Determine the Availability of DCUs

The dcus_available property is a read-only property. Its values depend on the current assignment of DCUs and on the DCUs listed in the dcus_assignable property. Only DCUs listed as available can be assigned to a host. If a DCU is assigned to a host, it does not appear in the list of available DCUs. Also, if you changed the dcus_assignable property to exclude a specific DCU, that DCU does not appear in the list of available DCUs, even if it is not assigned to another host, until you change the dcus_assignable property.

This task uses PDomain_0, DCU2, DCU3 as examples.

1. Log in to Oracle ILOM.

   See Log In to Oracle ILOM (CLI).

2. Use one of these methods to check the availability of the DCUs.

   This example shows that only DCU2 and DCU3 are available for assignment to the host in PDomain_0.

   -> show /Servers/PDomains/PDomain_0/HOST
   ...
       Properties:
           alert_forwarding = disabled
           autorestart = reset
           autorunonerror = powercycle
           bootfailrecovery = poweroff
           bootrestart = none
           boottimeout = 0
           dcus_assignable = /SYS/DCU0 /SYS/DCU1 /SYS/DCU2 /SYS/DCU3
           dcus_assigned = /SYS/DCU0
           dcus_available = /SYS/DCU2 /SYS/DCU3
           dimm_sparing = enabled
   
   ...
   ->

   Or:

   -> show /Servers/PDomains/PDomain_0/HOST dcus_available
   
      /Servers/PDomains/PDomain_0/HOST
         Properties:
            dcus_available = /SYS/DCU2 /SYS/DCU3
   
   ->
