• There is a deconfigured CPU which has been reserved for the partition as part of a CLP
request (cell:cell_ID:cpu:num) and there are no free CLP in that cell. To correct this, you
can make available CPUs from that cell by deleting the CPUs that are part of this cell from
other partitions or delete the CPUs from the cell in this partition.
(A.03 and earlier) On a vPars system, for bound CPUs, the virtual partition boots with the CPU
marked for deconfiguration. For unbound CPUs, the Monitor will attempt to replaced the
marked CPUs with a working CPU; however, if no working CPUs are available, the Monitor
automatically reduces the unbound CPU number for that virtual partition in the vPars
database and allows the virtual partition to boot with the working CPUs.
The PA-8800s are dual-core sockets: they have two CPUs per socket. Deactivation happens on a
processor level, but deconfiguration happens at the socket level. If a socket is deconfigured,
both processors sharing the socket will be unavailable.
(Integrity only) If a CPU is marked for deconfiguration using an EFI command and the
nPartition is not rebooted (for example, the vPars Monitor is immediately booted), the vPars
Monitor will not know or indicate (including with vparstatus) that the CPU has been marked
for deconfiguration and will use the CPU like any other working CPU.
