el device entregado al dominio con:
ldm remove-vdsdev [-f] volume-name@service-n
root@t5120 # ldm remove-vdsdev iso_vol@primary-vds0
root@t5120 #
Thats all!!
